Comment 25 for bug 475973

Well, next I'd like to forward this issue upstream, but first it must be retested on latest development version of Ubuntu (currently maverick) to make sure the issue still happens there with the latest code. ISO images are available via http://www.ubuntu.com/testing/. If you can reproduce it in the LiveCD environment, you shouldn't need to modify your installed system. Also please attach a fresh Xorg.0.log and dmesg from this testing.
