I have an ATI Technologies Inc RV280 [Radeon 9200 Pro] video card. I was experiencing these issues after upgrading to Karmic 9.10.
* black background under Compiz
* windows larger than 1024px were black
* full-screen videos in VLC or Totem were black
* very choppy (~2 frames per second) full-screen compiz effects (like the desktop cube switcher effect, or the scale effect)
The steps in comment #3, to create /etc/modprobe.d/radeon-kms.conf, fixed the problem for me and returned my system to Jaunty performance levels.
