Edit: For those who stumble across this with the same issue, I eventually got it working by adding “default-runtime”: “nvidia”, to /etc/docker/daemon.json then restarting the docker service and Jellyfin container.
I am in the process of setting up a new media server on an old PC using Ubuntu Server and CasaOS and have run into my first major roadblock.
To give some background, I formerly had my media server running on my main gaming PC on Windows using Plex and the *arr suite. I’m now trying to do things the right way and set everything back up from scratch on some spare hardware with Jellyfin and all the rest in dockerized containers. I chose CasaOS because I’m not overly familiar with Linux and thought that would be a good way to ease into things.
Everything was going well until I tried to get hardware acceleration enabled in Jellyfin. For the life of me I cannot seem to get the Nvidia drivers properly installed, much less give Jellyfin access to the device. I’m using a GTX 960.
I’m not sure exactly what additional info I need to give here, but here’s something I hope helps:
*****@home-server:/$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
*****@home-server:/$ nvcc --version

If there’s anything important I’m leaving out - and I probably am - let me know. Also if there’s anywhere else you recommend I post this let me know that as well.
This is such a common pitfall that even self-described communists fall into it as well. When you hear people talk about a "dictatorship of the proletariat," what they're describing tends to devolve into "a class of intellectuals needs to guide the working class to the correct decisions" when questioned about what a "dictatorship of the proletariat" actually entails. Often they'll try to justify it by saying it's only temporary, but we all know how that pans out (see the USSR). This is why I consider myself an anarchist rather than a communist and regularly critique marxism-leninism.
