Hey,

we need to run a Webbrowser inside of a Nvidia-docker container.
Therefore GL is needed (or it is going to be very slow).

The Solution with VirtualGL looks like it could work but I was not yet able to 
get GL-support inside of the docker-container.

The newest Nvidia-driver is installed on the host-system. A "nvidia-smi" tells 
me the docker-container has also recognized the GPU and has the newest driver 
installed.
Inside of the container I installed the mate-desktop-environment, virtualGL and 
Turbovnc. I can connect to the container via VNC and use it, but GL is missing. 
Typing "vglrun glxgears" returns:
Xlib: Extension "GLX" is mission on display ":0". Error: couldn't´t get a RGB, 
Double-buffered visual

"vglrun glxinfo" does kind of tell the same story besides printing the same 
message ~10 times.

After finding your opengl-branch I build my setup on top of it, but I still 
can´t get it to work.

Do I need to setup VirtualGl somehow?
Do I maybe need to install Xvfb? (I read about that somewhere but I didn't´t 
understand why it was necessary and how it would be used.)

I hope you can help me with this.

Best Regards
Joscha Knobloch
