Hoi,
The same
problem occurred on my Dell Dimension 3000, and
others reported
similar issues.
Apparently, there is still a bug in the new 6.8.2 version xorg-x11 that works with the i810 drivers. Sofar I've not been able to find a solution, but maybe
this will work. I've not tried it myself as I'm not near my PC now.
Let me know if it works.
