Hi,

I am running Ubuntu 12.04 LTS. I was using VMD 1.9.1 (the precompiled
binary) without any problem. But recently I encountered some slow response
time while running VMD and thought that I needed to update the graphics
driver. I installed the correct NVIDIA driver from their website. Now VMD
GUI won't start, it exits with the following message

It works in text mode but the OpenGL window is not starting.

Please help me sort this problem out.

Thanks,
