Hi,
  This is indicative of some kind of problem with the GLX part of
the X server as is reported by the output from 'glxinfo' that you
listed below. I don't know what happened during your installation
of FFTW etc that you previously mentioned, but it clearly impacted
your graphics drivers in some way. You should revisit the graphics
driver installation, potentially removing and reinstalling them to
cure the problem if necessary. Until 'glxinfo' works correctly,
apps like VMD won't work right either.

Cheers,
  John Stone
