Joresarcos, after all the “dust settles” (or zigzags disappear) you could consider writing a bug report on one of the openSUSE graphic drivers. My guess is your PC is using the openGL “nv” driver, although it is possible it is using the “vesa” driver. Still, this should have worked automatically. Guidance for writing a bug report is here: Submitting Bug Reports - openSUSE
There was a change made between openSUSE-11.1 and 11.2, where in openSUSE-11.2 an effort was made to make automatic graphic configuration more automatic. … Unfortunately, that has not worked for everyone. …
The openSUSE-11.2 release notes had this to say:
openSUSE 11.2 Release Notes
YaST and X.Org Configuration (Keyboard, Mouse, Graphics Board, and Monitor)
In the past, YaST offered an configuration interface for the graphical desktop (X.org) such as keyboard, mouse, graphics board, and monitor. During the installation a suitable xorg.conf was created.
In most cases it is no longer needed because the Xserver is now able to automatically configure the system. If it fails for your system, try the following steps:
Check whether an old /etc/X11/xorg.conf file exists. If so, move it away and start your desktop again.
If it still does not work, run sax2 from the command line and execute the configuration procedure.
To adjust hardware components to your personal needs, start the GNOME desktop control center or Configure Desktop in KDE, and configure your devices such as the mouse or keyboard. The display configuration dialogs also let you configure multiple monitor setups. To configure multiple monitors, in other desktop environments, use xrandr.
For more information, see the Desktop User Guides shipping with openSUSE. They are also available from Documentation - openSUSE
Now there are typically 3 graphic drivers that are used with a nVidia card (although there is a 4th in the works), with these 3 being:
- a generic video driver that works with almost all nVidia, ATI, Intel, etc … graphic hardware. Performance is poor, but compatibility is high. It is fairly robust in that it will work with various kernels and xorg apps without a need to rebuild the driver
- an opensource free (free as in free software foundation defintion of free - openGL) graphic driver specific for nVidia cards. Theoretically should work with all cards. It has better performance than the vesa driver, although its performance likely is not good enough for 3D/special desktop effects. It is fairly robust in that it will work with various kernels and xorg apps without a need to rebuild the driver
- the proprietary (free as n free beer) graphic driver. Best performance. Special desktop effects work with most average to new hardware. But very sensitive to kernel updates and xorg updates which can break the driver, forcing a rebuild of the driver
Typically, with 11.2, the “nv” driver is setup by default.
Check if you have an /etc/X11/xorg.conf file. You probably do not. If you do, then move it somewhere (or rename it) per the release note recommendation and reboot. Does that help ?
If not, then try to force a custom graphic configuration by running a tool to create a configuration file for your graphics … that file being /etc/X11/xorg.conf file. You can do this by booting your PC to “run level 3” text mode, so you can change the driver. You can boot to “run level 3” by rebooting your PC and when the initial boot menu appears (where you select windows or openSUSE or openSUSE fail safe) press “3” (no quotes) so that “3” appears in the option line (with a space between it and the preceeding entry). Then select the openSUSE boot and boot the PC. It will boot to a text login. Login as a regular user. Once logged in, type “su” to switch users to root (administrator). Then send one of the following two commands to configure your graphics (assuming you have only one graphic device):
sax2 -r -m 0=vesa
#that is zero equals vesa and it sets up a configuration for loading of the slower vesa driver
sax2 -r -m 0=nv
#that is zero equals nv and it sets up a configuration for loading of the moderate speed nv driver that should now be set up ok, but did not succeed. Note you do not have to accept the sax2 suggestion, but you can say no to its resolution suggestion and it will give you an option to tune the resolution. You may wish to try something conservative intially.
Once you have exited sax2, then type “shutdown -r now” to reboot, and do not press “3” this time when rebooting.
Once you get a stable graphics, you can look at loading the proprietary graphic driver by following guidance here:
