command line - Script / Shortcut to switch display priority? - Ask Ubuntu

i wish have shortcut switches priority (i.e. primary, secondary) of displays (laptop + external).

ps: aware there's dedicated button/shortcut but, @ least mine, cycles through configurations (i.e. different resolutions). want cycle between 2 configurations only.

it turned out wrote it, part of this question. since another question, below outtake of one:

#!/usr/bin/env python3 import subprocess  # set primary screen, set other 1 scr_data = subprocess.check_output(["xrandr"]).decode("utf-8").splitlines() scrs = [[l.split()[0], "primary" in l] l in scr_data if " connected" in l] screen in scrs:     if not screen[1]:         subprocess.popen(["xrandr", "--output", screen[0], "--primary"]) 

it toggles (switches between two) primary screen.

to use:

• copy script empty file, save toggle_primary.py

• add shortcut key: choose: system settings > "keyboard" > "shortcuts" > "custom shortcuts". click "+" , add command:

  python3 /path/to/toggle_primary.py
