hi roland,
setting environment variables for VMD is done like any other
(shell) environment variable is set on a unix-oid machine.
please have a look at a unix tutorial if the abridged examples
below don't help you, or the nomenclature is not clear.
if you have a bourne shell (most likely on a linux machine):
VMDGLSLVERBOSE=1 ; export VMDGLSLVERBOSE
or if you have a c-shell:
setenv VMDGLSLVERBOSE 1
you can also set it only temporarily for the vmd invocation
(this is portable across shells and recommended for this case):
env VMDGLSLVERBOSE=1 vmd

my memory is a bit hazy and you'll probably get a
more authoritative answer from john, but if i remember
correctly, this graphics chipset does not support
full(!) GLSL at all, due to hardware limitations.
the driver itself seems to work. i'm using that version
successfully with a QuadroFX 4500 and with a GeForce 7800
on 64-bit and 32-bit linux, respectively.
cheers,
axel.
