For some reason I can only change the backlight of the monitor (iMac 2013 21inch) with the Linux kernel 5.4LTS.
I tested several different versions (LTS and non-LTS) and was unsuccessful.
Would anyone have any idea where to start?
I have already tested xbacklight and other commands with xrandr on the terminal and I was not successful.
I believe it is some driver problem.
Linux 5.12.6-arch1-1 (ArcoLinux)

Thank you all for your attention!
Hi @brunnovert, and welcome!
I’m of opinion that if an LTS kernel works (as you said yours does) one should not change unless a newer kernel has a feature you require.
However, I did a quick bit of searching, and came across this. It might help. Although, it also might not.
But, I hope it helps!
I think it is easier to stick with LTS.
I hope it won’t be discontinued anytime soon hahahaha
Thank you bro
Accordig to Wikipedia it’ll be supported until December 2025.
So I’d say you’re quite safe.
This is the Manjaro support forum, not the ArcoLinux support forum. Are you lost?
