Well, Just googling for AMD linux NVIDIA GeForce 2 MX should give you a
hint.
The problem is a CPU bug (or a linux kernel bug depending on who you
ask) that causes OpenGL problems when using AGP with 4MB Page Table
lookups on certain AMD chips. The Athlon XP family is one of these
chips.
You have three options.
1. at lilo, type:
linux mem=nopentium
this should disable 4MB Page Table lookups and use 4KB pages instead.
The problem is that this requires 1023 extra lookups per lookup.
2. in XF86Config, under the Driver section, add:
Options 'NvAGP' '0'
I think that's what it is... can't remember correctly, but look at your
NVIDIA documentation. Basically, turn of AGP
3. Upgrade to linux 2.4.19 at least.
Also make sure you're using the GLX drivers from the NVIDIA site and not
the drivers that come with X. You may also need the kernel drivers if
your kernel is older than 2.4.20.
