Set Polybar on 2 screens

  1. Config
  2. launch.sh

Config

In ~/.config/polybar/config
Wat is your bar, by default it's exemple, but mine is Bar.
You should add monitor.

[bar/Bar]

monitor = ${env:MONITOR:} 

launch.sh

In ~/.config/polybar/launch.sh
Add this.

if type "xrandr"; then
  for m in $(xrandr --query | grep " connected" | cut -d" " -f1); do
    MONITOR=$m polybar --reload Bar &
  done
else
  polybar --reload Bar &
fi

To avoid 2 bars on the main screen comment the line you used to launch it.

#polybar Bar 2>&1 | tee -a /tmp/polybar1.log & disown
