| Option "XaaNoOffscreenPixmaps" "true"
| |
| | |
| in the fglrx device section of ''/etc/X11/xorg.conf''.

| | |
| This might also help the pixel errors in the lower right corner that occur on some machines.
| |
| It disables 2D acceleration almost completly and let the CPU do all the rendering. Hopefully the driver will provide better XRender acceleration soon.

| Is required to run compiz.

| ==3D==
| |
| If you plan to run Wine, you will need to tell fglrx to not corrupt the fs register.
| |
| To do this, add the line:
| |
| <pre>
| |
| Option "UseFastTLS" "2"
| |
| </pre>
| |
| to the "Device" section in ''/etc/X11/xorg.conf''. This supposedly causes about a 10% hit in opengl benchmark scores, but at least things don't crash. See also http://wiki.winehq.org/fglrx and http://www2.ati.com/drivers/firegl/readme0325.txt

I found msylef nodding my noggin all the way through.
