yes

📜 What is the name of the script you are using?

Channels DVR

📂 What was the exact command used to execute the script?

bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/ct/channels.sh)"

📝 Provide a clear and concise description of the issue.

I have tried a number of things and oddly.....the Plex LXC on the same exact host sees the iGPU fine but the channels one will not. That has be quite baffled. The host vainfo is good, the igpu_top sees the iGPU, Plex LXC (ubuntu) sees it, but this one will not. I am out of ideas to try. I did want to try ubuntu but that fails (see other issue about the chromium error)

I've tried privileged and unprivileged to no availl

no error but here is the vainfo output which matches the Plex container output and the host output....it's all the same.

So... What's the problem with the script here?

[ChrisColotti]

I can’t tell I just know the plex script sees the iGPU this one doesn’t. So hard to determine if something is missing in the channels script. By side by side comparison of one working and the other not I figured I’d start there.

I was going to try using the plex script and installing channels manually on it just to do a hack test but nothing I’ve tried with the channels script seems to allow it to see the same iGPU on the same host as the plex script was run on.

Since the host is the same the only variable to me is something different between the two scripts so was worth asking the question or seeing is someone else could try and get the same result.

[ChrisColotti]

Happy to move this to the discussion section if there’s no issue with the scripts. Just trying to get it to work the same as plex is on the same host.

[ChrisColotti]

I just tried using the plex installer script, removing plexmediaserver with apt and installing channels, and still no joy on this...so I'm at a loss for testing and workarounds.

[ChrisColotti]

for the record it turns out you need this options specifically in PVE for the channels container to pickup the iGPU

echo "options i915 enable_guc=2" > /etc/modprobe.d/i915.conf

Also in my case PVE picks up /dev/dri/card1 and you can symlink it to /dev/dri/card0 which is what that app defaults to and will only search for.
