Public bug reported:

I have an external monitor attached with an HDMI cable to my laptop. I
use Xinerama to use both monitors simultaneously. This works well,
except for when I unplug the HDMI cable. I would expect xorg to reset
itself to single screen mode. It blinks black as if it tries to reset,
but the secondary screen still exists as it's possible to drag the mouse
pointer out of the screen and applications that were on the secondary
screen become invisible and are impossible to move. It would be nice if
xorg could reset itself into single screen mode and automatically move
all applications that resided on the secondary screen to the primary one
when I unplug the cable.

Using Ubuntu 10.10 with fglrx.

xorg:
  Installed: 1:7.5+6ubuntu3
  Candidate: 1:7.5+6ubuntu3

fglrx:
  Installed: 2:8.780-0ubuntu2
  Candidate: 2:8.780-0ubuntu2

What you expected to happen:
That the secondary screen be disabled when unplugging HDMI cable in Xinerama.

What happened instead:
The secondary screen remained active even though I couldn't see it and applications that were on that screen became invisible and impossible to move.
