Comment 26 for bug 462939

With the latest updates and kernel: 2.6.32-22-generic the problem seems to be fixed, although it persist with 2.6.34rc3-51-generic

I am quite unsure regarding what the solution may be, because I have been messing quite a bit around with my settings (xorg.conf) now using intel driver, UXA grafics accelleration according to http://www.ubuntugeek.com/intel-graphics-performance-guide-for-ubuntu-904-jaunty-users.html

Right now I am not going to change a working system. :-)
