I've played around with all of the above for a couple of days now. I
also re-installed everything on this laptop twice (because I was also
working on other things). Despite all of the tweaking, there was very
little change overall in performance.
fglrx = slow
radeonhd = faster, but somewhat problematic (3D stuff/compiz don't work
well)
radeon = a little slower than radeonhd and limited in capability (2D
only)
At least that's the case for me. I'll keep trying, but for now I've
renamed my xorg.conf to a backup file and switched back to Intel
graphics. While less than ideal, at least Compiz loads and more of the
3D stuff runs...
Cheers,
Chris
