Clight is a C user daemon utility that aims to fully manage your display.
It will automagically change screen backlight level to match ambient brightness, as computed by capturing frames from webcam.
Moreover, it can manage your screen temperature, just like redshift does.
Finally, it can dim your screen after a timeout.
It was heavily inspired by calise in its initial intents.
For a guide on how to build, features and lots of other infos, head to Clight Wiki Pages.
