I am using ubuntu 13.04 and just loving it.
I have assigned keyboard shortcut to quick shutdown. I found this method through google.
I created a custom shortcut through command
dbus-send --system --print-reply --system --dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop
I have been trying to do the same to quick reboot but I can't find it anywhere on Google.
Please help, thanks in advance, I haven't got much knowledge of command line.
