I have:
HP 8530p
ATI Radeon 3650
Gnome
Suse 11.1 64 bit
Desktop effects enabled
Cairo-dock
OpenOffice 3

After a couple of cut and paste operations from Mozilla to OpenOffice, my screen locks up and I have to hard boot. It's similar to the problem I had with the ATI driver without the ACPI-Services=off switch.

Anyone else having this problem?
