Thanks, Joel. I think that I'm not understanding correctly. You are
suggesting that I disable xgl, however, so far as I understand it is
not enabled now at all. Er, what is aiglx? I just read the wikipedia
article, and it all went over my head. Aiglx replaces the fglrx
driver? Replaces XGL? Another layer in between? Sorry for the
ignorance, us ME majors are not so bright in things CS :)

Thinking more practically, how can I enable XGL on Kubuntu 8.04 to
test if that is better? Thanks.

Q: Why is top-posting such a bad thing?
