Ctrl-Alt-Del should open the gnome-system-monitor at the processes tab. This fix uses the commands plugin to override the default action. This includes: - Install the commands plugin by default. - Breaks/Replaces the compiz-plugins package for versions earlier than 0.9.10. - Patch commands.xml and integrated.xml to map gnome-system-monitor to Ctrl-Alt-Del by default. - Start the command plugin upon Compiz starting.
