[Lenovo Legion Slim 7] created a GUI for a rudimentary brightness controller since full brightness support isn't available. Only uses xrandr so not quite optimal but I'd been changing brightness through the terminal and figured this would be convenient for myself and others maybe
I think I used this one, seemed to work for me

The problem was with udev rules. It was not there for some reason

brightnessctl should be used without root permisions. Check how you can do it th the README: https://github.com/Hummer12007/brightnessctl. Depending on how you installed the package the udev rules could be already installed but you also need your user in the video group.

Am I tripping or is pop_os causing me a lot of eye pain after switching from windows?
What I did, was switch back to light mode everywhere (boy it was hard at first), turn brightness of the monitor all the way down and also dimming and warming the colors a bit with Brightness controller. The desired effect is actually something called sepia (mode that should imho be implemented along side light and dark modes). Basically dim yellowish background with nice and crispy black or dark gray font.
