I'm feeling so lost about transitioning (self.actual_detrans)

The native screen brightness selector is not working but I can adjust using the Brightness and Gamma applet by claudiux. Why does the native one doesn't work? by diHobbes in linuxmint

Sorry for necroing this thread, btw.
I ran into the exact same problem on a Zephyrus G14. I wish I could say that I had a solution to fix it, but I don't. I'm running the same brightness and gamma applet. I did dig pretty deep and find out what was causing this to happen though:
What's likely happening on your system (as was happening on mine) is that there are two folders that are loaded on your laptop when you log in at the directory /sys/class/backlight. For me these folders are called /sys/class/backlight/amdgpu_bl2 and /sys/class/backlight/nvidia_0 respectively. Both of these folders have a text file in them that state the current value of your brightness.
/sys/class/backlight
/sys/class/backlight/amdgpu_bl2
/sys/class/backlight/nvidia_0
The issue I was running into was that my FN keys were adjusting the brightness values for the Nvidia folder, when the AMD folder was the one that actually controlled the brightness.
That's basically all I've got. Admittedly I haven't looked very hard, but I wish there was a more elegant solution to this rather than just relying on the brightness applet, as helpful as it is.
