Introduction to Ubuntu Unity
Ubuntu Unity can be described as a distribution of Linux based on Ubuntu along with the Unity interface that is the replacement for the GNOME Shell of Ubuntu. On 7 May 2020, the initial publication was 20.04 LTS. It had many working names of Ubuntu Unity Remix and Unubuntu before the first release.
History of Ubuntu Unity
Originally, the Unity interface was integrated by Canonical Limited and initially added as the default interface within the 11.04 version of Ubuntu which was published in April 2011. Ubuntu Unity was integrated as a replacement to the GNOME Shell which substituted the GNOME 2 interface. Canonical had planned for converging the tablet, cellphone, and desktop interfaces into Unity 8 (the project that was dropped in 2017 when Ubuntu shifted to the GNOME 3 desktop rather, ending the development of Unity at the 7th version, the 8th version being incomplete.
In April 2017, the 17.04 version of Ubuntu released the GNOME 3 desktop but it wasn't universally approved by the developers and users of Ubuntu. Several forks were also proposed along with UBPorts taking over the development of Unity 8 for its value as the cellphone interface and re-titling it Lomiri in 2020 February. Canonical provided its approval for the trademark uses for the Unity 7 Ubuntu remix in 2019.
The Foundation of Linux certified Ubuntu team member and developer Rudra B. Saraswat, who is based near India and Bangalore, began Ubuntu Unity. He surveyed users and applied a stock interface of Unity 7 with the Ubuntu backend and the least modifications otherwise. He added a file manager, which is called Nemo, as a replacement to the GNOME files and selected the LightDM X display manager for replacing the GNOME Display Manager of Ubuntu.
Previously, Saraswat had created many other distributions of Linux including Krob Linux (server-focused). Saraswat stated his encouragement to start Ubuntu Unity, "I have used Ubuntu 17.04 back when I was 8 years old and I really loved Unity 7, so when Unity 7 was discontinued by Canonical, I wasn't happy and wanted to bring it back. I created this project to give Unity 7 a new life". In 2020, Saraswat was 10 years old when he initially published Ubuntu Unity. He has represented that his aim is to eventually have a distribution approved as an official "flavor" of Ubuntu.
