Where are acpi event scripts that are binded to keyboard shortcuts?

[Andre Rodovalho]

For display config. I simply add

*<keybind key="XF86Display">*
*      <action name="Execute">*
*        <command>lxrandr</command>*
*      </action>*
*    </keybind>*

to lubuntu-rc.xml file. To mute I do:

* <keybind key="XF86AudioMute">*
*      <action name="Execute">*
*        <command>amixer -q sset Master toggle</command>*
*      </action>*
*     <action name="Execute">*
* <command>amixer -q sset Speaker unmute</command>*
*     </action>*
*    <action name="Execute">*
* <command>amixer  -q sset Headphone unmute</command>*
*      </action>*
*    </keybind>*

This might open your possibilities while trying to make several commands on
a single button activity.
