Compiz works just fine, but I cannot suspend/hibernate if it's enabled. Not having compositing enabled is fine by me.

However, I am unable to log out at all. Any time I try to log out, the screen will turn black and my system freezes.

Any ideas?

ATI is ******* me off. I got this card because it's cheap and works great with Windows but I'd love to be able to use my PC for something other than just playing games (which is what Windows is for).
I got the same problem. I had to use the RadeonHD without Acceleration to get the 4770 stable in 2D. No 3D yet though.
