SOLVED: "Playback failed due to a fatal player error." (Only in Firefox)

Did you setup low power encoding?

https://jellyfin.org/docs/general/admini...e-on-linux

Also, since you're using a backport kernel, did you also install all the kernel header, module, and firmware packages?

My apologies for the late response, but when trying to follow the steps in the link you sent, I'm stuck on step 4.
When using sudo dmesg | grep i915
I get the following:

Code:

And when using:

Code:

sudo cat /sys/kernel/debug/dri/0/gt/uc/guc_info
sudo cat /sys/kernel/debug/dri/0/gt/uc/huc_info

And

Code:

sudo cat /sys/kernel/debug/dri/1/gt/uc/guc_info
sudo cat /sys/kernel/debug/dri/1/gt/uc/huc_info

And

Code:

sudo cat /sys/kernel/debug/dri/0/i915_guc_load_status
sudo cat /sys/kernel/debug/dri/0/i915_huc_load_status

I get the following:
"No such file or directory"
When using ls in the /sys/kernel/debug/dri/ I get:

Code:

lrwxrwxrwx  1 root root 0 Oct 21 00:51 0 -> 0000:03:00.0
drwxr-xr-x 16 root root 0 Oct 21 00:51 0000:03:00.0
lrwxrwxrwx  1 root root 0 Oct 21 00:51 128 -> 0000:03:00.0

Any suggestions on what I'm doing incorrectly?

Kind regards

P.S. My apologies for my incompetence.
