As I have just said in the previous article, OpenSUSE 12.3 has just been released today. It can be used with Gnome, KDE, XFCE or E17.
For Gnome, KDE and XFCE, you have some special Live CDs/DVDs that help you with the installation, but for E17 you don’t.
So, if you want to use E17 on your new OpenSUSE 12.3, just download and install an OpenSUSE 12.3 version, and install Enlightenment 17 with zypper, by the command line interface:
$ sudo zypper in e17
Now reboot the system and choose E17 from the graphical menu.
