Bug Description
Binary package hint: xorg
In Lucid when running the nouveau driver I can't switch to a console virtual terminal. When I attempt do so, the mouse pointer vanishes and the display freezes on the current X content. Switching back to the X VT returns the mouse and resumes normal operation of X.
I've also occasionally noticed having to switch VTs on resume to "unfreeze" the display after resuming for suspend or failing to see the GDM window on boot (after Plymouth). Possibly related/same issue.

Argh. vga16fb strikes again! The only reason your system is booting at all is because you seem to have 2 monitors plugged in - for some reason vga16fb doesn't kill nouveau in that situation.
Can you try booting with the “blacklist=vga16fb” kernel option - to do that, go to the GRUB menu (you may have to press shift early in the boot process to access this menu), hit ‘e’ to edit the boot options, and add “blacklist=vga16fb” to the end of the kernel line, after “quiet splash”.
That should make everything work properly again. Could you please confirm that?
