Dual 1280×1024 Ubuntu Wallpaper
I’m a huge fan of the default background for Ubuntu 13.10, but my current setup involves two 1280×1024 monitors and setting the same background for both doesn’t look quite how I’d like. With that in mind, I created a 2560×1024 image with a similar color palette and style in GIMP, and decided to share it in case anyone else wants that sort of thing.
If the resolution isn’t right for your setup, it’s reasonably simple to make something similar by using a color picker on the original wallpaper, playing with the “Lighting Effects” plugin under Filters > Light and Shadow in GIMP, and finishing off with a bit paintbrush touch-up in layers with very low opacity.
