Display Origin Swap (dos)

Introduction

Display Origin Swap (dos) provides a workaround to the issue where Macs will randomly reverse the screen arrangement of identical external displays. dos uses the Displayplacer command line utility to swap the position of two displays.

• Runs 'displayplacer list' to extract current screen configuration.
• Runs 'displayplacer' with the correct arguments to swap the origin position of two displays.

Install Display Origin Swap

git clone https://github.com/kernelpanic19/display-origin-swap.git

Configure Display Origin Swap

Edit the displays_to_swap() tuple in dos.py if needed. This collection should contain the indexes of the two displays to swap. The indexes can be seen in the 'Detected screens' output of dos.py.

def main():
    displays_to_swap = (1, 2)

Install Displayplacer

Displayplacer is a macOS command line utility to configure multi-display resolutions and arrangements.

Alias

You may want to alias this script for ease of execution. Typing dos in the shell will execute this script. The example below will need to be modified for your environment and appended to your .bash_profile or .zshrc.

alias dos='python ~/code/dos/dos.py'
