Hi all. I'm a Linux newbie (winxp convert) and need some help setting up my video card drivers on Ubuntu Linux.

First of all, here is my core system setup:
Motherboard: MSI K7N2 Delta
Video Card: ATI Radeon X800 Pro (256 MB RAM).
Monitor: Sony HMD-A440 19"
Processor: AMD Athlon 2500+
RAM: 1GB dual-mode DDR

I used the Synaptic Package Manager to download and install fglrx and fglrx-control. fglrx is the free ATI driver, and fglrx-control is the control panel for it (which I have still been unable to find).

After I installed it, I rebooted and ran fglrxconfig, the configuration utility which rewrites XF86Config-4, the X-Server configuration file. This is the XF86Config-4 file it generated.

# XF86Config-4 (XFree86 X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the XF86Config-4 manual page.
# (Type "man XF86Config-4" at the shell prompt.)
#
# This file is automatically updated on xserver-xfree86 package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xfree86
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands as root:
#
# cp /etc/X11/XF86Config-4 /etc/X11/XF86Config-4.custom
# md5sum /etc/X11/XF86Config-4 >/var/lib/xfree86/XF86Config-4.md5sum
# dpkg-reconfigure xserver-xfree86

I did notice in the log after running fglrxconfig a message stating that no supported video card was found, although I am running an X800. However, in the list provided at the start of fglrxconfig, the X800 is not listed. I am probably foolishly assuming that my card is supported when it's not.

So I restarted xserver using the command: sudo /etc/init.d/gdm restart

Everything came up fine, but I wanted to change my screen resolution and this is the error message I got:
--> The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available.

Anyone see anything, maybe in the XF86Config-4 file, that jumps out at you?

I haven't even TRIED playing a game with this yet I also tried the official ATI drivers but I'm still a linux noob, so converting the package to .deb and all that didn't seem to work for me at all... long story short I couldn't get it installed and the package manager was much easier.

There is a relatively obscure fix for this on the Ubuntu Forums.

In your Xorg.conf, make sure this is included in the Modules section rather than "Load extmod"
------------------------------
# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
SubSection "extmod"
Option "omit xfree86-dga" # don't initialise the DGA extension
EndSubSection
