Pantheon desktop environment
It can be installed on Ubuntu if you want to get the elementary OS like look and feel without changing the OS. In this example we are installing it on Ubuntu 13.04
Add the elementary ppa to ubuntuThe elementary ppa provides all the necessary packages to get the Pantheon desktop environment. Add it to ubuntu repositories like this. Also make sure to update.
# sudo apt-add-repository -y ppa:elementary-os/daily # sudo apt-get update
Now install the elementary desktop
# sudo apt-get install elementary-desktop
Thats it, now log out and on the login page, the Pantheon desktop should be visible in the list of desktop environments.
Fix the missing wallpaper issueThere seems to be a bug in the way Pantheon is installed which causes the wallpaper to go missing and a white desktop background displayed instead. To fix this run the following command in your terminal
# gsettings set org.gnome.settings-daemon.plugins.background active true
Again logout and login back, and the wallpaper should display fine.
Install elementary tweaksThe next useful thing to install along with pantheon desktop is the elementary tweaks extension, which allows to tweak the pantheon desktop in some ways.
# sudo apt-add-repository ppa:versable/elementary-update # sudo apt-get update
$ sudo apt-get install elementary-tweaks
Elementary tweaks will appear as an additional icon in System Settings dialog. Over there you can configure the plank, slingshot etc.
So have fun with your Pantheon desktop and njoy!!
