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 http://www.stanchina.net/~flavio/debian-fglrx-xorg/fglrx-driver_8.14.13-1_i386.deb
Or else the driver for XFree86 4.3.0:
$ wget http://www.stanchina.net/~flavio/debian-fglrx-xfree86/fglrx-driver_8.14.13-1_i386.deb
Download the kernel module (only required for 3D acceleration and you
can do without if the binary for your kernel is not available):
$ wget http://www.stanchina.net/~flavio/debian-fglrx-modules/fglrx-kernel-2.6.11-1-686-smp_8.14.13-1+2.6.11-5_i386.deb
$ 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
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
Option "UseInternalAGPGART" "no"
