I had this problem with Kubuntu which took me some time to figure out. It turned out to be something really dumb.
"Xlib: extension "XFree86-DRI" missing on display ":0.0"." You see.. Ubuntu and Kubuntu use a Restricted-Driver manager to load/unload non-FOSS drivers. Even if they are installed and specified in the xorg.conf does not mean they'll load properly. If you use GNome as your Windows Manager then you can load the Restricted Driver's Manager from the System or Preference's menu (I can't remember which). Ironically.. If you use Kubuntu then this particular menu item is missing. In order to load the Restricted Driver Manager in Kubuntu then.. sudo /usr/bin/restricted-manager If you check the box and reboot then it should change this message: "Xlib: extension "XFree86-DRI" missing on display ":0.0"." To this one: OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: RADEON X600 PRO OpenGL version string: 2.0.6334 (8.34.8) If you are running glxgears and getting 400-600 frames per second using either Ubuntu or Kubuntu or your video playback seems a bit slow then this may also solve your problem. This also corrected my problem getting mplayer to play multiple videos in multiple windows on multiple monitors simultaneously without a loss in quality.
