Too bad 3dfx went belly up. I've never used glide but from what I hear you can do really nifty
stuff with it =).

A GeForce 2 GTS, but I switched to Gentoo GNU/Linux so at the moment I only have FreeBSD on my
server. Although I compile ada stuff on it some times and forward the output to my desktop =).

Why do you want both Mesa and nVidia? Look for files called /usr/X11R6/lib/XXX-*, this is what
nVidia renames the existing libGL libraries to. If you have an XXX-libGL.a.%%.orig-<date> rename
it to libGL.a and it should work.
I don't think you should have both Mesa and nVidia though. That is asking for trouble.
