How do I configure X to use ATI 3D accelerated graphics

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

ATI Radeon cards 8500,9000,9200 and 9250 work with Open Source drivers and support ["OpenGL"] 3D Graphics.

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"

 Section "Screen"
        Device          "ATI 3D"

Install the required libraries

It is necessary to install driver libraries, in order for the 3D capabilities of the card to be utilized:

 apt-get install libgl1-mesa-dri


glxinfo|grep render
