SOLVED: Problems during intel arc gpu settup

[thatscringebro]

I have recently acquired an Intel Arc A750 and I would like to use it for hardware transcoding on my server. Firstly, I am using debian 12 with kernel 6.10.11 and jellyfin runs on the os, not in docker. Every package is up to date and jellyfin runs as it should for now.

I have followed the hardware transcoding setup steps according to this guide: https://jellyfin.org/docs/general/admini...nux-setups and get an error on step 8.

Here is the output of the command:

Code:

I know my card is well detected by the system and shows up in /dev/dri:

Code:

# ls -l /dev/dri
total 0
drwxr-xr-x 2 root root        100 Dec  4 09:00 by-path
crw-rw---- 1 root video  226,  0 Dec  4 09:00 card0

crw-rw---- 1 root render 226, 128 Dec  4 09:00 renderD128

And vaininfo seems to output the appropriate data:

Code:
