To do so, we need to add a small command to your
.xsessionfile. First install the program feh with
yum install feh -yif it's not already installed. Feh is also a decent program for viewing images too, which is why i'm using it.
To have feh draw your desktop background, just add the following command to your .xsession file, before the line for xmonad (or which ever window manager you choose):
feh --bg-scale /path/to/wallpaper
It's really not more complicated than that.
Somethings you might want to explore, if you like that sort of thing is that there are a number of programs that can all draw to the root window. It's possible to use them to draw pictures, tile multiple pictures together, create a slideshow, or even draw video or goofy animations that follow the cursor. If you find something cool, be sure to leave a comment or blog it too.
