VMD-L Mailing List

Hi Ryan,
  I bounced a copy of your reply to VMD-L so that others using VMD on
MacOS X and and/or with XQuartz can see it as well. The errors you get
when you run 'glxinfo' and 'glxgears' on the remote linux machine indicate
that the XQuartz window server on your Mac is (for some reason) failing to
respond to GLX protocol requests being performed on the remote Linux system.
GLX is that part of OpenGL responsible for managing graphics resources
and negotiating how the OpenGL framebuffer is mapped onto the
windows and shown on the physical display. I'm most concerned with the fact
that 'glxinfo' doesn't run, since that is the simplest test of whether the
X server has an operable OpenGL interface, and that is failing too.
I note that your libGL implementation on the Linux server is emitting
some errors about "failed to load driver: swrast", which makes me wonder
if the OpenGL system software on your Linux machine is complete or if there
are some software components missing. It is possible that the source of
trouble is actually the Linux machine rather than the XQuartz server,
but you may be able to determine that better based on what configurations
had worked for you in the past vs. the specific details of the software
configurations you're trying to use here. Did a previous version of
XQuartz work properly with the same Linux system? Does a different Linux
system work with this XQuartz version? Is XQuartz the only thing that
changed vs. the setup that had worked previously?

Cheers,
  John Stone
