Poor Man’s’ Ambient Light Sensor for Linux

For those poor laptop owners (like me) who lack an ambient light sensor, or those whose sensor is broken on Linux, I've developed a solution: It uses your camera as a light sensor to adjust your laptop's screen brightness, eliminating the need to constantly fiddle with the brightness menu. Don't worry, it doesn't save images to disk (you can easily pick your nose 😀). It simply checks the pixel brightness and adjusts the screen. It worked flawlessly on Fedora 43.
