Overview

Let us take a look at the Ubuntu Desktop Environment. Once the user logins in to the Ubuntu machine, the Desktop screen will be displayed to the user. Let’s understand important features of the Ubuntu Desktop Environment.

Ubuntu Login Screen

Once you start the Ubuntu machine, the login screen will be displayed. We need to choose the username and enter the correct password to login to the Ubuntu machine. After successful login Ubuntu desktop will be displayed.

Login screen also displays a menu bar. The menu bar allows us to change the volume control, keyboard and accessibility settings on the machine. We can see these controls on the top right corner of the login screen.

Ubuntu Desktop Environment

The default graphical environment of Ubuntu 20.xx is GNOME. GNOME is an acronym and stands for

GNU Network Object Model Environment.

Menu bar

Like on Login screen, the menu bar is displayed on the top of the Desktop screen. Most of the indicators are displayed on the top right corner area. Some indicators like volume control, network indicator, battery charging indicator etc.

Dock

The Dock is like Taskbar on Windows. By default the Dock is on the left side of the Desktop Screen. Some popular applications are added to the Dock by default. Applications like

• Mozilla Firefox browser.
• Thunderbird Email
• Files
• Ubuntu Software
• Help

Running applications show a dot against the icon in the Dock. For example, In the screenshot the Files application, Terminal, Chrome, Eclipse IDE are running on the machine. We can click on the Activities top left link to display them.

Show Applications

Show applications helps us to find applications and files on the Ubuntu machine. The screen will have a search bar to search for the information. There would be two tabs Frequent and All. Frequent tab displays the most frequent used applications on the system.
