Hi,
We have a bunch of centos 7.2 workstation with geforce cards in them. I
configured VNC + VGL on them and they work fine (both through VNC sessions or
by vglconnect). So all is good there. These are not headless, but used
interactively.
I have a different workstation with two GPUs in them. one GPU is a NVS card, to
which the monitor is attached and there is a headless geforce. There is no X
running on the NVS. I installed the nvidia drivers, vnc, and configured the
VGL. But when I connect through vnc and run vglrun +v glxinfo I get
Xlib: extension GLX missing on display :0 error
Couldn't find RBG GLX visual or fbconfig.
Can someone provide some pointers on how to do the configuration appropriately?
This is a test bed for a server that will have an onboard graphics card and a
headless GPU (or two) to serve users 3D applications.
