Why doesn't Compiz work on an Ati card?

As far as I know, this card has 3D-acceleration with the free radeon
driver. Check /var/log/Xorg.0.log to see if you indeed use it, and
everything is set up ok.

You did not explain how exactly compiz does not work? What happens?

I have Xgl+Beryl running on an ATi X1300 with the proprietary drivers.
But a manual setup was required, and I still have some issues, as I
always had with ATi drivers -- they suck. Nvidia is slightly better, but
if you do not need the PC for gaming, go with the Intel cards, for which
free drivers exist.
