OK, thats EXACTLY what we needed to know.

This is quite common with older (and newer) ATI graphics.

Try booting as a regular user, and type "3" in the options line of the grub menu. That will boot you to run level 3 (see page 184/185 of the openSUSE-10.3 reference manual for an explanation of run levels).

By run level 3, I mean that will boot you to an ascii prompt (ie full multi-user mode with network but no graphical desktop).

Lot in as a regular user (use regular user password). Then type "su" to get root permissions (and type root password).

Then type one of the following (I don't know which will work) [note that is zero equals radeonold]

and one of those should configure your graphics for you. Select a conservative graphical setting (if given the choice). You can always optimize this later. Test the graphics if given a chance. Then exit sax2.

Then type "exit" to get rid of root permissions. Type "whoami" to confirm you are no longer root. If still root, type "exit" again.

Once back to a regular user, type "startx". Does that start your X Windows? If so, exit immediately back to an ascii prompt (ie back to run level 3). Then type "su" to get root permissions (enter root password) followed by "shutdown -r now" to reboot.

When rebooting this time, do NOT enter "3" in the grub menu.
