Dear John,

I have noticed that VMD as well as glxinfo works fine as sudo user and root
user. Unfortunately, glxinfo showed following error with regular user and
the VMD also failed. It looks the issue is with environment variable. Can
you please advice me how to set this up?

As regular user:

$ glxinfo
name of display: :0.0
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request: GLXBadContext
  Major opcode of failed request: 153 (GLX)
  Minor opcode of failed request: 6 (X_GLXIsDirect)
  Serial number of failed request: 46
  Current serial number in output stream: 45

As sudo:

sudo glxinfo
[sudo] password :
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
