I want to thank you then for your help...with my problems...
I'm still figuring out how Linux works... but this helps a lot,
My last question:
When I check everything in the display menu...
I see the right driver nvidia there... and under it... is a box with
accelerated 3d but I can activate it...
Is the nvidia driver already 3d active or this there a command line which must be put in the XF86config file?
