I have a nvidia 1650 graphic card on my legion-Y540 with ubuntu 20.04 I had fixed my brightness issue(Function keys not working) by adding Option "RegistryDwords" "EnableBrightnessControl=1" in the device section of /etc/x11/xorg.conf
It worked perfectly well until a software update, then now method worked, and I am only able to adjust brightness with the help of brightness controller, but in that I cannot use night mode, cause it sets the brightness to maximum only, whenever I use that.
