Thanks for your report.

Moving to xserver-xorg-video-nouveau since it's the video driver in use. I noticed that you're using kernel version 3.0.0-0300rc1-generic

Are you able to reproduce the problem with 2.6.39.3.4 ?

Hello
Another strange thing.
After installing 2.6.39.4/Oneiric-all.deb, & -headers & -image if I boot the system in the default 3.0 kernel I cannot reproduce this bug

From the comments, it sounds like this is a regression in the kernel between versions 2.6.39.4 to 3.0.0-0300rc1. A git bisection search can be utilized to narrow in on where the regression occurred. Please see https://wiki.ubuntu.com/Kernel/KernelBisection

Reassigning to the kernel team for further follow up, since they'll need to ensure the faulty patch is backed out or replaced.

The kernels being used/tested here appear to be the mainline kernel builds. The mainline kernels builds are produced for debugging purposes and therefore come with no support. Use them at your own risk. It additionally appears you are using the v3.0-rc1 kernel (ie an early v3.0 release candidate)

So, please test with the most recent 3.0.0-8.10 Ubuntu kernel. It was most recently rebased onto upstream stable v3.0.1.
