No, that's not it. Hopefully someone with more knowledge on this than me can chime in at some point. I'm told that VirtualGL < 2.3.1 did not forward the glXCreateContextARB calls we need for creating OpenGL 3.2 context needed by ParaView (OpenGL2 backend).
To update my know how about it in the mean time, I read up a bit on TightVNC and VGL [1,2]. So, is your setup intended to use VirtualGL? If so, shouldn't you be running `vglrun paraview`? I believe that's the [VGL] warning messages are all about, aren't they?
