Title:
HDMI reports resolution mismatch on changing users
Status in “nvidia-graphics-drivers” package in Ubuntu:
Expired
Bug description:
I may need some help gathering necessary information for this as I am
not sure what component will be affected, I'm only guessing it is
nvidia as that is the video module loaded.
symptom: on changing users, only sometimes, the HDMI connected screen
goes blank and the monitor hardware reports a resolution mismatch.
Restarting X does not fix the problem, the only solution I've found is
a hardware reboot. The monitor itself only has one resolution so it
cannot be adjusted.
this is a new problem, only since upgrading to 11.10 and persists in
12.04.1
