ATI Radeon X300

The Dell Dimension 8400 comes with an ATI Radeon X300 graphics card. This is supported as the radeon driver in X.Org, but does not include 3D acceleration. For that you need to obtain the non-free fglrx driver, as described below.

The fglrx driver has a problem with concurrent X sessions, resulting in a total freeze of the machine at times (and regularly) when swapping between X-sessions (as in Ctrl-Alt-F8, etc.). The 3D acceleration (as tested with ppracer) works well though!

Download the driver for X.Org 6.8.0 (also works for 6.8.1 and 6.8.2):

  $ wget

Or else the driver for XFree86 4.3.0:

  $ wget

Download the kernel module (only required for 3D acceleration and you can do without if the binary for your kernel is not available):

  $ wget

Install them:

  $ wajig install fglrx-driver_8.14.13-1_i386.deb
  $ wajig install fglrx-kernel-2.6.11-1-686-smp_8.14.13-1+2.6.11-5_i386.deb

Then modify /etc/X11/XF86Config-4 or /etc/X11/xorg.conf:

Section "Device"
        Identifier      "ATI"
        Driver          "fglrx"
        Option "VideoOverlay" "on"
        Option "OpenGLOverlay" "off"
        Option "UseInternalAGPGART" "no"


Section "Screen"
        SubSection "Display"
                Depth           24
                Modes           "1280x1024"
