DESCRIPTION: .sh super simple script to run a command when Lock Screen is activated (aka system's idle/ I'm afk) because I'm a programming noob. Only tested with a desktop environment (gnome) in Pop!_OS. It detects when the lock screen activates and runs the script, then when the lock screen is deactivated and the user is back, it "pkills" the script. Has a annoying bug that makes the script run when the computer starts which I don't know how to resolve... I'm a noob, so if anyone sees this and wants to give me some advice on how to make this work better, I'm all ears!
