These notes are for an ["Xorg"] based ["xserver"]. To install the ATI Radeon drivers on an ["XFree86"] installation, see ["ATIHowToXFree86"].

To configure X to use accelerated 3d drivers, the configuration file /etc/X11/xorg.conf should be edited as follows:

  • Section "Device"
    • Identifier "ATI 3D" Driver "ati"

    ?EndSection Section "Screen"

    • Device "ATI 3D"

  • apt-get install libgl1-mesa-dri
