Comment 33 for bug 350306

I can confirm the problem on

Ubuntu 9.04
Kernel: 2.6.28-15-generic #48-Ubuntu
Graphics: intel 82945G/GZ integrated graphics controller
xserver-xorg-video-intel 2:2.6.3-0ubuntu9.3

It occurs randomly, but very often I'm logged of when I switch my KVM-Switch back to the jaunty-machine.
