Hi,
  The output of glxinfo indicates that your driver isn't exporting
the GLSL extensions. In fact, the only extra features you're getting are
the multitexture extension and a stencil buffer. It appears that you're
attaching through 'ssh', guessing by your DISPLAY variable being set
to "localhost:10.0". That combined with the fact that you appear to be
remote displaying onto a remote laptop may be the reason for problems.
What happens when you run VMD locally on the laptop? (the machine with
the Quadro FX Go1400 in it, which I'm assuming is NOT the Altix...)

Cheers,
  John Stone
