Comment 22 for bug 458545

This also affects the graphs on the overview window of Hamster-applet - see bug #451916

I tried some testing with the xorg-edgers packages to isolate this. The fix is in the xserver-xorg-video-intel package, upgrading it alone and leaving the rest of the Xorg stack with the default Karmic version fixes the problem.

The fix is present in the oldest version still available in the PPA (2:2.9.0+git20091026.10946118-0ubuntu0tormod), and if someone can tell me where to get older packages, I can find an exact version if that would be helpful. I do know that it was likely fixed in the PPA sometime in October. Grepping through the apt logs from my old jaunty install shows that 2:2.9.0~git20091010.8b2d2ff0 was installed at some point, but I can't 100% confirm it was broken on that version.

Hopefully someone on the Ubuntu-X team can find and backport a fix to this issue.

Those looking for an immediate solution can install an xserver-xorg-video-intel .deb from https://launchpad.net/~xorg-edgers/+archive/ppa/+packages?field.name_filter=video-intel&field.status_filter=published&field.series_filter=karmic

Let me know if there is any additional information I can provide.
