Unfortunately ati graphics cards have a few setup problems during installation, thankfully it is something that can be fixed fairly easily. The following steps will get basic 1024x768 graphics up and running, the advanced driver installation you would need to follow the linux drivers installation from
www.ati.com.
1) Turn on the computer and on the boot menu highlight SUSE, press F2 to bring up the boot options and type the number 3, then press enter.
2) When the screen comes up login as root.
3) Next type the following without quotation marks "mcedit /etc/X11/xorg.conf"
4) Scroll down the new screen till you see DEVICE and "Radeon". Replace "Radeon" with "vesa", then save and exit.
5) Reboot by typing without quotation marks "reboot", and let it boot normally into SUSE. You should now have a working gui. Go to
www.ati.com to get the latest drivers for your machine and install following ati instructions.
