How to render with GPUs in VNC Desktop

[oldraincoat]

Thanks for sharing the code
I am running the container on a remote host and I want to display the window of glxspheres64
with virtualgl on GPUs.
I start the docker container with:
nvidia-docker run -d -p 8888:8888 -v /home/$USER/work/work1:/home/jovyan -e JUPYTER_ENABLE_LAB=yes nvaitc/ai-lab:19.09-vnc
And I start the vnc desktop and run the following command：
/opt/Turbovnc/bin/vncserver :5
vglrun -d :5.0 ./glxspheres64
But the result shown in the figure illustrates that opengl renderer is llvmpipe, not GPUs.

How can I render with GPUs and display the window.
Thank you.

Apologies for the delay, I have updated the FAQ with more detailed instructions. Here's the gist of it:

xhost +local:root
nvidia-docker --rm run \
 -e "DISPLAY" \
 -v /tmp/.X11-unix:/tmp/.X11-unix:rw \
 -p 8888:8888 \
 -v /home/$USER:/home/jovyan \
 nvaitc/ai-lab:20.03-vnc

Hi, this is the error I am getting.

Do you have any idea what I'm doing wrong?

I am trying to run this from a headless server, and when I run xhost +local:root I get this error:

➜  ~ xhost +local:root
xhost:  unable to open display ""
