Card: Code: 01:00.0 VGA compatible controller: nVidia Corporation G80 [GeForce 8800 GTS] (rev a2) Driver: Code: NVRM version: NVIDIA UNIX x86_64 Kernel Module 260.19.06 Mon Sep 13 04:29:19 PDT 2010 GCC version: gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5) How can I tell about the 32-bit libGL? Does this tell you anything?

I'm running Ubuntu's version of the nVidia X server. Should I get a newer driver from nVidia? Thanks. Damian
