This is happening to me running 12.10, kernel 3.5.0-26. I was using the Nvidia driver and thought switching to Nouveau might help but it was the same. So this does not seem to be an Nvidia related issue. At least in my case I am thinking this could be a software reaction to faulty hardware: I am running on an XPS m1530 and for a while even the BIOS POST was not visible. The screen was lit, but remained black. It seems to be starting again, but now I get fatal IO errors showing up in /var/log/syslog and get booted out to GDM. Just before this happens the screen either freezes, goes all blocky or gets crazy rainbow colored banding.
