[edit] Screen Rotation
On Catalyst 8.9 and later ATI drivers now support RandR rotation. After configuring your ati card as usual enter the following string. aticonfig --set-pcs-str="DDX,EnableRandr12,TRUE"
Then restart X11. Your xrandr should work.
Note: Using this command on a Radeon Xpress 200M made Xorg unable to start with some weird error in the amdxmm module. Using this command with FALSE instead of TRUE helped afterward. Note: I also had a problem with that option with a 4850, I couldn't get Xorg to start after setting that option.
Q: Is rotation hardware accelerated? How does performance compare to non-rotated?
[edit] Open Source Drivers
ATI Radeon cards 8500,9000,9200 and 9250 working with open source drivers provide OpenGL 3D graphics acceleration.
[edit] Proprietary Drivers
Proprietary drivers can be used instead, if so desired, although it is not necessary to use these for the cards listed above.

[edit] X server
- XFree86 and X.org support
[edit] Xaa
- X Acceleration Architecture
[edit] Xv
- One Hardware or OpenGL overlay

[edit] OpenGL
- Provides some OpenGL 2.0 commands
BUT NOT the OpenGL 2.0 version of the shading language.
The ATI driver uses a version of the shading language called the ARB extension. The ARB extension was used before OpenGL 2.0 was finished.
