HowTO: Enable laptop/hardware volume and mute buttons in LXDE

[trulan]

Edit 6-14-2011:  these settings, as well as keybindings in Compiz using the 'commands' plugin, are enabled by default on AVLinux 5.

Here's another neat LXDE-openbox tweak.

If you are using a laptop or a standard multimedia keyboard, you have probably noticed that the volume and mute buttons don't work.  Here's how to fix that:

Code:

gedit ~/.config/openbox/lxde-rc.xml

Hit Ctrl-F (for find) and search for </keyboard>
Right above that line, insert the following lines:

Code:

  <keybind key="XF86AudioMute">
      <action name="Execute">
       <command>amixer sset Master toggle</command>
      </action>
    </keybind>
     <keybind key="XF86AudioRaiseVolume">
      <action name="Execute">
       <command>amixer sset Master 5%+</command>
      </action>
    </keybind>
     <keybind key="XF86AudioLowerVolume">
      <action name="Execute">
       <command>amixer sset Master 5%-</command>
      </action>
    </keybind>

Save the file, log out and back in, and your volume and mute buttons should work.  Cool, huh?

Great tip!!

Thanks for sharing, actually as well 'Clementine' which will be included in AV Linux 4.2 as the music player also lets you map your own multimedia buttons as well, your tip of course is better as a global solution. Thanks again, this is an important missing ingredient.
