# This script is intended to make switching between laptop and external displays easier when using i3+dmenu | |
# To run this script, map it to some shortcut in your i3 config, e.g: | |
# bindsym $mod+p exec --no-startup-id $config/display.sh | |
# IMPORTANT: run chmod +x on the script to make it executable | |
# The result is 4 options appearing in dmenu, from which you can choose | |
# This is your default laptop screen, detect by running `xrandr` | |
INTERNAL_OUTPUT="LVDS-1" | |
# choices will be displayed in dmenu | |
choices="laptop\ndual\nexternal\nclone" | |
# Your choice in dmenu will determine what xrandr command to run | |
chosen=$(echo -e $choices | dmenu -i) | |
# This is used to determine which external display you have connected | |
# This may vary between OS. e.g VGA1 instead of VGA-1 | |
