Default NVIDIA/Linux setup for VirtualGL on node with no monitor

I was wondering if anyone has a NVIDIA card setup on a Visualization node
that does not have a monitor.

We have a M2070Q on a Viz node for remote graphics via VirtualGL/TuboVNC
and this configuration works without a problem from one workstation to another

The main differences are:
1. Use of the M2070Q on the Viz node
2. Monitor on the workstation and booting to X11

Both are running the same NVIDIA 290 driver (but i have also tried the 270).

I was not sure if I was missing something with the M2070Q configuration
or some special settings.

Here is what I see from vglrun with trace:

vglrun +tr -d :1 glxspheres64

vglrun glxinfo -v
Just returns the; lib: extension "GLX" missing on display ":1.0"

Any hints would be appreciated.
