Hello Linux Geeksters. As you may know, Unity is the default desktop environment of Ubuntu, the latest version available being Unity 7.2, based on GTK +3.10, which is present on Ubuntu 14.04 Trusty Tahr.
In this article I will show you how to install Unity 7.2 on Arch Linux. Unity on Arch Linux has the same functionalities as it has on Ubuntu, all elements (AppMenu, applets, etc) working properly.
Because it is available via repository, installing Unity on Arch Linux is easy. All you have to do is add the repository and install the unity package.
To add the repository, you have to open the /etc/pacman.conf file in a text editor, with sudo:
$ sudo vim /etc/pacman.conf
And paste the below text:
SigLevel = Optional TrustAll
Server = http://mooos.org/repos/moo/$arch
Now, install Unity, via pacman:
$ sudo pacman -S unity
Next, restart your computer to start the Ubuntu session:
$ sudo reboot
