Installing E17 on Ubuntu
Installing the E17 Enlightenment desktop on Ubuntu 12.04 is very easy, just type this command in a terminal emulator window.
sudo apt-get install e17
And then all the packages will be installed. You will need to convert old themes into the new format for them to work with the newer Enlightenment release. The desktop is a bit flaky with the tendency to segfault sometimes, but you just click recover and the desktop comes back to life.
