If you plug in your monitor you should be able to automatically get the config you want
|
|
First write a script that does that for 'xrandr'
|
|
|
|
#! /usr/bin/env bash
|
|
export DISPLAY=:0
|
|
export XAUTHORITY=/home/dan/.Xauthority
|
|
|
|
function connect(){
|
|
xrandr --output HDMI-2 --same-as eDP-1
|
|
}
|
|
|
|
function disconnect(){
|
|
xrandr --output HDMI-2 --off
|
|
}
|
|
|
|
xrandr | grep "HDMI1 connected" &> /dev/null && connect || disconnect
|
|
|
|
|
|
And now create a udev rule to listen to it
|
|
For [[nixOS]] this would be services.udev.extraRules
|
|
|
|
KERNEL=="card0", SUBSYSTEM=="drm", ENV{DISPLAY}=":0", ENV{XAUTHORITY}="/home/anish/.Xauthorit y", RUN+="/home/anish/bin/hotplug-monitor.sh"
