How to have GPU-based rendering in docker console? about docker-nvidia-egl-desktop HOT 5 CLOSED

Finally got it running. I need to set these env variables:

export VGL_REFRESHRATE=60
export VGL_ISACTIVE=1
export VGL_DISPLAY=egl
export VGL_WM=1

from docker-nvidia-egl-desktop.

As a side note, the GPU rendering will stop working if I use root user instead, even when log in through webVNC:

user@351d9e1b605d:/opt/VirtualGL/bin$ sudo -i
user@351d9e1b605d:/opt/VirtualGL/bin$ ./glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
GLX FB config ID of window: 0x13d (8/8/8/0)
Visual ID of window: 0x3d0
Context is Direct
OpenGL Renderer: llvmpipe (LLVM 12.0.0, 256 bits)
71.574763 frames/sec - 79.877436 Mpixels/sec

from docker-nvidia-egl-desktop.

Please append vglrun to all commands that you want to accelerate. Since the Desktop Environment was run using vglrun in the first place, commands run from the GUI will work without them.
For example:
sudo vglrun glxgears -info

Looks like something I should add to the docs.

@ehfd Thank you for the reply! Here is what I got:

(base) user@351d9e1b605d:/opt/VirtualGL/bin$ sudo vglrun ./glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
GLX FB config ID of window: 0x13d (8/8/8/0)
Visual ID of window: 0x21
Context is Direct
OpenGL Renderer: llvmpipe (LLVM 12.0.0, 256 bits)
52.943677 frames/sec - 59.085144 Mpixels/sec

I suppose the rendering still happens on CPU? (I tried without sudo but basically, the output is the same as above)

vglrun glxgears -info in the console now works correctly without any additional environment variables.
