ATI Radeon x1950 Pro, Dual Monitors working, but no Compiz

I have spent several hours scouring the web for solutions to this problem, but from all I can see, what I have should be working.

I currently have two monitors working with my card, using kwin as my window manager. When I try to enable compiz, it reports that the Compositing extension is not enabled:

fglrx is working, as indicated by fglrxinfo:


display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon X1950 Series
OpenGL version string: 2.1.8494 Release

Finally, it appears to me that compositing is enabled, as


#grep Composite /var/log/Xorg.0.log
(**) Extension "Composite" is enabled

I hope that someone can give me a clue as to where to go next. I have tried just about everything I know.
