Comment 58 for bug 47775

I have the same problem with a IBM Thinkpad T41 and the ati/radeon driver.
At the office I use an external CRT monitor (hp p1130).

The laptop freeze a few times a week. The machine is stone dead and have to be rebooted. it does not respond the ping either...

Ubuntu Breezy did not have this problem at all.
