Hi,
  What version of the NVIDIA drivers are you running on this
machine? The warnings about /dev/nvidiactl seem to indicate
that there's something wrong with your driver installation.
This is also indicated by the GLSL warnings later on.

Also, you're going to want to switch from beta 1 to beta 5
as there are various (unrelated to your current problem) bug
fixes since then. I would recommend that you get the latest
NVIDIA drivers and install them, and that you delete the old
test version of VMD and use the new beta 5 version. Try that
and let us know if you need more assistance.

Cheers,
  John Stone
