I have several problems with my Geforce Ti 4200 under Slackware 10.2.
OpenGL based games and also X crash very often, this makes the whole computer going down (is no longer accessable at all).
See this screenshot: (Done with a Digicam after starting up Rune):
I already have tested out different versions of NVidia drivers but i get the same result with all. I also tried this before starting up a Game :
But nothing helps out. Doesn anybody have an idea what i could do, expect testing another Card?
