feat:add virutalgl for hardware accelrated opengl

[vajonam]

Add support for virtualGL.

This however means you need to get VirtualGL supported on the host this involved the following

• installing simple X server
• installing virtualgl and running vglserver_config

Once the X server is up and running. Then this container will with fully accelerated

@helfrichmichael its in a decent spot now. This approach with VirtualGL it need a Xserver and VirtualGL running on the host (which can be headless). And we will need to make that a pre-req. We will have to document steps to get that going. I tried so many things so need to understand what I did from a docs perspective. But folks who already are using Xsever this should be quite easy.

Need a solution for firefox, because in 22.04 it runs from snapd, and I can't be bothered to get snapd to work inside a container for now that is missing.

Interestingly, I cannot get the GPU (NVidia RTX 3070) to passthrough with NVidia + WSL2 + Docker on Windows. Using the benchmark in https://docs.docker.com/desktop/gpu/ works just fine though.

Command I'm using to start it: docker run --detach --volume=prusaslicer-novnc-data:/configs/ --volume=prusaslicer-novnc-prints:/prints/ -p 8080:8080 -e SSL_CERT_FILE="/etc/ssl/certs/ca-certificates.crt" -e ENABLEHWGPU=true -e NVIDIA_DRIVER_CAPABILITIES="all" -e NVIDIA_VISIBLE_DEVICES="all" --name=prusaslicer-novnc prusaslicer-novnc

Wondering if I've done something wrong to cause the GPU to not passthrough?

You might need to set permissions on the card on the host.

In the VirtualGL package there is vglserver_config tool you can run and select EGL and select N on the permission options. Give that a try. That is a useful tool to setup the card and driver on the host.

Also I am not sure how nvidia implements EGL in windows drivers. You need to check about that.

Also make sure you can read /dev/dri/card0 from inside the docker container this is that vglrun uses. So that's the first place to look along with the tool I mentioned above

[vajonam]

The GPU benchmark is testing out CUDA cores which are differnt from the EGL features virtualGL uses. AFAIK. I am no expert just got into this a few days ago!

[vajonam]

added code to launch firefox-esr as accelerated if ENABLEHWGPU is set.

[helfrichmichael]

Sorry again for the delay. I'll be reviewing and merging this tonight after work. It's been a busy few days.

[helfrichmichael]

Super sorry for the delayed review! Merging now and we'll address any bugs along the way. Thanks again!
