<pre>Hi, I'm seeing this same behaviour on my system:
so thank you for the restart-Xorg tip!
Here Debian testing on nvidia optimus laptop (see [1] Debian bug I've filed).
Relevant entries in Xorg.0.log:
[ 21.061] removing GPU device
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1 /dev/dri/card1
[ 21.061] xf86: remove device 0
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1
[ 21.061] (II) NOUVEAU(G0): NVLeaveVT is called.
[ 21.062] (II) NOUVEAU(G0): Closed GPU channel 0
[ 21.062] (II) UnloadModule: "nouveau"
IMHO, bug is probably located outside ati driver, because of bug showing itself
both with nvidia and ati double card systems, so you should change the
"Driver/Radeon" component specification.
Just a clue, don't know if it's right!
Hope to help getting this fixed soon, for both ati and nvidia
Cheers,
Marco
