[915G] Xorg crashed with SIGABRT in raise()

[Moba Rob Ber]

I don't know what happened here. Ever since I put the 12.04 the whole Ubuntu experience has been turned upside down on its head. Everything seems to be buggy and crashing. I wanted to disable the guest login, so I edited lightdm and added "allow-guest=false" Now te unity launchpad is missing and hings are not working.
