My guess is that your graphics were not configured properly for some reason.
Can you tell us what graphic hardware your Dell Studio XPS 13 has ?
You could load a generic vesa driver as an interim, or you could use the installation xorg.conf file as an interim.
I recommend you reboot the PC. When the grub boot menu comes up (that is where you can choose, openSUSE-11.1, or safe settings, or windows, … ) choose openSUSE-11.1 (probably the default) and type “3” (no quotes). The “3” should appear in the options line in that menu. That will boot to run level 3 (which is an ASCII text screen).
Log in there as a regular user. Enter regular user password.
Once logged in, type “su” (no quotes - enter root password when prompted) to get root permissions.
You can determine your graphics by typing:
which will say what graphics you have. What does that say?
Then 1st try the installation xorg.conf file (where xorg.conf is the configuration file for your graphics). Do that by typing:
cp /etc/X11/Xorg.conf.install /etc/X11/xorg.confNote the directory is X-one-one, not X-L-L.
Then reboot by typing:
shutdown -r now
and see if that works? [this time do NOT type “3” ]
If that does not work, then reboot again, type “3” in the grub boot menu, and login as a regular user at the ASCII prompt. Again, after having logged in, type “su” (no quotes - enter root password) to get root permissions. And then try to load the vesa driver by typing:
sax2 -r -m 0=vesaNote that is “zero equals vesa”.
choose a very conservative resolution for now.
Exit sax2. Again type:
shutdown -r now
to reboot. Do not type “3” in grub menu, and see if that works.
