Bug Description

Binary package hint: xserver-xorg-video-intel

Steps to reproduce:
- activate desktop effects (i.e., enable compiz)
- attach external monitor (laptop has VGA only)
- run xrandr without parameters (either in commandline or via System->Settings->Display Resolution

Symptoms:
- external screen gets a signal and wakes up from sleep
- internal screen turns black (but does not deactivate)
- external screen remains black
- moving the mouse shows the normal gnome cursor
- moving the cursor out of the internal LVDS screen makes it appear on the external screen

The last point of the symptoms section ("moving the cursor out of the internal LVDS screen makes it appear on the external screen") surprises me a bit:

in earlier releases of ubuntu, the maximum desktop size is limited, read I was not able to combine the internal LVDS (1024x768) with my external display that has a much larger resolution of 1920x1200. This new behavior however shows that the mouse coursor can reach both screens independently.

The other interesting observation is that a simple query auto enables the external screen in a "extended desktop" configuration. Is this behavior intended or a (possibly related) defect?

I have the same result as a problem, but with a Thinkpad T60 and kernel 2.6.31-16-generic .
it is also a intel 945.

hm, I see that mine is actually a problem with OpenGL / Compiz. When I start metacity and then attempt the changes it work again...

The hint with compiz is excellent, using plain metacity does not crash the GPU.

Further references that might be related to this issue:

http://bugs.archlinux.org/task/17725
http://forum.ubuntuusers.de/topic/dualview-haengt-sich-auf/#post-2273500
Bug #329860 (but this is with vt switch, not with external monitors. Might be a seperate problem but symptoms look similar)

possibly https://bugs.freedesktop.org/show_bug.cgi?id=22996

based on these references, and the fact that Felix experiences similar behavior, I'm triaging this this bug accordingly.

I still experience this behaviour with the latest updates (2010-01-15 17:00 UTC+1)
libmesa-dri 7.7-0ubuntu5
xserver-xorg-video-intel 2.9.1-1ubuntu1
I do not have compiz enabled - just plain metacity. A week ago everything was fine with my system ...

are you sure that the kernel messages in your /var/log/kern.log are the
same as here?

if not, you may be experiencing another bug which should be filed
seperately.
