linux-idletimer

A simple IDLE timer for any linux system whether it has a DE or it's headless

---

Because I have seen there is no easy way to detect system being IDLE without using Xorg or Wayland which actually mostly will not be a solution, for example when trying to see if system is Idle using from another user on Xorg it will fail, I came with this simple idea to read /dev/input/event* for any events the user perform, this will include keyboard or mouse movements, and it's easy to copy-paste this implementation to any codebase.
