    Check out Clight. There's also a GUI for it.

    The only downside to Clight? You need to build not only Clight and Clightd from source, but also 2 dependencies (libmodule and ddcutil), as well as the Clight-GUI if you want to use it. That is, unless you use Arch Linux / Manjaro (there are AUR packages available), NixOS, Exherbo or Void Linux, for which there are packages available.

    This is not hard to do - the instructions are there - just follow this guide. Every command you need to type is written

    Or you can use Clight (disclaimer, i am the author!) and let it do the magic for you :) It uses ddcutil C library to support external monitors too.

    Clight (and others, actually) does exactly this

    This approach sounds similar to clight, which uses a webcam to adjust backlight levels (so may be a little less fidgety than using a color calibration sensor):
