Update the package pam_devperm with YOU (YaST Online Update)
Add all local users to the group video in order to provide them with write permissions for the Nvidia devices (/dev/nvidia*).
Use the nv module as controller for Nvidia graphics cards. The easiest way of doing this consists of editing the file /etc/X11/Xf86Config with an editor of your choice (pico, vi, emacs, etc.).
Search for the following section: Section "Device" BoardName "GeForce 2 MX" BusID "1:0:0" Driver "nvidia" Identifier "Device[0]" VendorName "Nvidia" Option "NvAgp" "1" EndSection and change it to: Section "Device" BoardName "GeForce 2 MX" BusID "1:0:0" # Driver "nvidia" Driver "nv" Identifier "Device[0]" VendorName "Nvidia" Option "NvAgp" "1" EndSection
The next time the X server is started, the nv module (instead of the nvidia module) will be launched. An undesirable side-effect: the 3D acceleration will be disabled!
