LXDE-VolumeControlOSD

Adds laptop media keys (volume +/-/mute) support and OSD for LXDE with pulseaudio and xfce4-notifyd (lubuntu 14.04 base setup). Tested on a ThinkPad X240.

##Installation

1. Install notify-send (libnotify-bin package in ubuntu/debian).

2. Move the volumeControl.py script to the user's ~/.config/openbox/ directory and modify the *rc.xml file within. Add to or update its <keyboard> section accordingly:

   <keyboard>
    ...
    <!-- Keybinding for Volume management -->
       <keybind key="XF86AudioRaiseVolume">
         <action name="Execute">
           <command>python3 ~/.config/openbox/volumeControl.py raise</command>
         </action>
       </keybind>
       <keybind key="XF86AudioLowerVolume">
         <action name="Execute">
           <command>python3 ~/.config/openbox/volumeControl.py lower</command>
         </action>
       </keybind>
       <keybind key="XF86AudioMute">
         <action name="Execute">
           <command>python3 ~/.config/openbox/volumeControl.py toggle-mute</command>
         </action>
       </keybind>
   ...
   </keyboard>

3. Then reload openbox by delogging/relogging or invoking openbox --reconfigure in a Terminal window.

##Notifications display You might want to force the notifications to stack by adding the following snippet to the <applications> section of *rc.xml:

<!-- Force notifications position -->
<application class="*notifyd">
    <position force="yes">
        <x>center</x>
        <y>-50</y>
    </position>
</application>

###Customization To customize the position of the OSD, change x and y values. Top (y) and left (x) borders of the screen are (+)0, right (x) and bottom (y) -0. E.g. A y value of -50 will make windows appear 50px away from the bottom of the screen.

##lubuntu/xfce4-power-manager OSD workaround: xfce4-power-manager handles brightness +/- keys and its OSD which position cannot be forced by openbox *rc.xml configuration. If you want to disable this OSD (courtesy of docs.xfce.org): xfconf-query -c xfce4-power-manager -n -p "/xfce4-power-manager/show-brightness-popup" -t bool -s false
