Hello!
Thanks for your reply!

My out put from glxgears was:
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

Seems like a problem to me, but perhaps you can tell me what?

My hardware is:
Motehrboard ASUS P3B-F
Graficcard Nvidia Riva TNT
Screen Multisync LCD 1500M

I guess that is all that may be interesting?

So if any one got an idea whats wrong please tell me!

Best regards
Fredrik
