I am having the same issue with a system with dual vga nvidia optimus

Same issue with a Intel sandy bridge system. But the problem started to show up
around a week ago, probably after some update. before that 12.10 worked fine.

lightdm) will get it running again.
Replaced lightdm with gdm and have now restarted the computer about 10

nothing to do with the proprietary drivers.
