You practically need to interface with some desktop environment and some display server . On Linux that could be Xorg or Wayland . So you should use some GUI toolkit (and they usually provide some event loop ). Read more about GTK & Qt . Both are interfaced to Python, with PyGTK or PyQt . Write first some simple GUI application (in PyGTK or PyQt) to understand the concepts.

BTW, xtrlock is free software , so you can study its source code for inspiration.
