From Compiz

Some options for the free drivers listed on the page are not quite correct:

1.) When using "AccelMethod" "EXA" then "XAANoOffscreenPixmaps" makes no sense since this requires "AccelMethod" "XAA".

2.) Furthermore it should be noted, that the "AccelMethod" "EXA" might crash the graphics driver in some configurations when compiz is starting (R300 driver on a X300 chip, Xorg 7.2 on Ubuntu Feisty). So using "AccelMethod" "XAA" should be mentioned as an option when crashes are experienced.

Missing information: 1.) fglrx 8.42 shall support AIGLX 2.) What about the new drivers radeonhd, avivo?
