Recently my SuSe 11.1 install stopped booting, after further investigation I found the following error in the log files: Fatal Server Error: No Screens Found after some hunting around the net, and many failed tests. I finally managed to resolve the issue..
If you are suffering from the same problem, try:
Log in as rootType “sax2 -m 0=vesa”
This should load the vesa driver.
Now reboot and you should find you will at least get your GUI back.Once logged back on, you may then want to adjust your display driver etc.
