Is this a dual-head system, too, or do you have just one display?

For what it is worth, I have not experienced the problem since my earlier
report that Linux 3.1 seems to fix it.

So the bug appears to be better hidden now, which tends to make fixing harder.

Maybe some driver developer can suggest a way out?
