I have a Radeon 9700 and trying to execute compiz with the open source driver hangs the X Window completely. I can move the mouse but the screen is totally unresponsive and ctrl-alt-back does not work, I have to reset.
I have tried with the Live CD and the result is the same, once it tries to enable desktop-effects (by default) I get a black screen and the CD stops spinning. The funny thing is that using a Beta Live CD I can log in and desktop effects are working perfectly.
