Hardware Acceleration no longer working - Reflector3718 - 2025-08-08
Hi I have the problem that after an update on my proxmox my hardware acceleration (JElly is in an LXC) is no longer working. I tried a lot namely this guide (https://forum.jellyfin.org/t-proxmox-lxc-with-nvidia-transcoding-and-network-share which i used the last time) but cant get it working again.
Maybe someone knows why it happens here is all the informaion i collected so far:
In the COntainer the GPU is existing:
