Radeon Graphics cards and Suse Linux

I discovered that Radeon Graphics cards are not support in natively in Suse Linux therefore I had to go to the ATI Technologies site and download the Linux drivers. Firstly I found out what version of Xorg I was using by typing "Xorg -version" and then download both the installer and the appropriate driver. The site has instructions on how to install the driver and I just followed those.

Once I installed the driver I had to play around to ensure I had the right screen resolution and refresh rate. I tried using sax2 but this didn't help so then I edited the xorg.config file in /etc/X11/.

First I backed up the file and then found the section:
Section "Modes"
Identifier "Modes"
Modeline "1024x768" 92.05 1024 1088 1200 1376 768 769 772 806
Modeline "800x600" 55.22 800 840 928 1056 600 601 604 630
EndSection

I hashed out the modes I didn't want and typed xmode xmode -x1152 -y864 -r60 into a terminal and copied and pasted this line in the file.

Resulting in something like this:
Section "Modes"
Identifier "Modes[0]"
#Modeline "1024x768" 92.05 1024 1088 1200 1376 768 769 772 806
#Modeline "800x600" 55.22 800 840 928 1056 600 601 604 630
Modeline "1152x864" 78.22 1152 864 928 1056 600 601 604 630
EndSection

I then restarted X using "ctrl","alt" and "backspace" which caused my system to crash. Therefore I had to type "startx" to get back into kde.
