Meet Nova OS, Cuba’s Linux-kernel based operating system, built by students of University of Computer Sciences.
The operating system is called Nova OS and the latest available version is 4.0, released March 22, 2013, which is based on Canonical’s Ubuntu 12.04 LTS (Precise Pangolin) and built around the GNOME 3.4 desktop environment.
Yes, that means Nova OS does not use Ubuntu’s Unity user interface, providing users with a traditional layout comprising two panels, using GNOME’s GNOME-Shell interface, but with a custom design.
At the moment, Nova OS 4.0 is distributed in three editions, Escritorio, Ligero, and Servidor. The Escritorio edition is the main one, also known as the Desktop CD, which provides users with a complete GNOME-based desktop environment.
