Yes Travis, I had doubts too about compiz.
In the meantime I found there is a problem in the way drm and radeon modules are loaded I think.
Using Gutsy live cd I found this workaround.
1) Go to ALT+F1 console. 2) stop gdm $ sudo /etc/init.d/gdm stop 3) unload radeon and drm modules $ sudo rmmod radeon drm 4) reload drm and radeon modules in this order $ sudo modprobe drm radeon 5) start gdm again $ sudo /etc/init.d/gdm start
It works for me.
