swaybg-spread

A simple CLI tool to set wallpapers spanning over multiple monitors in sway.

It uses the Wayland output configuration to determine monitor size and position, and splits the provided image into separate images for each monitor. These are saved to ~/.cache by default. It then uses swaybg to set the images on the corresponding monitors. To persist the changes the program outputs sway configuration lines which can be written to a sway configuration file.

Originally forked off of 0xk1f0/rwpspread

Installation

Available from the AUR:

yay -S swaybg-spread

Usage

Set wallpaper spanning all monitors once:

swaybg-spread -i ~/some-wallpaper.jpg

Set wallpaper and write it to a sway configuration file to persist sway reloads (In this example the file is imported in the main sway configuration file with include ~/.config/sway/config.d/*):

swaybg-spread -i ~/some-wallpaper.jpg > ~/.config/sway/config.d/bg.conf 

Use custom location for saving image fragments:

swaybg-spread -i ~/some-wallpaper.jpg -o ~/.theme/fragments > ~/.config/sway/config.d/bg.conf
