Hello.
I have installed openSUSE many times on this computer (same hardware and everything). I currently own an 8800 GT 512 MB, and have installed the drivers fine several times before. I installed the one click nvidia drivers on this install and rebooted. X couldn’t start, so I had to switch to the nv driver in my xorg.conf. I have also tried the hard way method described in the wiki, but to no avail. So, The tools for nvidia are all installed, all of the dependencies are installed, but I still can’t use the nvidia driver. I have been stuck on this problem for about 2 weeks, and I need to get it working soon for my oGL development.
If you need any more info just say so… this post might be a little vague.
Did you try switching to single user mode (init 3 as root) and then trying to configure sas manually: Login as root type sax2. Configure the card and then exit. Then type init 5 to startx.
