Public bug reported:
Binary package hint: gnome-control-center
This may actually be a bug against compiz.
On a Sony VAIO VGN-TX650P laptop with integrated Intel 915 graphics,
Desktop Effects enabled, default behavior with an external VGA monitor
(Dell SP2309W) in karmic is to mirror the displays at the lowest common
resolution.
When I disabled the mirroring and set the external monitor to its full
resolution, the screen goes black (with a small vertical line along the
left edge). The same happens with xrandr --output VGA1 --mode
2048x1152. There is no failsafe to return to the prior working
resolution. Fortunately, I had a terminal open and was able to use
xrandr to return to the prior mode by typing blindly. But I was only
able to do that after several prior times of doing a "hard" poweroff
because the mouse was frozen and the whole system also seemed to be
frozen.
As you can see below, the modes are being correctly picked up, but
something goes wrong when full resolution is being applied and compiz is
running. Full resolution is successfully applied, with no blank screen,
when Desktop Effects are turned off.
