I agree with Geir's assessment that Chris' bug is the one we should take
upstream, so I'm reversing the dupe on this, even though this one was
reported first. Hopefully whatever solves Chris' problem will do
Just running xrandr doesn't do anything. the output is:
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
VGA1 disconnected (normal left inverted right x axis y axis)
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 287mm x
215mm
1024x768
I've noticed that the graphics adapter resets itself to 85Hz refresh
rate - which causes the screen corruption - rather spuriously: when
connecting external monitors or coming back from sleep.
When the screen comes back from sleep, and the refresh rate is reset to
85Hz, I get this in Xorg.0.log:
Great that you found out that it was the 85 Hz frequency that causes the
corruption. I have never seen a LVDS display running at 85 Hz before.
The added lines to Xorg.0.log is from EDID probing. This also happens
when you run xrandr. Does simply running xrandr cause problems as well?

Re: comment #3 - yes, I have compiz enabled.

I was asking if you could try it with compiz disabled to see if it
happens in that case as well, I have a feeling I know what it is and it
would only happen when compiz is enabled.

Oded, could you attach /var/log/Xorg.0.log, /etc/X11/xorg.conf, and the
output of `lspci -vvnn` here? You can attach this and some other useful
information semi-automatically by running `apport-collect 396171`.
