Screen resolution wrong after latest 12.04 update

[Bruce Kaufman]

I just installed an update for 12.04, which required a reboot. After the reboot, the screen resolution is wrong (screen is stretched). The Monitor utility says my screen is LAPTOP (it's not) and the "detect Monitor" button does not do anything.

Also tried changing resolution using grub-customizer but it doesn't seem to help either. In fact now on boot I get "error: no video mode activated"

Also unplugged monitor.

Suggestions?

Thanks,

[ManamiVixen]

Care to describe what hardware you have? Memory, CPU, Graphics, ect....
