Thanks for all help !
I don't know why nVidia and Open SuSE
community provides WRONG link to the latest drivers???
I spent few days to test everything possible with driver version 169.12 (from February 2008)
Link from OpenSUSE.org
goes to the driver:
Latest Version: 169.12
Latest Legacy GPU version (1.0-71xx series): 71.86.04
Latest Legacy GPU version (1.0-96xx series): 96.43.05
BUT (!) if you go to "Archive" you can find this:
Linux Display Driver - x86
Operating System: Linux x86
Release Date: March 07, 2008
I found this only because I thought I will try with older drivers.
Even If I search for driver for my card (GeForce 8500 GT) it points to the driver 169.12 (from February).
All my problems went away after I installed latest driver: 171.06 and executed:
sax2 -r -m 0=nvidia
Strange but I see correlation with another problem I had. I could shut down my OpenSUSE. It usually stopped at:
Master Resource Control: runlevel 0 has been reached
Skipped services in runevel 0: SUSEFirewall2.setup
After I installed nVidia driver and it works, I can shut down my system without any problems.
