[Bug 583165] [NEW] Ubuntu thinks two monitors are connected.

 

Public bug reported:

Binary package hint: xorg

Dell Latitude E5500. Intel video. Ubuntu 10.04. At one point I connected
a Dell 17" monitor and ran dual screen, by going to System - Preferences
- Monitors. Well, the monitor is out of the picture now, and has been
for the last week. However there's times I boot up and my login screen
is missing. By curiosity, I moved my mouse to the right, and sure enough
it disappeared instead of "hitting a wall", proving Ubuntu thinks
there's a second monitor existent when there is not. This problem also
messes around with my resolution as well, forcing me to change it back
each time this happens. Out of about 10 power-ups, this happens anywhere
from 2-4 times.
