Native you mean the deb package correct?

drwxr-xr-x 3 root root           100 Feb 18 15:51 dri

crw-rw---- 1 root video  226,   0 Feb 18 15:51 card0
crw-rw---- 1 root render 226, 128 Feb 18 15:51 renderD128

For the deb package in Debian I would just

su -
dpkg -i plex_package_here.deb

I would normally not do anything else than that?

  1. By native, yes I mean the dpkg -i packagename.deb method

  2. when it comes to /dev/dri, you have two groups which is uncommon
    (there appears to be no udev rules active yet)

  3. After the native package is installed, /dev/dri becomes more more uniform.

[chuck@lizum Downloads.2042]$ ls -la /dev/dri
total 0

  1. The installer adds user plex to the render group for you.
  2. When PMS starts, it will have the privileges to access the hardware.

  • Stopped the podman plexmediaserver service
  • Downloaded and installed the latest plex media server package
  • changed ownership of /opt/plex to plex:plex
  • setup the override.conf and restarted the service
  • played the same movie Iā€™ve been testing and its still doing the buffering :confused:

/dev/dri now is render for both card0 and renderD128

Switched back to the podman image and then updated my grub to force the load of the xe driver.

GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.force_probe=!7d67 xe.force_probe=7d67"

Now plex does not hw transcode lol

Wanted to see if using the xe driver would make a difference.

I also havenā€™t had any luck with xe driver which seems to be required for Battlemage GPUs. Will have to wait for official support.

26

I have a RTX 3060 TI lying around that I might have to throw in there to see if it can handle everything until better support comes around. My fault for buying the latest CPU and expecting it to work lol
