You have been subscribed to a public bug:
I updated 12.04 today, and it included some kernel updates and other
stuff. Dual monitors become compressed/recentered onto one monitor on
reboot. The only workaround seems to be to boot with only one monitor
connected and then plug in the second after Ubuntu has completed reboot.
Graphics card is an NVidia with dual DVI ports, processors is intel i7
Release is Ubuntu 12.04.2 LTS release 12.04
What I expect to happen: Start normal
What happens instead: One monitor of dual monitor receives no signal,
the other appears to shift its normal display left half a screen,
leaving the right half filled with the purple Dalek polka dot Ubuntu
pattern.
