VMD-L Mailing List

Hi,
  Interesting. It seems that your video driver is not advertising
_any_ of the OpenGL shading language extensions. The "Features" line
printed by VMD doesn't include any of the programmable shading extensions.
In a normal run on a machine that has all of the OpenGL extensions, you
would see "GLSL(OVF)" toward the end of the OpenGL features string
printed by VMD.

Since you mentioned that you previously did have GLSL working on this
hardware, the most likely cause of problems is that your system's
OpenGL libraries or video driver version has been changed to one that
is less capable than you had previously. Can you email me the output
of "glxinfo" on this machine? I will be able to determine more about
your video driver and OpenGL library based on the output it prints.

Thanks,
  John Stone
