That happens on my nvidia box quite regularly. It also happens without=20
compositing (although apparently slightly less often). Basically I cannot f=
ind=20
a way to work around it, and it's quite annoying (lots of trivial actions s=
uch=20
as switching tabs in konsole make the screen go black and lockup the whole=
=20
machine for 10 or more seconds. It's simply unworkable. Tried upgrading nvi=
dia=20
drivers to latest stable, to no avail.

I'm pretty close to just going over to the hardware dealer to buy a non-nvi=
dia=20
graphics card and be able to use that machine again without banging my head=

against the wall within minutes. We should probably make nvidia people awar=
e=20
of this problem and ask if they can find a solution. Does anyone have=20
contacts?

Specs: NVidia 7600GS, twinview, latest drivers, Ubuntu gutsy and hardy,=20
2.6.24. I've had the problem for some time now, so earlier version of both,=

OS, kernel and nvidia drivers expose this problem.
