GNOME Tutorial
Introduction
GNOME (GNU Network Object Model Environment) is a free and open-source desktop environment for Unix-like operating systems. It is part of the GNU Project and is known for its simplicity, ease of use, and modern look. In this tutorial, we will cover the basics of GNOME, how to install it, and how to use its various features.
Installation
Installing GNOME can vary depending on your Linux distribution. Below are the steps for some popular distributions:
On Ubuntu
Open a terminal and run the following command:
sudo apt install gnome-shell
To set GNOME as your default desktop environment, run:
sudo dpkg-reconfigure gdm3
On Fedora
Open a terminal and run the following command:
sudo dnf install @gnome-desktop
Set GNOME as your default desktop environment by enabling GDM:
sudo systemctl enable gdm
Getting Started with GNOME
Once you have installed GNOME and set it as your default desktop environment, you can log out and select GNOME from the session menu on the login screen. After logging in, you will be greeted with the GNOME desktop.
Overview
The GNOME desktop consists of the following key components:
- Top Bar: This is located at the top of the screen and provides access to system status, notifications, and the Activities Overview.
- Activities Overview: This is accessed by clicking on the "Activities" button in the top bar or pressing the "Super" key (Windows key). It provides an overview of open windows and allows you to launch applications.
- Dash: The dash is a dock located on the left side of the Activities Overview. It contains shortcuts to frequently used applications and running applications.
Customizing GNOME
GNOME is highly customizable. You can change the look and feel of the desktop environment using the GNOME Tweaks tool. To install GNOME Tweaks, use the following commands:
