Set Wallpapers for Dual-Head Monitor Setup
This script is intended for people who use a dual-head monitor setup on a Linux computer running Gnome who want to set up different wallpapers. Gnome has no built-in way of doing this, so I wrote a script to do it.
Note: I only tested this in the setup from the example below. It should work for other setups, as long as the first screen is at the left or the top.
Although it should be run from the command line, it uses GTK+ dialogs for file selection. Here’s the syntax:
$ set-wallpapers-dualhead (first screen size) (second screen size) (horizontal | vertical)
For example, if you have two heads, one 1440x900 and one 1280x1024, and they are positioned horizontally (i.e. left-to-right), you’d run:
$ set-wallpapers-dualhead 1440x900 1280x1024 horizontal
Two file selection dialogs will appear, one for each wallpaper. Then, the script will scale them to fit your monitors, combine them into one image file, and set that file as your wallpaper.
