I really feel like Linux distros should come with ddcutils preinstalled, and Gnome should build in some sort of functionality to control it, like this: https://github.com/daitj/gnome-display-brightness-ddcutil
Isn't having an external monitor really common? And when all laptops come with dedicated buttons for changing the display brightness, doesn't that suggest that people like to be able to easily adjust the screen brightness? Then why wouldn't we want to do it also on external screens?
