  Are you able to run "glxgears" on the remote Linux system?
If not, then VMD won't be able to run remotely either. You need to
ensure that your remote X11 setup supports GLX, which is what VMD
uses for OpenGL display. Otherwise, you may want to look at using
VNC, VirtualGL, or other remote desktop solutions that support
OpenGL applications like VMD.

Best regards,
