The brightness adjustment keys on my laptop work out-of-the-box on ubuntu 18.04's default desktop environment. When I install a new desktop environment, they no longer work. I'm able to install additional software to restore that functionality, but I want to know what library or application in ubuntu's default installation controls screen brightness.
This is not a duplicate of How do I adjust screen brightness when using a different environment from GNOME/Unity on Ubuntu 18.04? because I want to know specifically what ubuntu 18.04 is mapping the screen brightness adjustment keys to by default.
