[ubuntu] Power Button not working at login screen

http://ubuntuforums.org – Hi there, being quite new to Ubuntu I encountered the following issue: On Ubuntu 12.04.1 pressing the physical power button on the machine shuts down the pc. However, this only works if a user is logged in, i.e. there's no effect of power button presses at the login screen. Is this the intended behavior? If yes, any way to make it shutdown at the login screen after power button press also? Any hints are greatly appreciated. Thanks. (Hardware)
