Linux with E17

E17 is the latest version from the Enlightenment project, it's a desktop shell and unlike other windows managers such as Gnome, KDE, and Xfce, it doesn't use a "normal" image as background instead it uses an EDJE file so it doesn't support "real" transparency (at least in the current version).

The configuration is very simple, after setting it, you can put it away, and you'll have your status ready.
