Hi,
  Beyond the suggestions others have mentioned, you'll also want to
check and make sure that the X windows server you're using supports
GLX protocol, and that the machine you're running VMD on is able
to attach and create a GLX context. If the VMD host machine is
on Linux (for example) you can use the 'glxinfo' command to check
that the X server supports GLX OpenGL remote display protocol.
