Yes im running Jellyfin in a Ubuntu VM in Proxmox.

Jellyfin 10.8.12 (server)
Intel® Core™ i5-7400 CPU @ 3.00GHz (1 Socket)
8 gb DDR3 RAM
Ubuntu 22.04.3 LTS

Should I enable something on proxomox to initialize the Intel GPU?

Let's backup a bit.  Is the Ubuntu VM the only VM you have or plan to have?  If this is your only VM, maybe we should consider just going with Ubuntu bare metal to not needlessly complicate your setup.  There have been a lot of Jellyfin users here that had single VM setups with no plans for additional VMs that we convinced to just go bare metal.

But if you have, or plan to add, additional VMs then you will need to pass the GPU into the VM.  Then setup the GPU with these steps.
