Updated my Ubuntu server last night to 19.10 and today I am only transcoding via CPU. I tried restarts and I have confirmed it is still seeing the CPU as the default GPU. My system is a Dell Optiplex 5050 running an i5-7500T. Nothing has changed in Plex aside from updated Ubuntu. Wondering if anyone is having the same issue and if there are any fixes aside from wiping and going back to an old version. Thanks.
You probably need to reinstall the appropriate video drivers. Any time the kernel is updated.
Please give me the output of ls -l /dev/dri
drwxr-xr-x 2 root root 80 Nov 3 22:04 by-path

The group was changed by Canonical to render in Ubuntu 19.10. Add user plex to the render group and HW transcoding should function again.
when I do ls -l /dev/dri i get ls; cannot access ' /dev/dri': No such file or directory
Are you running Ubuntu 19.10 as well?
If /dev/dri is not being created by the kernel at boot,
then it’s not seeing any QSV or graphics cards which might be usable.
Probable causes:
- Not a X86_64 installation of Ubuntu
- PMS installed in a VM or container which hasn’t had the directory passed through
- CPU isn’t capable (e.g. most Xeon CPUs)

Given it is the weekend, and this issue was raised Friday,
I do not expect any feedback from any of the team until US monday.
