is `plex` a member of the group which owns the video adapter ? What you show is common when it’s not and cannot communicate with the card ```auto Last login: Sat Dec 23 19:23:41 2023 from 192.168.0.13 [chuck@glockner ~.2001]$ groups plex plex : plex video render [chuck@glockner ~.2002]$ ls -la /dev/dri total 0 drwxr-xr-x 3 root root 120 Dec 21 13:17 ./ drwxr-xr-x 21 root root 5860 Dec 21 13:17 ../ drwxr-xr-x 2 root root 100 Dec 21 13:17 by-path/ crw-rw---- 1 root render 226, 0 Dec 21 13:17 card0 crw-rw---- 1 root render 226, 1 Dec 21 13:17 card1 crw-rw---- 1 root render 226, 128 Dec 21 13:17 renderD128 [chuck@glockner ~.2003]$ nvidia-smi Sun Dec 24 00:32:30 2023 +---------------------------------------------------------------------------------------+ | NVIDIA-SMI 535.129.03 Driver Version: 535.129.03 CUDA Version: 12.2 | |-----------------------------------------+----------------------+----------------------+ | GPU Name Persistence-M | Bus-Id Disp.A | Volatile Uncorr.

I had to install the package libnvidia-encode1\_470.199.02-1\_amd64.deb, It works perfectly now. ![putty_VcV9E10G2U](https://global.discourse-cdn.com/plex/original/4X/4/5/2/452335a935aa53a70e0195a1cfa214ce1148809c.png) I will let this documentation is people have the same error as I had [libnvidia-encode1\_470.199.02-1\_amd64.deb Debian 11 Download (pkgs.org)](https://debian.pkgs.org/11/debian-nonfree-amd64/libnvidia-encode1_470.199.02-1_amd64.deb.html) [NvidiaGraphicsDrivers - Debian Wiki](https://wiki.debian.org/NvidiaGraphicsDrivers#Debian_Unstable_.22Sid.22) Debian 11 official only official supports up to driver Version 470.129.06 for now ---

Yeah I don’t know what happened there, I did it through apt with `apt install nvidia-driver firmware-misc-nonfree` and the decode one installed correctly but not the encode one. Thank you and merry Christmas to you @ChuckPa ---
