Yes, I have set VGL_DISPLAY before using vglrun. I'm on a 6 GPU box. The piece of software I'm writing (VizStack, mentioned below) dynamically manages the X servers. I see some mails in the list asking about how to use VirtualGL with multiple GPUs. VizStack will meet their needs on single nodes as well as on cluster of nodes.
VizStack maintains pools of X servers, so I end up with :15 ! I will try running mesademos/pbdemo.c.
