Persist display mirroring between laptop and external screen #4

Closed yannickperrenet closed 3 years ago

yannickperrenet commented 3 years ago

It should be able to handle it dynamically, since the screen might change in different setups.

xrandr --output DP-3 --same-as eDP-1

A shell script that uses the earlier specified command

xrandr --output DP-3 --same-as eDP-1

but determines the values for the displays through code instead of the values being hardcoded.

#!/bin/sh

xrandr_out="$(xrandr | grep '\sconnected' | cut -d' ' -f1)"
primary="$(echo "$xrandr_out" | head -1)"
secondary="$(echo "$xrandr_out" | tail -1)"

xrandr --output "$secondary" --same-as "$primary"
