Hi John,

That sounds interresting. We are using an Open GL Driver from Nvidia (verison 5336-1),
but the program hangs even when launched remotely (but for sure it still uses the
Nvidia library calls...).

The problem is I want to run a CAVE + GL version of vmd, and CAVE requires OPENGL
and not MESA.
