I'll give it a go and report back. Holy Crap! EXA makes a ton of difference! I can resize windows now without having to drag, un-click and ... wait. Man that's good. Now if I could only get the openGL screensavers to work. All-in-all, I'm amazed at how good EXA works. Not near as fast as fglrx, but not too far behind. Thanks Wil! -- David C. Rankin, J.D.,P.E.

XAA & EXA are the 2 different acceleration methods for most X drivers. Intel additionally has UXA, but its based on EXA.I don't know about the radeonhd driver, but the ati one defaults to XAA even tho EXA generally provdes better performance these days (the commit has been made to change the default to EXA in git, its just not released yet). Just add a line like Option "AccelMethod" "XAA" or Option "AccelMethod" "EXA" to the Device section in your xorg.conf file to change between them. /var/log/Xorg.0.log will confirm what is getting used.
