Unity vs GNOME: Understanding the Difference

Ubuntu 18

In the world of Linux, the desktop environment plays a crucial role in defining the user’s experience. Among the numerous desktop environments available, Unity and GNOME stand out due to their widespread usage, particularly in Ubuntu. This article aims to delve into the differences between these two popular desktop environments, helping you understand their unique features, similarities, and distinctions.

Quick Answer

Unity and GNOME are two popular desktop environments used in Linux, particularly in Ubuntu. Unity is the default desktop environment for Ubuntu and is known for its unique top panel and left-side launcher. GNOME, on the other hand, is a desktop environment project that supports the GNOME Shell, which features a top bar and dash for navigation. The key differences between Unity and GNOME lie in their window managers, notification systems, interfaces, and integration with third-party services. Ultimately, the choice between Unity and GNOME comes down to personal preference.

Unity: An Overview

Unity is the default desktop environment for Ubuntu, developed by the Ayatana Project. It is characterized by its unique top panel and left-side launcher or dock, providing a distinctive user interface.

Unity’s Architecture

Unity uses Compiz as its window manager, a system that controls the appearance of windows. It also utilizes NotifyOSD for notifications, a tool that provides passive unclickable pop-up notifications.

Unity’s Aesthetics

Unity’s user interface is designed to be simple and user-friendly. The top panel contains the application menu, system indicators, and the clock. The left-side launcher/dock, often referred to as the Unity launcher, houses the application icons and allows for quick access to frequently used applications.

Unity’s Integration with Third-Party Services

Unity offers integration with third-party services through its Scope and Lens features. Lenses are used to display user-generated unstructured data, while Scopes fetch and display the data.

GNOME: An Overview

GNOME is a desktop environment project that supports the GNOME Shell, the default shell used in GNOME. It is developed by the GNOME Project and is known for its top bar and dash for navigation.

GNOME’s Architecture

GNOME Shell primarily uses Mutter/Clutter as its window manager. Unlike Unity, GNOME Shell uses the libnotify library for notifications.

GNOME’s Aesthetics

The GNOME Shell interface is minimalist, with a focus on reducing clutter and providing a clean, streamlined user experience. The top bar contains the Activities button, clock, and system status area. The dash is a dock that appears on the left side of the screen when you click the Activities button or press the Super (Windows) key.

GNOME’s Evolution

It’s important to note that there are different versions of GNOME. GNOME 2, now obsolete, was forked to become MATE. MATE offers an experience similar to GNOME 2 with updated features. GNOME 3, the current version, provides a modern, sleek interface and is what you see when you install Ubuntu GNOME.

Unity vs GNOME: The Key Differences

While both Unity and GNOME offer unique user experiences, they have some key differences:

  1. Window Manager: Unity uses Compiz, while GNOME uses Mutter/Clutter.
  2. Notifications: Unity uses NotifyOSD, while GNOME uses libnotify.
  3. Interface: Unity has a top panel and left-side launcher/dock, while GNOME has a top bar and dash.
  4. Integration with Third-Party Services: Unity provides integration with third-party services through its Scope and Lens features, while GNOME does not have a similar feature.
