Unable to Change GPU Ownership/Permissions in Linux - tacohell - 2025-04-11
This is more of a Linux question if anyone has experienced this problem
I'm running Jellyfin in a Proxmox LXC container. I've already passed through the Intel iGPU and Jellyfin is a part of the render group.
ls -l /dev/dri
crw-rw---- 1 nobody _ssh 226, 128 Feb 14 15:54 renderD128
For some reason renderD128 does not have an associated user and group. When running chmod or chown I get this issue:
sudo chmod 666 renderD128
chmod: changing permissions of 'renderD128': Operation not permitted
Not sure why I can't change this with sudo, or even change ownership to root

Is the LXC privileged?
RE: Unable to Change GPU Ownership/Permissions in Linux - tacohell - 2025-04-11
LXC was unprivileged, but I found what the issue was.
I had to change permissions on the proxmox host of RenderD128. Once changed there, the LXC permission was the same:
crw-rw-rw- 1 nobody _ssh 226, 128 Feb 14 15:54 renderD128
Even though it still doesn't have an owner, transcoding is working now.
RE: Unable to Change GPU Ownership/Permissions in Linux - TheDreadPirate - 2025-04-11
This is not recommended. The permissions you manually set on renderD128 will revert when you reboot the system.
Our documentation recommends that you run the LXC as a privileged container.
https://jellyfin.org/docs/general/administration/hardware-acceleration/intel/#lxc-on-proxmox
But I know it is possible for the LXC to be unprivileged, but requires a lot of user mapping between the host and LXC.

Got it, I'll try that instead. Thanks
