I run arch with bspwm on a Lenovo a275 using amdgpu drivers and i am very new to linux. I can adjust screen brightness with the xrandr --output MONITORNAME --brightness VALUE command.
This works fine on battery and with the charger connected. But when I plug/unplug the charger the screen dims significantly, and it cannot be brought up to full brightness with the above xrandr commands. Also the same values for above command produce different (noticeable less bright) results.
The screen also dims when I am still in tty. In tty I assume those xrandr commands are useless anyway, just noted that the dimming happens too without x running.
Using values greater than 1.0 to force more brightness after I plug/unplug results in higher contrast, but not higher brightness.
Rebooting brings everything back to normal, but it is annoying to be forced to do this. Is there a way I can "reset" my screen brightness to normal from the cli or stop the system to adjust screen brightness automatically every time plug or unplug?
