Just to double check, so we should be running 20.04 with the 5.4.0-107 kernel? I just did a fresh install and an apt update to make sure i have the right one for testing.
Thanks!
The 5.4 kernel is fine. I use 5.4 for production on my PMS server
I am using the HWE version of 20.04, which is currently on kernel 5.13.x and that works fine as well.
Cool, i have an 11xxx series proc so i wanted to make sure i’m using the correct kernel and have all the right packages so i’ve been going through the last few pages of message on this thread.
Thanks!
Hey Chuck… just wanted to ask - with Ubuntu 22.04 LTS literally being around the corner (I think the release is tomorrow), have you guys done any testing with that yet and does hardware encoding work there?
While I have you… and this goes to everyone in this thread: Does Fedora (server) have the same hw enconding/transcoding issues as Ubuntu?
Cheers!
Done some testing on it.
Doing some work. 
Make certain you’re still using ICR ver 21.49.21786.
I have a packaging change in the works (waiting on QA approval) and Engineering has their work in process now.

So, late to the discussion. I’m also on ubuntu 20.04, with a nuc11pahi70001.
CPU is 11th Gen Intel(R) Core™ i7-1165G7 @ 2.80GHz. It’s supposedly got an Iris XE “GPU” in it.
PMS installer is not detecting a GPU. Not sure if I need to override this in the configs or not. Anybody have any thoughts on this?
Thanks in advance!
Which distro & version are you using ?
The installer looks for the kernel to enumerate (show the existence of) the i915 interface.
Next, the transcoder looks for /dev/dri/renderD128.
Go look at /dev/dri. It should look like this:
[chuck@lizum ecpp.2016]$ ls -la /dev/dri
total 0
drwxr-xr-x 3 root root 140 May 13 15:48 ./
drwxr-xr-x 22 root root 5320 May 13 15:48 ../
drwxr-xr-x 2 root root 120 May 13 15:48 by-path/
crw-rw----+ 1 root render 226, 0 May 13 15:48 card0
crw-rw----+ 1 root render 226, 128 May 13 15:48 renderD128
[chuck@lizum ecpp.2017]$
On TigerLake, Ubuntu 20.04 and above, Intel Compute Runtime (all modules) version 21.49.21786 must be installed ( These replace the older Beignet/OpenCL and provide access to the QSV )
If the software is installed and the QSV is enumerated, make certain user plex is a member of the group which owns /dev/dri/renderD128.
(The installer will add ‘plex’ to the group for you)
Maybe that’s something that we can put in the official knowledge base, @ChuckPa? This page seems like a good place to put it (it seems a bit outdated anyway):
BTW: Ubuntu 22.04. experiments concluded? Safe to upgrade?
Experiments concluded.
Safe to upgrade ?
– Not certain. AlderLake is bleeding edge and not there yet (kernel deficiencies)
– Don’t know about TigerLake.
I’m doing a big overhaul of the installer now.
I’m adding the logic to pair the processor WITH the Distro + Version.
I’m doing it because everyone has something slightly different.
The installer should be smart enough to tell you which specific changes you need to make / modules which are missing or need updating.

I don’t have a /dev/dri folder at all. There’s no configuration in the bios specifically around the gpu either… I’m wondering if I need to flash the bios to enable support or something.
If you don’t have /dev/dri, please also confirm you don’t have QSV hardware transcoding ?
Also, which specific CPU are you using? Some Intel CPUs don’t have the ASIC.
Being honest, I have no idea how to validate the QSV question. The CPU is an 1165G7 (tiger lake).
From the link you provided.
Intel® Quick Sync Video - Yes
To validate if its being enumerated:

You’re looking for the PCI bus link which takes from the generic to the actual device.
Sincere thanks for the help here. I’m a little out of my depth.

Please retype the command exactly as I posted it (with the trailing /)
It will follow the symlink and show the directory contents (which is what we want).
At this point, it does appear to be finding the i915.
With you not getting the QSV module enumerated, I suspect there’s either a board limitation preventing it or UEFI/BIOS turning it off. Check if you can
my bad, see below: I checked the bios, and there’s nothing relevant based on the docs. The graphics related elements I could find are IGD settings (minimum memory, aperture size), and a setting for Gaussian Mixture Models and Neural Networks Accelerator.

Update your kernel. 5.4 isn’t going to cut it. You need the HWE kernel.
I think HWE started at 5.8. 5.13 is current for LTS
