Not having accelerated 3D drivers installed is the most obvious cause of that VirtualGL error message. Just because GLX exists doesn't mean that Pbuffers are available. In general, you have to install the vendor drivers for the 3D graphics card in order to get Pbuffers. The output of '/opt/VirtualGL/bin/glxinfo -display :0 -c' will tell you whether or not any Pbuffer visuals exist (look for a 'P' in the last column on any of the visuals.)
