I'm trying to setup a headless plex server with hw acceleration on FreeBSD 13.1-RELEASE-p6. I installed drm-510-kmod and gpu-firmware-kmod with all the intel modules. kldstat shows both i915kms.ko and drm.ko as loaded.
Currently, I have kld_list="i915kms" in rc.conf and drm_load="YES" in loader.conf.

dmesg drm output:
Code:

glxinfo gives this error:

Any feedback is appreciated.
 
Please post your log: cat /var/log/Xorg.0.log | nc termbin.com 9999

Note that glxinfo requires to be run from inside a working X session. The 'error' you're seeing is a failure to connect to that X session. Which likely isn't running as this is supposedly a "headless" system.
 
Yes, my bad. It is headless, so I didn't install any X environments, hence that log file is absent. I also tried ffmpeg and I think it works both on host and inside plex jail. At this point I think the issue might be with plex.
Thanks for the reply.
 
Oh well, it seems to be an user permission issue, because changing the plex jail user to root fixes hw acc.
Sorry for starting this thread. I thought I tried everything...
 
Well, you don't want to run plex as root for obvious reasons. With X a user needs to be a member of the video group. So I would make that 'plex' user a member of 'video' and see if that works.

For access to /dev/drm/ devices, the user should be a member of the video group.

That was the way it was initially set up. I created an user and added it to 'video' group. Not sure what went wrong, I will try again. Thank you for your time.
 
To use hardware acceleration, I believe it states that very clearly that the plex user must be member of the video group in the message that is displayed after the installation of plex.
