opengl and things .. need knowledge sources.
I would like to know more about opengl/3d etc on Linux.
Reason: I have a great Nvidia card (128M) on my gentoo machine, but I cannot get f.e. doom3 to work.
Is there anyone who could give me more on where I can find some good background info on that?
F.e. I read about framebuffers but I still don't have a clue what to do with it.
