Hello all, My most recent itch has been the ability to set backgrounds in a Xinerama-aware way. I've built bacteria as a tiny utility to help me out with that: http://www.dmwit.com/bacteria It doesn't do much: it just creates an image with the right dimensions to be a background for all the Xinerama screens you happen to be running at the moment. It takes a list of input images and centers them sequentially on each screen. It's designed with scripting in mind; for example, the following line in my .xinitrc: display -backdrop -window root `bacteria .cthulhu.gif .background` suffices to center the silly .cthulhu.gif picture on each screen, and works correctly on a variety of machines with different screen counts and sizes. I hope somebody else finds this useful! (And, if you don't find it useful because it doesn't do X, please send me a note saying what X is. Maybe it turns out I wanted X, too, and didn't even realize it. =) Cheers! ~d
