For some reason, my laptop (Samsung galaxy book 12) refuses to let me change the screen's brightness. I've tried about every option I've seen online (changes in .conf files, new dev rules, xrandr/brightness controller, etc) but nothing works and I guess there isn't much more I can do about it.

Unfortunately that doesn't stop the screen from burning my eyes and giving me headaches, even with Ubuntu's night mode turned on... My question is, does anyone know if there's a way to artificially darken my screen? Some kind of dark filter I could apply so it makes it a bit more bearable? Thanks in advance!

Update in case anyone ends up in the same situation as me.

I've been able to fix the issue thanks to icc-brightness. I can select a brightness level with my keyboard's brightness keys, and make the change effective on the screen with ./icc-brightness apply. I'm assuming the OLED screen was the real issue all along.
