Want to change the wallpaper on your CDE desktop? It's easy:
There's just one catch - and it's a big one. The backdrop style manager chokes on large image files. By "large", I mean "bigger than about 113 by 88 pixels - the size of the SolarisLogo.pm image that's one of the default backdrop images.
Of course, I started out by trying this with an 8-meg image file; the poor little style manager utility chokes to death trying to start up with that image in the directory. I think it's trying to generate a thumbnail view, or something.
I created a new XPM image (72x72 pixels), copied it into the directory, set permissions to 444 and ownership to root:bin, and it works like a charm.
NOTE: The backdrop image is tiled, period. I don't see a way to center an image and only display it once.
Now, to see what the effective limit on image size really is..
