A small and dirty script utilizing GTK3 (PyGObject) to make all screens black(ish) except the one where the cursor is. Inspired by an xplayer feature. Hacked together in a few hours (i.e. I have no idea what I'm doing).
- I'd suggest assigning a keyboard shortcut to the (executable) Python file.
- Put your cursor on the screen you want to focus on.
- Execute the keyboard shortcut of your choice.
- Then you can binge your favourite content (or do something productive) without distraction from your other screens.
- Type something in one of the black windows this script opens to close all of them.
You can achieve similar results by using xrandr --output <name> --brightness 0. Unfortunately, on my setup the brightness resets after a few seconds. If you don't mind active windows being moved to another screen, you could also disable the screen completely: xrandr --output <name> --off.
