Xgl was a nested Xserver that ran as a GL app in the main xserver.
The main purpose of it was to allow hw accelerated indirect gl on
drivers that did not support it (older version of fglrx).  You don't
need it in this case.  As to why compiz isn't working, you may have to
white list your card (ubuntu), or you may need a newer version of the
r500 3D driver (I'm not sure how often the packages are updated).
What sort of problem are you having?
