- How do I start program xyz?There are several way how to start a certain programm, here are the most common:\r\n\r\n* Start your program via your $HOME/.xinitrc:\r\n\r\n\r\nsubtle &\r\nPID=$!\r\nsleep 2\r\nurxvt\r\nwait $PID\r\n\r\n\r\n* Start your program via grab:\r\n\r\n\r\n"A-x" => "urxvt"\r\n\r\n\r\n_dmenu is added as default launcher in the distributed config to make it more convenient._
- How do I move program xyz to view abc?Placement in subtle is strict and completely done via the tagging system and is initially usually done in the config.\r\n\r\nYou can change tags either with subtler or subtlext per runtime:\r\n\r\nSubtler:\r\n\r\nsubtler -ta tag #< Add new tag 'tag'\r\nsubtler -cT view tag #< Tag view 'view' with tag 'tag'\r\nsubtler -vT client tag #< Tag client 'client' with tag 'tag'\r\n\r\n\r\nSubtlext:\r\n\r\ns = Subtlext::Subtle.new #< Connect to subtle\r\ns.find_client("client").tag("tag") #< Tag client 'client' with tag 'tag'\r\ns.find_view("view").tag("tag") #< Tag view 'view' with tag 'tag'\r\n\r\n\r\nIn /usr/share/subtle/scripts is a tagging example script with the help of dmenu.

- How does subtle match clients?Subtle matches the {{color(#ff0000, WM_NAME)}} and the {{color(#0000ff, WM_CLASS)}} property of a window and not the title. This to ensure the match is correct. \r\nThere are several ways to get these values, here are the most common:\r\n\r\n* xprop: Just select the window and have a look for the WM_CLASS line which usually look like this:\r\n\r\np{class:pre}. WM_CLASS(STRING) = "{{color(#ff0000, urxvt)}}", "{{color(#0000ff, URxvt)}}")\r\n\r\n* subtler: Run subtler cl and look for the matching line:\r\n\r\np{class:pre}. 0x800007 * 1 1020x374 2 1 -- {{color(#ff0000, urxvt)}} ({{color(#0000ff,URxvt)}})

- How do I set a wallpaper in subtle?subtle itself has no own functionality to set a wallpaper, ~/.xinitrc is perfectly suited for this. \r\n\r\nDue the design of subtle sets background color of the root window and therefore overwrites any root pixmap set before. \r\n\r\nThis can be bypassed with this:\r\n\r\nsubtle &\r\nPID=$!\r\ndisplay -window root pixmap.png\r\nwait $PID\r\n

- How do I run a java program?Java expects a certain behaviour (reparenting of client windows) of a window manager which is not part of any standard, therefore some Java programs just show a white canvas.\r\n\r\nIf this happens just try to start your program like this:\r\n\r\nAWT_TOOLKIT=MToolkit program\r\n\r\nThis changes the default tookit of Java to MToolkit, which is known to work with non-reparenting windows managers like subtle. Dependend on your OpenJDK version and your architecture this may either lead to a segmentation fault or your OpenJDK just has no support for MToolkit.

- How do I add tags to console based programs?Generally subtle can apply tags based on the {{color(#0000ff, WM_NAME)}} and both {{color(#ff0000, WM_CLASS)}} components. Console based programs like irssi can be started like this and will change the {{color(#0000ff, WM_NAME)}} of the terminal:\r\n\r\nurxvt -e irssi\r\n\r\nInspecting the terminal with xprop{{color(#0000ff, WM_NAME)}}(STRING) = "irssi"\r\n{{color(#ff0000, WM_CLASS)}}(STRING) = {{color(#aa0000, "urxvt")}}, {{color(#ff00ff, "URxvt")}}\r\n\r\nSo if we want to tag this window there are some things that should be considered:\r\n\r\n* irssi updates the {{color(#0000ff, WM_NAME)}} only\r\n* Tagging matches per default both {{color(#ff0000, WM_CLASS)}} components ({{color(#aa0000, instance)}} and {{color(#ff00ff, class)}} name)\r\n* Tags are applied when a window is mapped - that is before the terminal launches irssi safely tag it's better to change the {{color(#aa0000, instance)}} name of the terminal like this:\r\n\r\nurxvt -name irssi -e irssi\r\n\r\nThis results in following (via xprop{{color(#0000ff, WM_NAME)}}(STRING) = "irssi"\r\n{{color(#ff0000, WM_CLASS)}}(STRING) = {{color(#aa0000, "irssi")}}, {{color(#ff00ff, "URxvt")}}\r\n\r\nA tag for this could be:\r\n\r\ntag "irssi" do\r\n match "irssi"\r\nend\r\n\r\nPlease keep in mind, that the {{color(#ff0000, WM_CLASS)}} {{color(#ff00ff, class)}} name is still URxvt and will match others tags too.

- How can I use subtle without numpad?Per default subtle uses the numpad, because it's easier to remind the different postions when you can see them. Generally this is just a suggestion, it's up to you to change the grabs to your needs - any keys will work. \r\n\r\nKeys that also have proven to work well are q-w-e, a-s-d and y-x-c:\r\n\r\ngrab "W-q", [ :top_left, :top_left66, :top_left33 ]\r\ngrab "W-w", [ :top, :top66, :top33 ]\r\ngrab "W-e", [ :top_right, :top_right66, :top_right33 ]\r\ngrab "W-a", [ :left, :left66, :left33 ]\r\ngrab "W-s", [ :center, :center66, :center33 ]\r\ngrab "W-d", [ :right, :right66, :right33 ]\r\ngrab "W-y", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\ngrab "W-x", [ :bottom, :bottom66, :bottom33 ]\r\ngrab "W-c", [ :bottom_right, :bottom_right66, :bottom_right33 ]\r\n\r\n\r\nYou can find more about assigning keys here.

- How do I run a program on startup?Let's say you want urxvt to start after subtle, and for some reason echo "urxvt" >> ~/.xinitrc is just not cutting it. Using the :start hook and Subtlext we can simulate autostart like so:\r\n\r\n\r\non :start do\r\n Subtlext::Subtle.spawn "urxvt"\r\nend\r\n
- How can I use subtle without numpad?Per default subtle uses the numpad, because it's easier to remind the different postions when you can see them. Generally this is just a suggestion, it's up to you to change the grabs to your needs - any keys will work. \r\n\r\nKeys that also have proven to work well are q-w-e, a-s-d and y-x-c:\r\n\r\ngrab "W-q", [ :top_left, :top_left66, :top_left33 ]\r\ngrab "W-w", [ :top, :top66, :top33 ]\r\ngrab "W-e", [ :top_right, :top_right66, :top_right33 ]\r\ngrab "W-a", [ :left, :left66, :left33 ]\r\ngrab "W-s", [ :center, :center66, :center33 ]\r\ngrab "W-d", [ :right, :right66, :right33 ]\r\n\r\n# QWERTZ\r\ngrab "W-y", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\n# QWERTY\r\ngrab "W-z", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\ngrab "W-x", [ :bottom, :bottom66, :bottom33 ]\r\ngrab "W-c", [ :bottom_right, :bottom_right66, :bottom_right33 ]\r\n\r\n\r\n\r\nYou can find more about assigning keys here.
- How do I tag console based programs?Generally subtle can apply tags based on the {{color(#0000ff, WM_NAME)}} and both {{color(#ff0000, WM_CLASS)}} components. Console based programs like irssi can be started like this and will change the {{color(#0000ff, WM_NAME)}} of the terminal:\r\n\r\nurxvt -e irssi\r\n\r\nInspecting the terminal with xprop{{color(#0000ff, WM_NAME)}}(STRING) = "irssi"\r\n{{color(#ff0000, WM_CLASS)}}(STRING) = {{color(#aa0000, "urxvt")}}, {{color(#ff00ff, "URxvt")}}\r\n\r\nSo if we want to tag this window there are some things that should be considered:\r\n\r\n* irssi updates the {{color(#0000ff, WM_NAME)}} only\r\n* Tagging matches per default both {{color(#ff0000, WM_CLASS)}} components ({{color(#aa0000, instance)}} and {{color(#ff00ff, class)}} name)\r\n* Tags are applied when a window is mapped - that is before the terminal launches irssi safely tag it's better to change the {{color(#aa0000, instance)}} name of the terminal like this:\r\n\r\nurxvt -name irssi -e irssi\r\n\r\nThis results in following (via xprop{{color(#0000ff, WM_NAME)}}(STRING) = "irssi"\r\n{{color(#ff0000, WM_CLASS)}}(STRING) = {{color(#aa0000, "irssi")}}, {{color(#ff00ff, "URxvt")}}\r\n\r\nA tag for this could be:\r\n\r\ntag "irssi" do\r\n match :instance => "irssi"\r\nend\r\n\r\nPlease keep in mind, that the {{color(#ff0000, WM_CLASS)}} {{color(#ff00ff, class)}} name is still URxvt and will match other tags too. To avoid that there is the exclude match, it works similar to the normal match but excludes certain windows:\r\n\r\ntag "terms" do\r\n exclude :instance => "irssi"\r\nend

Subtle matches the {{color(#ff0000, WM_NAME)}} and the {{color(#0000ff, WM_CLASS)}} property of a window and not the title. This to ensure the match is correct. \r\nThere are several ways to get these values, here are the most common:\r\n\r\n* xprop: Just select the window and have a look for the WM_CLASS line which usually look like this:\r\n\r\np{class:pre}. WM_CLASS(STRING) = "{{color(#ff0000, urxvt)}}", "{{color(#0000ff, URxvt)}}")\r\n\r\n* subtler: Run subtler cl and look for the matching line:\r\n\r\np{class:pre}. 0x800007 * 1 1020x374 2 1 -- {{color(#ff0000, urxvt)}} ({{color(#0000ff,URxvt)}})¶

AWT_TOOLKIT=MToolkit program_JAVA_AWT_WM_NONREPARENTING=1 programHow do I run a java program?
Java expects a certain behaviour (reparenting of client windows) of a window manager which is not part of any standard, therefore some Java programs just show a white canvas.\r\n\r\nIf this happens just try to start your program like this:\r\n\r\nAWT_TOOLKIT=MToolkit program
\r\n\r\nThis changes the default tookit of Java to MToolkit, which is known to work with non-reparenting windows managers like subtle.

There are several way how to start a certain programm, here are the most common:\r\n\r\n* Start your program via your $HOME/.xinitrc:\r\n\r\n<pre><code class="ruby">\r\nsubtle &\r\nPID=$!\r\nsleep 2\r\nurxvt\r\nwait $PID\r\n</code></pre>\r\n\r\n* Start your program via [[grabs]]:\r\n\r\n<pre><code class="ruby">\r\n"A-x" => "urxvt"\r\n</code></pre>\r\n\r\nAdditionally there are many launchers available like "dmenu":http://tools.suckless.org/dmenu and there is even a launcher especially designed for [[subtle]], you can find it in "subtle-contrib":http://subforge.org/projects/subtle-contrib/wiki#Launcher.\r\n

h2. Why does program XYZ appears/turns as/to a gray canvas?
Generally, this happens, when a program needs a specific aspect ratio and [[subtle]] sets a gravity that violates this. Windows can tell the window manager about this kind of preferences via their size hints and [[subtle]] can honor those.\r\n\r\nThere are two possible ways:\r\n\r\n# Enable size hints globally with the _:resize_ option\r\n <pre>{{hide}}<code class="ruby">set :resize, true</code></pre>\r\n# Enable this per program via [[tagging|tag]]\r\n <pre>{{hide}}<code class="ruby">tag "name"\r\n match "name"\r\n resize true\r\nend

h2. How do I run a java program?
"Java":http://java.com *expects* a certain behaviour (_reparenting of client windows_) of a window manager which is not part of any standard, therefore some "Java":http://java.com programs just show a white canvas.\r\n\r\nIf this happens just try to start your program like this:\r\n\r\n<pre><code class="shell">AWT_TOOLKIT=MToolkit program</code></pre>\r\n\r\nThis changes the default tookit of "Java":http://java.com to MToolkit, which is known to work with non-reparenting windows managers like [[subtle]]. Depending on your "OpenJDK":http://openjdk.java.net version and your architecture this may either lead to a segmentation fault or your "OpenJDK":http://openjdk.java.net just has no support for *MToolkit*. In this case check if your distribution has applied a patch for this issue which allows something like this to change the default behaviour:\r\n\r\n<pre><code class="shell">_JAVA_AWT_WM_NONREPARENTING=1 program</code></pre>\r\n\r\nIn case both doesn't work there is a third option: The JDK internally uses a hardcoded list of window managers that are non-reparenting, the "suckless":http://suckless.org guys made the tool "wmname":http://tools.suckless.org/wmname to change the name of the wm and just lie to Java. \r\n\r\nGenerally this problem is really long lasting, see here: \r\n\r\nhttp://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6511454\r\nhttp://bugs.debian.org/cgi-bin/bugreport.cgi?bug=508650\r\n\r\n
h2. How do I set a wallpaper in subtle?
On start, [[subtle]] sets a background color (_if set_) to the root window and therefore *overwrites* any root pixmap set before. To avoid this, you just need to comment out the *&#58;background* line from your config.\r\n\r\n[[subtle]] itself has no and will never have either an autostart or way to set a wallpaper directly. Normally you just want to setup your X session and and not [[subtle]]. Your _~/.xinitrc_ is the right place for stuff like this.\r\n\r\nA background can easily set with a tool like "feh":http://linuxbrit.co.uk/software/feh/.
h2. How can I use subtle without numpad?
Per default [[subtle]] uses the numpad, because it's easier to remind the different postions when you can see them. Generally this is just a suggestion, it's up to you to change the grabs to your needs - any keys will work. \r\n\r\nKeys that also have proven to work well are *q-w-e*, *a-s-d* and *y-x-c*:\r\n\r\n<pre>{{hide}}<code class="ruby">grab "W-q", [ :top_left, :top_left66, :top_left33 ]\r\ngrab "W-w", [ :top, :top66, :top33 ]\r\ngrab "W-e", [ :top_right, :top_right66, :top_right33 ]\r\ngrab "W-a", [ :left, :left66, :left33 ]\r\ngrab "W-s", [ :center, :center66, :center33 ]\r\ngrab "W-d", [ :right, :right66, :right33 ]\r\n\r\n# QWERTZ\r\ngrab "W-y", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\n# QWERTY\r\ngrab "W-z", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\ngrab "W-x", [ :bottom, :bottom66, :bottom33 ]\r\ngrab "W-c", [ :bottom_right, :bottom_right66, :bottom_right33 ]\r\n</code></pre>\r\n\r\n\r\nYou can find more about assigning keys [[Grabs|here]].
h2. How do I move program xyz to view abc?

h2. What is required for the volume sublet?
The volume [[sublets|sublet]] uses @/dev/mixer@ to set/get the volume levels, which is an older interface introduced with "OSS":http://www.opensound.com/ and still available via "ALSA OSS emulation":http://www.alsa-project.org/. Apparently, newer kernels refuse to autoload that module anymore and you need to load it manually or via any init file.\r\n\r\n{{info(Please check to the docs of your distribution how to do it.)}}\r\n\r\n<pre><code>modprobe snd_mixer_oss</code></pre>\r\n\r\n{{warn(Following explanation is technical!)}}\r\n\r\nThe [[sublets|sublet]] needs a way to access a mixer without any asynchronous callbacks. The reason for that is that [[subtle]] is single-threaded and can't use a dedicated thread to wait for the reply, but the APIs of "ALSA":http://www.alsa-project.org/ and "PulseAudio":http://pulseaudio.org are both designed to be asynchronous. Normally event drivven is fine but it is troublesome when you can't use their mainloop.\r\n\r\nSince there is no way to add e.g. a control socket to the event main loop of [[subtle]], the @/dev/mixer@ approach is the only way and works for all sound systems.

There are many ways to change [[tagging|tags]] per runtime, common is to use either [[subtler]] or [[subtlext]].\r\n\r\nh2. subtler\r\n\r\n[[subtler]] can be used on the commandline:\r\n\r\n<pre>{{hide}}<code class="ruby">\r\nsubtler -ta tag #< Add new tag 'tag'\r\nsubtler -cT client tag #< Tag client 'client' with tag 'tag'\r\nsubtler -vT view tag #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2. subtlext\r\n\r\n[[subtlext]] requires basic "ruby":http://ruby-lang.org knowledge:\r\n\r\n<pre>{{hide}}<code class="ruby">require "subtle/subtlext"\r\n\r\ntag = Subtlext::Tag.new("tag").save #< Add new tag 'tag'\r\nSubtlext::Client["client"] + "tag" #< Tag client 'client' with tag 'tag'\r\nSubtlext::View["view"] + "tag" #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2.

Vitag\r\n\r\n"subtle-contrib":http://subforge.org/projects/subtle-contrib/wiki contains [[subtle-contrib:vitag|vitag]] a script to change the [[tagging|tags]] of windows and views with an editor.\r\n\r\nh3. Launcher\r\n\r\nThe "launcher":http://subforge.org/projects/subtle-contrib/wiki#Launcher uses quite the opposite way, instead of moving a window to a certain screen it just provides a way to launch a window directly on the right view with the correct [[tagging|tags]].\r\n\r\nh2. Stick\r\n\r\nMost of the time, setting the window to *stick* does the trick too. Stick just displays the window on all views until the mode is disabled again. This can be done with [[grabs]] (default keys: *W-s*) or with [[subtler]]. (click on the window: @subtler -cXS@)\r\n\r\n
h2. Where does sur store sublets and icons?
[[sur]] follows the "XDG Base Directory specifications":http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html to store data, which includes some base path for specific data types.\r\n\r\nFollowing paths are used:\r\n\r\n|_. Type |_. XDG path |_. Default path |\r\n| Sublets | @$XDG_DATA_HOME/subtle/sublets@ | @~/.local/share/subtle/sublets@ |\r\n| Icons | @$XDG_DATA_HOME/subtle(icons@ | @~/.local/share/subtle/icons@ |
h2. Why does program XYZ appears/turns as/to a gray canvas?
Generally, this happens, when a program needs a specific aspect ratio and [[subtle]] sets a gravity that violates this. Windows can tell the window manager about this kind of preferences via their size hints and [[subtle]] can honor those.\r\n\r\nThere are two possible ways:\r\n\r\n# Enable size hints globally with the _&#58;resize_ option\r\n <pre>{{hide}}<code class="ruby">set :resize, true</code></pre>\r\n# Enable this per program via [[tagging|tag]]\r\n <pre>{{hide}}<code class="ruby">tag "name" do\r\n match "name"\r\n resize true\r\nend</code></pre>\r\n\r\nbq. Note: This can happen with "Java":http://java.com too, see "here":http://subforge.org/ezfaq/show/subtle?faq_id=14 for more information.
h2. How can I use subtle without numpad?
Per default [[subtle]] uses the numpad, because it's easier to remind the different postions when you can see them. Generally this is just a suggestion, it's up to you to change the grabs to your needs - any keys will work. \r\n\r\nKeys that also have proven to work well are *q-w-e*, *a-s-d* and *y-x-c*:\r\n\r\n<pre>{{hide}}<code class="ruby">grab "W-q", [ :top_left, :top_left66, :top_left33 ]\r\ngrab "W-w", [ :top, :top66, :top33 ]\r\ngrab "W-e", [ :top_right, :top_right66, :top_right33 ]\r\ngrab "W-a", [ :left, :left66, :left33 ]\r\ngrab "W-s", [ :center, :center66, :center33 ]\r\ngrab "W-d", [ :right, :right66, :right33 ]\r\n\r\n# QWERTZ\r\ngrab "W-y", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\n# QWERTY\r\ngrab "W-z", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\ngrab "W-x", [ :bottom, :bottom66, :bottom33 ]\r\ngrab "W-c", [ :bottom_right, :bottom_right66, :bottom_right33 ]\r\n</code></pre>\r\n\r\n\r\nYou can find more about assigning keys [[Grabs|here]].
h2. What is the difference between ViewSwitch and ViewJump?
Boths keys change the [[view]] of the current active [[screens|screen]], but the behavior how they do that depends on if the system consists either of a single [[screens|screen]] or more.\r\n\r\nh2. Single screen\r\n\r\nHere both [[grabs]] do +exactly+ the same.\r\n\r\nh2. Multi screen\r\n\r\nHere the behavior depends of the select [[views|view]] is visible on another screen or not.\r\n\r\n* *ViewSwitch* either swaps the current [[views|view]] with the selected if it is visible on another [[screens|screen]] or just sets the selected [[views|view]] on current [[screens|screen]].\r\n* *ViewJump* either focus the selected [[views|view]] if it is visible on another screen or just sets the select view on current [[screens|screen]].

h2. Why did the volume sublet stop working after kernel update?
The volume [[sublets|sublet]] uses @/dev/mixer@ to set/get the volume levels, which is an older interface introduced with "OSS":http://www.opensound.com/ and still available via "ALSA OSS emulation":http://www.alsa-project.org/. Apparently, newer kernels refuse to autoload that module anymore and you need to load it manually or via any init file.\r\n\r\n{{info(Please check to the docs of your distribution how to do it.)}}\r\n\r\n{{warn(Following explanation is technical!)}}\r\n\r\nThe [[sublets|sublet]] needs a way to access a mixer without any asynchronous callbacks. The reason for that is that [[subtle]] is single-threaded and can't use a dedicated thread to wait for the reply, but the APIs of "ALSA":http://www.alsa-project.org/ and "PulseAudio":http://pulseaudio.org are both designed to be asynchronous. Normally event drivven is fine but it is troublesome when you can't use their mainloop.\r\n\r\nSince there is no way to add e.g. a control socket to the event main loop of [[subtle]], the @/dev/mixer@ approach is the only way and works for all sound systems.

h2. Is subtle a reparenting window manager?
*Nope*, [[subtle]] doesn't reparent windows and there is in fact *no* reason to do that. The layout in [[subtle]] is a really loose set, the only relation between a [[views|view]] and a [[client]] is [[tagging]] and this is checked on every [[views|view]] update.\r\n\r\nReparenting windows would require following additional steps, when a window is visible on a certain [[views|view]]:\r\n\r\n# Resize the [[views|view]] toplevel window to the size of the current [[screen]]\r\n# Reparent the [[client]] window to the toplevel window\r\n# Handle (ignore here) the generated expose and crossing events\r\n\r\nProbably sounds like not much overhead, but keep in mind this is just required because the developer of "Java":http://www.java.com/ and "Qt":http://qt.nokia.com/products/ cannot understand following line from the "ICCCM":http://tronche.com/gui/x/icccm/sec-4.html#s-4.2.1:\r\n\r\nbq. Clients must be aware that some window managers will reparent their top-level windows so that a window that was created as a child of the root will be displayed as a child of some window belonging to the window manager

Actually, I have no idea why setting the keyboard layout in your @xorg.conf@ isn't suffucient, but apparently you need to call *setxkbmap* in one of your startup files to set the keymap. My suggestion is to use the @~/.xinitrc@, because it is perfectly suited to setup Xorg and usually read.\r\n\r\nJust add something like this to your @~/.xinitrc@ *before* you start [[subtle]]: \r\n\r\n<pre><code>setxkbmap -layout 'de(nodeadkeys)'</code></pre>

For flash, browsers seem to use window instance and class names that doesn't match the browser values.

There are several way how to start a certain programm, here are the most common:\r\n\r\n* Start your program via your $HOME/.xinitrc:\r\n\r\n<pre><code class="ruby">\r\nsubtle &\r\nPID=$!\r\nsleep 2\r\nurxvt\r\nwait $PID\r\n</code></pre>\r\n\r\n* Start your program via [[grabs]]:\r\n\r\n<pre><code class="ruby">\r\n"A-x" => "urxvt"\r\n</code></pre>\r\n\r\nThere are many launchers available like "dmenu":http://tools.suckless.org/dmenu and there is even a launcher especially designed for [[subtle]], you can find it in [[subtle-contrib:Launcher|here]].\r\n
h2. How do I tag gimp?
[[Tagging]] "GIMP":http://gimp.org can be nasty, because the current version (2.6) uses inconsistent window names and roles. The window roles are fixed in the current development snapshot and will hopefully find their way into the 2.8 release.\r\n\r\nhttps://bugzilla.gnome.org/show_bug.cgi?id=645456
h2. How do I set a wallpaper in subtle?
On start, [[subtle]] sets a background color (_if set_) to the root window and therefore *overwrites* any root pixmap set before. To avoid this, you just need to comment out the *&#58;background* line from your config.\r\n\r\n[[subtle]] itself has no and will never have either an autostart or way to set a wallpaper directly. Normally you just want to setup your X session and and not [[subtle]]. Your _~/.xinitrc_ is the right place for stuff like this.\r\n\r\nA background can easily set with a tool like "feh":http://linuxbrit.co.uk/software/feh/.
h2. Why don't my grabs work with xyz keyboard layout?
Actually, I have no idea why setting the keyboard layout in your @xorg.conf@ isn't suffucient, but apparently you need to call *setxkbmap* in one of your startup files to set the keymap. My suggestion is to use the @~/.xinitrc@, because it is perfectly suited to setup Xorg and usually read.\r\n\r\nJust add something like this to your @~/.xinitrc@ *before* you start [[subtle]]: \r\n\r\n<pre><code>setxkbmap -layout 'de(nodeadkeys)'</code></pre>
h2. How to match a GLFW window

h2. How can I manually delete a sublet?
[[Sublets]] usually consist of a *&#42;.rb* file, a *&#42;.spec* file and one or more icons. All these files can be found in their respective folder in @$XDG_DATA_HOME/subtle@ resp. @~/.local/share/subtle@. After deleting the [[sublets|sublet]] files the cache of [[sur]] needs to be updated or otherwise [[sur]] will think the [[sublets|sublet]] is still installed: @sur update -l@
h2. Where does sur store sublets and icons?
[[sur]] follows the "XDG Base Directory specifications":http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html to store data, which includes some base path for specific data types.\r\n\r\nFollowing paths are used:\r\n\r\n|_. Type |_. XDG path |_. Default path |\r\n| Sublets | @$XDG_DATA_HOME/subtle/sublets@ | @~/.local/share/subtle/sublets@ |\r\n| Icons | @$XDG_DATA_HOME/subtle(icons@ | @~/.local/share/subtle/icons@ |

h2. How do I run a program on startup/autostart?
Let's say you want "urxvt":http://software.schmorp.de/pkg/rxvt-unicode.html to start after [[subtle]], and for some reason @echo "urxvt" >> ~/.xinitrc@ is just not cutting it. Using the *&#58;start* hook and [[subtlext]] we can simulate autostart like so:\r\n\r\n<pre>{{hide}}<code class="ruby">\r\non :start do\r\n Subtlext::Subtle.spawn "urxvt"\r\nend\r\n</pre></code>
h2. Where is the output window of flash in fullscreen?
For flash, browsers seem to use window instance and class names that doesn't match the browser values. Therefore the windows will usually appear on the default view.\r\n\r\nFollowing names are currently in use:\r\n\r\n|_. Browser |_. Arch |_. WM_NAME |_. WM_CLASS |\r\n| Firefox <7.0.1 | all | <unknown> | "<unknown>", "<unknown>" |\r\n| Firefox >=7.0.1 | all | plugin-container | "plugin-container", "Plugin-container" |\r\n| Chromium | all | exe | "exe", "Exe" |\r\n| Opera | x86 | "operapluginwrapper" | "operapluginwrapper", "Operapluginwrapper" |\r\n| nspluginwrapper | x86_64 | "npviewer.bin" | "Npviewer.bin" |\r\n\r\nThe easiest way to avoid that is to add a [[tagging|tag]] that makes these windows sticky:\r\n\r\n<pre>{{hide}}<code class="ruby">tag "flash" do\r\n match "<unknown>|plugin-container|exe|operapluginwrapper|npviewer.bin"\r\n stick true\r\nend</code></pre>
h2. What is the difference between ViewSwitch and ViewJump?
Boths keys change the [[view]] of the current active [[screens|screen]], but the behavior how they do that depends on if the system consists either of a single [[screens|screen]] or more.\r\n\r\nh2. Single screen\r\n\r\nHere both [[grabs]] do +exactly+ the same.\r\n\r\nh2. Multi screen\r\n\r\nHere the behavior depends on if the selected [[views|view]] is visible on another [[screens|screen]] or not.\r\n\r\n* *ViewSwitch* either swaps the current [[views|view]] with the selected if it is visible on another [[screens|screen]] or just sets the selected [[views|view]] on current [[screens|screen]].\r\n* *ViewJump* either focus the selected [[views|view]] if it is visible on another [[screens|screen]] or just sets the select [[views|view]] on current [[screens|screen]].
h2. Why does program XYZ appears/turns as/to a gray canvas?
Generally, this happens, when a program needs a specific aspect ratio and [[subtle]] sets a gravity that violates this. Windows can tell the window manager about this kind of preferences via their size hints and [[subtle]] can honor those.\r\n\r\nThere are two possible ways:\r\n\r\n# Enable size hints globally with the _&#58;resize_ option\r\n <pre>{{hide}}<code class="ruby">set :resize, true</code></pre>\r\n# Enable this per program via [[tagging|tag]]\r\n <pre>{{hide}}<code class="ruby">tag "name" do\r\n match "name"\r\n resize true\r\nend</code></pre>\r\n\r\nbq. Note: This can happen with "Java":http://java.com too, see "here":http://subforge.org/ezfaq/show/subtle?faq_id=14 for more information.
h2. How do I run a Java program?
"Java":http://java.com *expects* a certain behaviour (_reparenting of client windows_) of a window manager which is not part of any standard, therefore some "Java":http://java.com programs just show a white canvas.\r\n\r\nIf this happens just try to start your program like this:\r\n\r\n<pre><code class="shell">AWT_TOOLKIT=MToolkit program</code></pre>\r\n\r\nThis changes the default tookit of "Java":http://java.com to _MToolkit_, which is known to work with non-reparenting windows managers like [[subtle]]. Depending on your "OpenJDK":http://openjdk.java.net version and your architecture this may either lead to a segmentation fault or your "OpenJDK":http://openjdk.java.net just has no support for *MToolkit*. In this case check if your distribution has applied a patch for this issue which allows something like this to change the default behaviour:\r\n\r\n<pre><code class="shell">_JAVA_AWT_WM_NONREPARENTING=1 program</code></pre>\r\n\r\nIn case both doesn't work there is a third option: "Java":http://java.com seems to use an internally hardcoded list of window managers that are non-reparenting, the "suckless":http://suckless.org guys made a tool ("wmname":http://tools.suckless.org/wmname) to change the name of the wm.\r\n\r\nSince r2520 [[subtle]] can do that for you, just enable the *&#58;wmname* option.\r\n\r\nGenerally this problem is really long lasting, see here: \r\n\r\nhttp://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6511454\r\nhttp://bugs.debian.org/cgi-bin/bugreport.cgi?bug=508650\r\n\r\nbq. Note: Many problems only affect the "JRE":http://www.oracle.com/technetwork/java/javase/downloads/index.html and can be avoided by using the "OpenJDK":http://openjdk.java.net.\r\n\r\n
h2. How do I tag console based programs?
When console based programs like "irssi":http://irssi.org are started with a terminal like @urxvt -e irssi@, they usually just change the *WM_NAME* of the terminal and per default, [[subtle]] uses both of the *WM_CLASS* values for tagging.\r\n\r\nThe problem about that is, that the [[tagging]] is normally done before the terminal really starts the desired app. To avoid that all better known terminals support the *-name* argument which changes the instance value (first string) of the *WM_CLASS*: @urxvt -name irssi -e irssi@\r\n\r\nAnother problem is that terminals retain their class value (second string) of the *WM_CLASS* and may match other [[tagging|tags]] like:\r\n\r\n<pre><code class="ruby">tag "terms" do\r\n match "urxvt"\r\nend</code></pre>\r\n\r\nThe common solution to bypass is this to use the :instance matcher, which just matches when for the specific instance value. So the easiest way to reliable match this client is a [[tagging|tag]] like this:\r\n\r\n<pre><code class="ruby">tag "irssi" do\r\n match :instance => "irssi"\r\nend</code></pre>\r\n\r\nFollowing table shows the *WM_NAME* and *WM_CLASS* output of "xprop":http://www.xfree86.org/current/xprop.1.html of the various combinations:\r\n\r\n|_. Command |_. WM_NAME |_. WM_CLASS |\r\n| urxvt | urxvt | urxvt, URxvt |\r\n| urxvt -e irssi | irssi | urxvt, URxvt |\r\n| urxvt -name irssi | urxvt | irssi, URxvt |\r\n| urxvt -name irssi -e irssi | irssi | irssi, URxvt |\r\n\r\nPlease have a look at the [[Tagging|tagging wiki page]] for more information.\r\n\r\n\r\n
h2. How can I use subtle without numpad?
Per default [[subtle]] uses the numpad, because it's easier to remind the different postions when you can see them. Generally this is just a suggestion, it's up to you to change the grabs to your needs - any keys will work. \r\n\r\nKeys that also have proven to work well are *q-w-e*, *a-s-d* and *y-x-c*:\r\n\r\n<pre>{{hide}}<code class="ruby">grab "W-q", [ :top_left, :top_left66, :top_left33 ]\r\ngrab "W-w", [ :top, :top66, :top33 ]\r\ngrab "W-e", [ :top_right, :top_right66, :top_right33 ]\r\ngrab "W-a", [ :left, :left66, :left33 ]\r\ngrab "W-s", [ :center, :center66, :center33 ]\r\ngrab "W-d", [ :right, :right66, :right33 ]\r\n\r\n# QWERTZ\r\ngrab "W-y", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\n# QWERTY\r\ngrab "W-z", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\ngrab "W-x", [ :bottom, :bottom66, :bottom33 ]\r\ngrab "W-c", [ :bottom_right, :bottom_right66, :bottom_right33 ]\r\n</code></pre>\r\n\r\n\r\nYou can find more about assigning keys [[Grabs|here]].
h2. How does subtle match clients?
[[subtle]] matches the {{color(#ff0000, WM_NAME)}} and the {{color(#0000ff, WM_CLASS)}} property of a window and not the title. This to ensure the match is correct. \r\nThere are several ways to get these values, here are the most common:\r\n\r\nSelect the window with "xprop":http://www.xfree86.org/current/xprop.1.htmland have a look for the {{color(#ff0000, WM_NAME)}} and {{color(#0000ff, WM_CLASS)}} lines which usually look like this:\r\n\r\n<pre><code class="bash">{{color(#0000ff, WM_NAME)}}(STRING) = "urxvt"\r\n{{color(#ff0000, WM_CLASS)}}(STRING) = {{color(#aa0000, "irssi")}}, {{color(#ff00ff, "URxvt")}}</code></pre>\r\n\r\nRun *[[subtler]] -cl* and look for the matching line:\r\n\r\n<pre><code class="bash">0x800007 * 1 1020x374 2 1 --- {{color(#ff0000, urxvt)}} ({{color(#0000ff,URxvt)}})</code></pre>
h2. Is subtle a reparenting window manager?
*Nope*, [[subtle]] doesn't reparent windows and there is in fact *no* reason to do that. The layout in [[subtle]] is a really loose set, the only relation between a [[views|view]] and a [[client]] is [[tagging]] and this is checked on every [[views|view]] update.\r\n\r\nReparenting windows would require following additional steps, when a window is visible on a certain [[views|view]]:\r\n\r\n# Resize the [[views|view]] toplevel window to the size of the current [[screen]]\r\n# Reparent the [[client]] window to the toplevel window\r\n# Handle (ignore here) the generated expose and crossing events\r\n\r\nProbably sounds like not much overhead, but keep in mind this is just required because the developer of "Java":http://www.java.com/ and "Qt":http://qt.nokia.com/products/ cannot understand following line from the "ICCCM":http://tronche.com/gui/x/icccm/sec-4.html#s-4.2.1:\r\n\r\nbq. Clients must be aware that some window managers will reparent their top-level windows so that a window that was created as a child of the root will be displayed as a child of some window belonging to the window manager
h2. How do I move a program to another view?
Placement in [[subtle]] is +strict+ and completely done via [[tagging]]. There are many ways to change [[tagging|tags]] per runtime, common is to use either [[subtler]] or [[subtlext]].\r\n\r\nh2. subtler\r\n\r\n[[subtler]] can be used on the commandline:\r\n\r\n<pre>{{hide}}<code class="ruby">\r\nsubtler -ta tag #< Add new tag 'tag'\r\nsubtler -cT client tag #< Tag client 'client' with tag 'tag'\r\nsubtler -vT view tag #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2. subtlext\r\n\r\n[[subtlext]] requires basic "ruby":http://ruby-lang.org knowledge:\r\n\r\n<pre>{{hide}}<code class="ruby">require "subtle/subtlext"\r\n\r\ntag = Subtlext::Tag.new("tag").save #< Add new tag 'tag'\r\nSubtlext::Client["client"] + "tag" #< Tag client 'client' with tag 'tag'\r\nSubtlext::View["view"] + "tag" #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2. Snippets\r\n\r\nThe [[snippets]] wiki page includes examples how to [[snippets#Move-windows|move to another view]].\r\n\r\nh2. Contrib\r\n\r\nh3. Vitag\r\n\r\n"subtle-contrib":http://subforge.org/projects/subtle-contrib/wiki contains [[subtle-contrib:vitag|vitag]] a script to change the [[tagging|tags]] of windows and views with an editor.\r\n\r\nh3. Launcher\r\n\r\nThe "launcher":http://subforge.org/projects/subtle-contrib/wiki#Launcher uses quite the opposite way, instead of moving a window to a certain screen it just provides a way to launch a window directly on the right view with the correct [[tagging|tags]].\r\n\r\nh2. Stick\r\n\r\nMost of the time, setting the window to *stick* does the trick too. Stick just displays the window on all views until the mode is disabled again. This can be done with [[grabs]] (default keys: *W-s*) or with [[subtler]]. (click on the window: @subtler -cXS@)\r\n\r\n
h2. What is required for the volume sublet?
The volume [[sublets|sublet]] uses @/dev/mixer@ to set/get the volume levels, which is an older interface introduced with "OSS":http://www.opensound.com/ and still available via "ALSA OSS emulation":http://www.alsa-project.org/. Apparently, newer kernels refuse to autoload that module anymore and you need to load it manually or via any init file.\r\n\r\n{{info(Please check to the docs of your distribution how to do it.)}}\r\n\r\n<pre><code>modprobe snd_mixer_oss</code></pre>\r\n\r\n{{warn(Following explanation is technical!)}}\r\n\r\nThe [[sublets|sublet]] needs a way to access a mixer without any asynchronous callbacks. The reason for that is that [[subtle]] is single-threaded and can't use a dedicated thread to wait for the reply, but the APIs of "ALSA":http://www.alsa-project.org/ and "PulseAudio":http://pulseaudio.org are both designed to be asynchronous. Normally event drivven is fine but it is troublesome when you can't use their mainloop.\r\n\r\nSince there is no way to add e.g. a control socket to the event main loop of [[subtle]], the @/dev/mixer@ approach is the only way and works for all sound systems.

h2. What is required for the volume sublet?
The volume [[sublets|sublet]] uses @/dev/mixer@ to set/get the volume levels, which is an older interface introduced with "OSS":http://www.opensound.com/ and still available via "ALSA OSS emulation":http://www.alsa-project.org/. Apparently, newer kernels refuse to autoload that module anymore and you need to load it manually or via any init file.\r\n\r\n{{info(Please check to the docs of your distribution how to do it.)}}\r\n\r\n<pre><code>modprobe snd_mixer_oss</code></pre>\r\n\r\n{{warn(Following explanation is technical!)}}\r\n\r\nThe [[sublets|sublet]] needs a way to access a mixer without any asynchronous callbacks. The reason for that is that [[subtle]] is single-threaded and can't use a dedicated thread to wait for the reply, but the APIs of "ALSA":http://www.alsa-project.org/ and "PulseAudio":http://pulseaudio.org are both designed to be asynchronous. Normally event drivven is fine but it is troublesome when you can't use their mainloop.\r\n\r\nSince there is no way to add e.g. a control socket to the event main loop of [[subtle]], the @/dev/mixer@ approach is the only way and works for all sound systems.

h2. How can I use subtle without numpad?
Per default [[subtle]] uses the numpad, because it's easier to remind the different postions when you can see them. Generally this is just a suggestion, it's up to you to change the grabs to your needs - any keys will work. \r\n\r\nKeys that also have proven to work well are *q-w-e*, *a-s-d* and *y-x-c*:\r\n\r\n<pre>{{hide}}<code class="ruby">grab "W-q", [ :top_left, :top_left66, :top_left33 ]\r\ngrab "W-w", [ :top, :top66, :top33 ]\r\ngrab "W-e", [ :top_right, :top_right66, :top_right33 ]\r\ngrab "W-a", [ :left, :left66, :left33 ]\r\ngrab "W-s", [ :center, :center66, :center33 ]\r\ngrab "W-d", [ :right, :right66, :right33 ]\r\n\r\n# QWERTZ\r\ngrab "W-y", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\n# QWERTY\r\ngrab "W-z", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\ngrab "W-x", [ :bottom, :bottom66, :bottom33 ]\r\ngrab "W-c", [ :bottom_right, :bottom_right66, :bottom_right33 ]\r\n</code></pre>\r\n\r\n\r\nYou can find more about assigning keys [[Grabs|here]].

h2. Why does subtle cause to many wakeups?
The wakeups are caused by a "Ruby":http://ruby-lang.org internal polling thread that runs every 10ms to schedule/handle other threads and signals.

h2. How do I tag gimp?
[[Tagging]] "GIMP":http://gimp.org can be nasty, because the current version (2.6) uses inconsistent window names and roles.

There are many ways to change [[tagging|tags]] per runtime, common is to use either [[subtler]] or [[subtlext]].\r\n\r\nh2. subtler\r\n\r\n[[subtler]] can be used on the commandline:\r\n\r\n<pre>{{hide}}<code class="ruby">\r\nsubtler -ta tag #< Add new tag 'tag'\r\nsubtler -cT client tag #< Tag client 'client' with tag 'tag'\r\nsubtler -vT view tag #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2. subtlext\r\n\r\n[[subtlext]] requires basic "ruby":http://ruby-lang.org knowledge:\r\n\r\n<pre>{{hide}}<code class="ruby">require "subtle/subtlext"\r\n\r\ntag = Subtlext::Tag.new("tag").save #< Add new tag 'tag'\r\nSubtlext::Client["client"] + "tag" #< Tag client 'client' with tag 'tag'\r\nSubtlext::View["view"] + "tag" #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2. Snippets\r\n\r\nThe [[snippets]] wiki page includes examples how to [[snippets#Move-windows|move to another view]].\r\n\r\nh2. Contrib\r\n\r\nh3. Vitag\r\n\r\n"subtle-contrib":http://subforge.org/projects/subtle-contrib/wiki contains [[subtle-contrib:vitag|vitag]] a script to change the [[tagging|tags]] of windows and views with an editor.\r\n\r\nh3. Launcher\r\n\r\nThe "launcher":http://subforge.org/projects/subtle-contrib/wiki#Launcher uses quite the opposite way, instead of moving a window to a certain screen it just provides a way to launch a window directly on the right view with the correct [[tagging|tags]].\r\n\r\nh2. Stick\r\n\r\nMost of the time, setting the window to *stick* does the trick too. Stick just displays the window on all views until the mode is disabled again. This can be done with [[grabs]] (default keys: *W-s*) or with [[subtler]]. (click on the window: @subtler -cXS@)\r\n\r\n
h2. How do I start a program?
There are several way how to start a certain programm, here are the most common:\r\n\r\n* Start your program via your $HOME/.xinitrc:\r\n\r\n<pre><code class="ruby">\r\nsubtle &\r\nPID=$!\r\nsleep 2\r\nurxvt\r\nwait $PID\r\n</code></pre>\r\n\r\n* Start your program via [[grabs]]:\r\n\r\n<pre><code class="ruby">\r\n"A-x" => "urxvt"\r\n</code></pre>\r\n\r\nThere are many launchers available like "dmenu":http://tools.suckless.org/dmenu and there is even a launcher especially designed for [[subtle]], you can find it in [[subtle-contrib:Launcher|here]].\r\n
h2. How do I tag console based programs?
When console based programs like "irssi":http://irssi.org are started with a terminal like @urxvt -e irssi@, they usually just change the *WM_NAME* of the terminal and per default, [[subtle]] just uses both of the {{color(#ff0000, WM_CLASS)}} values for tagging.\r\n\r\nThe problem about that is, that the [[tagging]] is normally done before the terminal really starts the desired app. To avoid that all better known terminals support the *-name* argument which changes the instance value (first string) of the *WM_CLASS*: @urxvt -name irssi -e irssi@\r\n\r\nAnother problem is that terminals retain their class value (second string) of the {{color(#ff0000, WM_CLASS)}} and may match other [[tagging|tags]].\r\n\r\nThe common solution to bypass is this to use the :instance matcher, which just matches when for the specific instance value. \r\n\r\nFollowing table shows the *WM_NAME* and *WM_CLASS* output of "xprop":http://www.xfree86.org/current/xprop.1.html of the various combinations:\r\n\r\n|_. Command |_. WM_NAME |_.

h2. Why did the volume sublet stop working after kernel update?
The volume [[sublets|sublet]] uses @/dev/mixer@ to set/get the volume levels, which is an older interface introduced with "OSS":http://www.opensound.com/ and still available via "ALSA OSS emulation":http://www.alsa-project.org/. Apparently, newer kernels refuse to autoload that module anymore and you need to load it manually or via any init file.\r\n\r\n{{info(Please check to the docs of your distribution how to do it.)}}\r\n\r\n{{warn(Following explanation is technical!)}}\r\n\r\nThe [[sublets|sublet]] needs a way to access a mixer without any asynchronous callbacks. The reason for that is that [[subtle]] is single-threaded and can't use a dedicated thread to wait for the reply, but the APIs of "ALSA":http://www.alsa-project.org/ and "PulseAudio":http://pulseaudio.org are both designed to be asynchronous. Normally event drivven is fine but it is troublesome when you can't use their mainloop.\r\n\r\nSince there is no way to add e.g. a control socket to the event main loop of [[subtle]], the @/dev/mixer@ approach is the only way and works for all sound systems.

h2. Is subtle a reparenting window manager?
*Nope*, [[subtle]] doesn't reparent windows and there is in fact *no* reason to do that. The layout in [[subtle]] is a really loose set, the only relation between a [[views|view]] and a [[client]] is [[tagging]] and this is checked on every [[views|view]] update.\r\n\r\nReparenting windows would require following additional steps, when a window is visible on a certain [[views|view]]:\r\n\r\n# Resize the [[views|view]] toplevel window to the size of the current [[screen]]\r\n# Reparent the [[client]] window to the toplevel window\r\n# Handle (ignore here) the generated expose and crossing events\r\n\r\nProbably sounds like not much overhead, but keep in mind this is just required because the developer of "Java":http://www.java.com/ and "Qt":http://qt.nokia.com/products/ cannot understand following line from the "ICCCM":http://tronche.com/gui/x/icccm/sec-4.html#s-4.2.1:\r\n\r\nbq. Clients must be aware that some window managers will reparent their top-level windows so that a window that was created as a child of the root will be displayed as a child of some window belonging to the window manager

Actually, I have no idea why setting the keyboard layout in your @xorg.conf@ isn't suffucient, but apparently you need to call *setxkbmap* in one of your startup files to set the keymap. My suggestion is to use the @~/.xinitrc@, because it is perfectly suited to setup Xorg and usually read.\r\n\r\nJust add something like this to your @~/.xinitrc@ *before* you start [[subtle]]: \r\n\r\n<pre><code>setxkbmap -layout 'de(nodeadkeys)'</code></pre>

For flash, browsers seem to use window instance and class names that doesn't match the browser values.

On start, [[subtle]] sets a background color (_if set_) to the root window and therefore *overwrites* any root pixmap set before. To avoid this, you just need to comment out the *&#58;background* line from your config.\r\n\r\n[[subtle]] itself has no and will never have either an autostart or way to set a wallpaper directly. Normally you just want to setup your X session and and not [[subtle]]. Your _~/.xinitrc_ is the right place for stuff like this.\r\n\r\nA background can easily set with a tool like "feh":http://linuxbrit.co.uk/software/feh/.

h2. How can I manually delete a sublet?
[[Sublets]] usually consist of a *&#42;.rb* file, a *&#42;.spec* file and one or more icons. All these files can be found in their respective folder in @$XDG_DATA_HOME/subtle@ resp. @~/.local/share/subtle@. After deleting the [[sublets|sublet]] files the cache of [[sur]] needs to be updated or otherwise [[sur]] will think the [[sublets|sublet]] is still installed: @sur update -l@
h2. Where does sur store sublets and icons?
[[sur]] follows the "XDG Base Directory specifications":http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html to store data, which includes some base path for specific data types.\r\n\r\nFollowing paths are used:\r\n\r\n|_.

h2. What is the difference between ViewSwitch and ViewJump?
Boths keys change the [[view]] of the current active [[screens|screen]], but the behavior how they do that depends on if the system consists either of a single [[screens|screen]] or more.\r\n\r\nh2. Single screen\r\n\r\nHere both [[grabs]] do +exactly+ the same.\r\n\r\nh2. Multi screen\r\n\r\nHere the behavior depends on if the selected [[views|view]] is visible on another [[screens|screen]] or not.\r\n\r\n* *ViewSwitch* either swaps the current [[views|view]] with the selected if it is visible on another [[screens|screen]] or just sets the selected [[views|view]] on current [[screens|screen]].\r\n* *ViewJump* either focus the selected [[views|view]] if it is visible on another [[screens|screen]] or just sets the select [[views|view]] on current [[screens|screen]].
h2. Why does program XYZ appears/turns as/to a gray canvas?
Generally, this happens, when a program needs a specific aspect ratio and [[subtle]] sets a gravity that violates this. Windows can tell the window manager about this kind of preferences via their size hints and [[subtle]] can honor those.\r\n\r\nThere are two possible ways:\r\n\r\n# Enable size hints globally with the _&#58;resize_ option\r\n <pre>{{hide}}<code class="ruby">set :resize, true</code></pre>\r\n# Enable this per program via [[tagging|tag]]\r\n <pre>{{hide}}<code class="ruby">tag "name" do\r\n match "name"\r\n resize true\r\nend</code></pre>\r\n\r\nbq.

"Java":http://java.com *expects* a certain behaviour (_reparenting of client windows_) of a window manager which is not part of any standard, therefore some "Java":http://java.com programs just show a white canvas.\r\n\r\nIf this happens just try to start your program like this:\r\n\r\n<pre><code class="shell">AWT_TOOLKIT=MToolkit program</code></pre>\r\n\r\nThis changes the default tookit of "Java":http://java.com to _MToolkit_, which is known to work with non-reparenting windows managers like [[subtle]]. Depending on your "OpenJDK":http://openjdk.java.net version and your architecture this may either lead to a segmentation fault or your "OpenJDK":http://openjdk.java.net just has no support for *MToolkit*. In this case check if your distribution has applied a patch for this issue which allows something like this to change the default behaviour:\r\n\r\n<pre><code class="shell">_JAVA_AWT_WM_NONREPARENTING=1 program</code></pre>\r\n\r\nIn case both doesn't work there is a third option: "Java":http://java.com seems to use an internally hardcoded list of window managers that are non-reparenting, the "suckless":http://suckless.org guys made a tool ("wmname":http://tools.suckless.org/wmname) to change the name of the wm.\r\n\r\nSince r2520 [[subtle]] can do that for you, just enable the *&#58;wmname* option.\r\n\r\nGenerally this problem is really long lasting, see here: \r\n\r\nhttp://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6511454\r\nhttp://bugs.debian.org/cgi-bin/bugreport.cgi?bug=508650\r\n\r\nbq. Note: Many problems only affect the "JRE":http://www.oracle.com/technetwork/java/javase/downloads/index.html and can be avoided by using the "OpenJDK":http://openjdk.java.net.\r\n\r\n
h2. How do I tag console based programs?
When console based programs like "irssi":http://irssi.org are started with a terminal like @urxvt -e irssi@, they usually just change the *WM_NAME* of the terminal and per default, [[subtle]] uses both of the *WM_CLASS* values for tagging.\r\n\r\nThe problem about that is, that the [[tagging]] is normally done before the terminal really starts the desired app. To avoid that all better known terminals support the *-name* argument which changes the instance value (first string) of the *WM_CLASS*: @urxvt -name irssi -e irssi@\r\n\r\nAnother problem is that terminals retain their class value (second string) of the *WM_CLASS* and may match other [[tagging|tags]] like:\r\n\r\n<pre><code class="ruby">tag "terms" do\r\n match "urxvt"\r\nend</code></pre>\r\n\r\nThe common solution to bypass is this to use the :instance matcher, which just matches when for the specific instance value. So the easiest way to reliable match this client is a [[tagging|tag]] like this:\r\n\r\n<pre><code class="ruby">tag "irssi" do\r\n match :instance => "irssi"\r\nend</code></pre>\r\n\r\nFollowing table shows the *WM_NAME* and *WM_CLASS* output of "xprop":http://www.xfree86.org/current/xprop.1.html of the various combinations:\r\n\r\n|_. Command |_. WM_NAME |_. WM_CLASS |\r\n| urxvt | urxvt | urxvt, URxvt |\r\n| urxvt -e irssi | irssi | urxvt, URxvt |\r\n| urxvt -name irssi | urxvt | irssi, URxvt |\r\n| urxvt -name irssi -e irssi | irssi | irssi, URxvt |\r\n\r\nPlease have a look at the [[Tagging|tagging wiki page]] for more information.\r\n\r\n\r\n
h2. How can I use subtle without numpad?
Per default [[subtle]] uses the numpad, because it's easier to remind the different postions when you can see them. Generally this is just a suggestion, it's up to you to change the grabs to your needs - any keys will work. \r\n\r\nKeys that also have proven to work well are *q-w-e*, *a-s-d* and *y-x-c*:\r\n\r\n<pre>{{hide}}<code class="ruby">grab "W-q", [ :top_left, :top_left66, :top_left33 ]\r\ngrab "W-w", [ :top, :top66, :top33 ]\r\ngrab "W-e", [ :top_right, :top_right66, :top_right33 ]\r\ngrab "W-a", [ :left, :left66, :left33 ]\r\ngrab "W-s", [ :center, :center66, :center33 ]\r\ngrab "W-d", [ :right, :right66, :right33 ]\r\n\r\n# QWERTZ\r\ngrab "W-y", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\n# QWERTY\r\ngrab "W-z", [ :bottom_left, :bottom_left66, :bottom_left33 ]\r\n\r\ngrab "W-x", [ :bottom, :bottom66, :bottom33 ]\r\ngrab "W-c", [ :bottom_right, :bottom_right66, :bottom_right33 ]\r\n</code></pre>\r\n\r\n\r\nYou can find more about assigning keys [[Grabs|here]].
h2. How does subtle match clients?
[[subtle]] matches the {{color(#ff0000, WM_NAME)}} and the {{color(#0000ff, WM_CLASS)}} property of a window and not the title. This to ensure the match is correct. \r\nThere are several ways to get these values, here are the most common:\r\n\r\nSelect the window with "xprop":http://www.xfree86.org/current/xprop.1.htmland have a look for the {{color(#ff0000, WM_NAME)}} and {{color(#0000ff, WM_CLASS)}} lines which usually look like this:\r\n\r\n<pre><code class="bash">{{color(#0000ff, WM_NAME)}}(STRING) = "urxvt"\r\n{{color(#ff0000, WM_CLASS)}}(STRING) = {{color(#aa0000, "irssi")}}, {{color(#ff00ff, "URxvt")}}</code></pre>\r\n\r\nRun *[[subtler]] -cl* and look for the matching line:\r\n\r\n<pre><code class="bash">0x800007 * 1 1020x374 2 1 --- {{color(#ff0000, urxvt)}} ({{color(#0000ff,URxvt)}})</code></pre>
h2. Is subtle a reparenting window manager?
*Nope*, [[subtle]] doesn't reparent windows and there is in fact *no* reason to do that. The layout in [[subtle]] is a really loose set, the only relation between a [[views|view]] and a [[client]] is [[tagging]] and this is checked on every [[views|view]] update.\r\n\r\nReparenting windows would require following additional steps, when a window is visible on a certain [[views|view]]:\r\n\r\n# Resize the [[views|view]] toplevel window to the size of the current [[screen]]\r\n# Reparent the [[client]] window to the toplevel window\r\n# Handle (ignore here) the generated expose and crossing events\r\n\r\nProbably sounds like not much overhead, but keep in mind this is just required because the developer of "Java":http://www.java.com/ and "Qt":http://qt.nokia.com/products/ cannot understand following line from the "ICCCM":http://tronche.com/gui/x/icccm/sec-4.html#s-4.2.1:\r\n\r\nbq. Clients must be aware that some window managers will reparent their top-level windows so that a window that was created as a child of the root will be displayed as a child of some window belonging to the window manager
h2. How do I move a program to another view?
Placement in [[subtle]] is +strict+ and completely done via [[tagging]]. There are many ways to change [[tagging|tags]] per runtime, common is to use either [[subtler]] or [[subtlext]].\r\n\r\nh2. subtler\r\n\r\n[[subtler]] can be used on the commandline:\r\n\r\n<pre>{{hide}}<code class="ruby">\r\nsubtler -ta tag #< Add new tag 'tag'\r\nsubtler -cT client tag #< Tag client 'client' with tag 'tag'\r\nsubtler -vT view tag #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2. subtlext\r\n\r\n[[subtlext]] requires basic "ruby":http://ruby-lang.org knowledge:\r\n\r\n<pre>{{hide}}<code class="ruby">require "subtle/subtlext"\r\n\r\ntag = Subtlext::Tag.new("tag").save #< Add new tag 'tag'\r\nSubtlext::Client["client"] + "tag" #< Tag client 'client' with tag 'tag'\r\nSubtlext::View["view"] + "tag" #< Tag view 'view' with tag 'tag'\r\n</code></pre>\r\n\r\nh2. Snippets\r\n\r\nThe [[snippets]] wiki page includes examples how to [[snippets#Move-windows|move to another view]].\r\n\r\nh2. Contrib\r\n\r\nh3. Vitag\r\n\r\n"subtle-contrib":http://subforge.org/projects/subtle-contrib/wiki contains [[subtle-contrib:vitag|vitag]] a script to change the [[tagging|tags]] of windows and views with an editor.\r\n\r\nh3. Launcher\r\n\r\nThe "launcher":http://subforge.org/projects/subtle-contrib/wiki#Launcher uses quite the opposite way, instead of moving a window to a certain screen it just provides a way to launch a window directly on the right view with the correct [[tagging|tags]].\r\n\r\nh2. Stick\r\n\r\nMost of the time, setting the window to *stick* does the trick too. Stick just displays the window on all views until the mode is disabled again. This can be done with [[grabs]] (default keys: *W-s*) or with [[subtler]]. (click on the window: @subtler -cXS@)\r\n\r\n
h2. What is required for the volume sublet?
The volume [[sublets|sublet]] uses @/dev/mixer@ to set/get the volume levels, which is an older interface introduced with "OSS":http://www.opensound.com/ and still available via "ALSA OSS emulation":http://www.alsa-project.org/. Apparently, newer kernels refuse to autoload that module anymore and you need to load it manually or via any init file.\r\n\r\n{{info(Please check to the docs of your distribution how to do it.)}}\r\n\r\n<pre><code>modprobe snd_mixer_oss</code></pre>\r\n\r\n{{warn(Following explanation is technical!)}}\r\n\r\nThe [[sublets|sublet]] needs a way to access a mixer without any asynchronous callbacks. The reason for that is that [[subtle]] is single-threaded and can't use a dedicated thread to wait for the reply, but the APIs of "ALSA":http://www.alsa-project.org/ and "PulseAudio":http://pulseaudio.org are both designed to be asynchronous. Normally event drivven is fine but it is troublesome when you can't use their mainloop.\r\n\r\nSince there is no way to add e.g. a control socket to the event main loop of [[subtle]], the @/dev/mixer@ approach is the only way and works for all sound systems.
