Cause I'm using virtualbox I've installed the package linux-headers-3.5.0-17-generic. My system with nvidia GTX260 (packages nvidia-current + nvidia-settings from ppa:xorg-edgers) and dual monitor mode worked fine.
But yesterday I did a system software update. The update installed kernel 3.7 and broke the system.
Only one monitor (with bad resolution 1024x768) was active. There was only my custom wallpaper and mouse visible (no appmenu, no menu).
