Well, I installed Xgl this morning, using the instructions found here (also updated it to have the correct versions of packages it links to) and I have to say it simply rocks my socks.

Might have to add a note to that page about having to manually edit gdm.conf but otherwise, went very smoothly.

One thing that's annoying me is that when I have a conversation window open in Gaim and the person I'm chatting to types something, that window now grabs focus. Quite confusing when I was in the middle of typing an email...
