As far as I know, there’s no version of intel graphics that can use both i915 and Xe. Your processor only has 1 set or the other. The 2 drivers support different graphics cards/igpus. If i915 loads, then you have one of the older iGPUs. Xe is for Battlemage cards and specific new gpus that have ARC B-type iGPUs.
I’m not the right person to help. I’ve never used Proxmox, LXC containers, or systems with ARC graphics. No idea how to configure passthrough for GPUs, etc.
AFAIK, the hw transcoding should work on the 285T. It has Alchemist graphics, the same as the ARC A cards, which are successfully used with Plex (based on other posts in the forum).
Definitely try PMS 1.43.1.10540, released earlier today. In addition to Battlemage support (which you do not need), it will have the latest Intel CPU IDs. The 285 has been out for over a year, so it will be included in the build (I’m not saying it wasn’t included earlier just that it will be in the current beta).
Hopefully others can assist with the specifics on setting up Proxmox, et al.

My cpu has XE-Arc , new arrowlake cpu.
I need to enable xe driver in grub in Proxmox which works fine . But making the Ubuntu use xe seems a be a problem 
Thanks for the reply 
Appreciated
Were not things working in November? Where do I find which CPUs that is supported by Plex? - #11 by Morphy
Either way, suggest you open a new thread and mention Proxmox and the 285T in the subject line. That should draw attention from people with similar setups.

Yes working but with i915
Will post a new thread tomorrow
Thank you
Arrowlake uses Arc-A which uses the i915 driver, not the Xe driver. I think you are confused because Intel calls them Xe cores, but the linux Arc-A type graphics cards and older use i915 driver, the Arc-B cards.. like the B50 and B580 use the new Xe driver. You can’t make the xe driver work on an arrowlake iGPU.

Hi.
You are probably right .
Have to read more up in this .
Thanks again
I just tried to load xe driver for the pve host. Works fine - next I went t to my container
This is my normal vainfo :
vainfo
error: can’t connect to X server!
libva info: VA-API version 1.20.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_20
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.20 (libva 2.12.0)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 24.1.0 ()
vainfo: Supported profile and entrypoints
After changing grub to load the xe driver - I get load error on the plex container
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/xe_drv_video.so
And that driver is not located , I only see:
d3d12_drv_video.so i965_drv_video.so iHD_drv_video.so nouveau_drv_video.so r600_drv_video.so radeonsi_drv_video.so virtio_gpu_drv_video.so
Don’t know if there is a work around?
Nice! I tried last version (1.43.1.10561) on my docker install.. cleaned a bit and voilà! after so many years : HW Transcode is working on my j5005 with tone mapping. Congrats everyone and thanks
I have successfully installed the Plex Media Server version 1.43.1.10495 Chris Decker provided on Feb 6th. It works on Ubuntu version 24.04.4 with the Intel Arc B50! It transcodes up to 12 4k streams simultaneously no problem! However, this version appears to have some compatibility issues with different types of players. It works great with ROKU, Google TV, Apple TV and the Windows 11 app!
On the LG web OS app, android app and iOS app it says server offline. So there appears to be some type of combability issue with Plex Media Server version 1.43.1.10495 and the newest versions of the app on many platforms.
