I'm trying to get this working but I don't see where the problem is. I
didn't have any *dm so I installed one to be sure that there is a
'real' X server running. Then I started vncserver from
/opt/TurboVNC/bin:
ps aux | grep X

When I try /opt/VirtualGL/bin/vglrun glxgears I obtain:
[VGL] WARNING: VirtualGL attempted and failed to obtain a Pbuffer-enabled
[VGL] 24-bit visual on the 3D X server :0. If the application
[VGL] subsequently fails, then make sure that the 3D X server is configured
[VGL] for 24-bit color and has accelerated 3D drivers installed.
I have checked and apparently the card supports pbuffers...so I'm stuck.
