Press Y and hit enter when asked if you want to continue.

This ensures you are working with the most recent software updates.

Next, install the tasksel manager utility:

sudo apt-get install tasksel

Now it is time to install a desktop environment.


Select a Display Manager


A display manager is an application that starts the display server, launches the desktop, and manages user authentication. The default GDM3 (used with KDE-Plasma) is a resource-intensive display manager. If you need to conserve system resources, consider a lighter display manager, like SDDMSLiM, or LightDM.

By default, only one display manager can manage a server. They can run simultaneously only if configured to manage different servers. This article assumes that you will be using a single default display manager.

To install a specific display manager, use the apt-get package manager:

To install SLiM:

sudo apt-get install slim

To install LightDM:

sudo apt-get install lightdm

The SDDM display manager can be installed from the tasksel menu during the KDE installation.

Choose a GUI for Your Server


GNOME is the default GUI for most Ubuntu installations and is (loosely) based on the Apple ecosystem.

KDE is another popular GUI, (loosely) based on the Microsoft ecosystem. If you want to have the look and feel of a regular Ubuntu system, choose one of these desktop environments.



To install GNOME, start by launching tasksel:


A colorful interface will launch. Use the arrow key to scroll down the list and find Ubuntu desktop.

Use the Space key to select it, press Tab to select OK at the bottom, then press Enter.

The system will install the software and reboot, giving you a graphical login screen generated by your default display manager. In our case, it’s SLiM.

Enter your login credentials. Use F1 to switch between GUIs if you have multiple interfaces installed.

Below is a typical GNOME UI environment.

KDE Plasma


To install KDE Plasma, use the following Linux command:

sudo apt-get install kde-plasma-desktop

You may be prompted during the installation to select a default display manager. Use the arrow keys to make a selection, then press Enter.

Launch KDE Plasma with the command:

sudo service display_manager start

Instead of display_manager, type the name of the display manager you have installed (e.g., SLiM, lightDM, SDDM). Enter your credentials and log in.

Mate Core Server Desktop


Mate is a popular and lightweight graphical interface. Install it by executing the following command:

sudo tasksel install ubuntu-mate-core

Wait for tasksel to complete the action. Once complete, launch the desktop interface with the command:

sudo service display_manager start

Instead of display_manager, type the name of the display manager you have installed (e.g., SLiM, lightDM, SDDM). You’ll be prompted to log in.

To exit the GUI, open the command line and enter:

sudo service display_manager stop


Note: You may need to press Ctrl-Alt-F1 to get back to the server’s command line interface. Also note, this process automatically installs and uses the lightdm display manager.

Lubuntu Core Server Desktop


Lubuntu is a very lightweight GUI. Use this application if you need a graphical interface, but want to minimize the impact on system memory and processor.

To install Lubuntu, enter the following:

sudo tasksel install lubuntu-core

Alternately, you can install from the tasksel menu with the command:


Use the arrow keys to highlight the Lubuntu GUI you want to use. Press the space bar to select, then Tab to the OK button and press Enter.

Launch the GUI with:

sudo service display_manager start

Exit the GUI by opening a terminal window and entering the following:

sudo service display_manager stop

Xubuntu Server Core Desktop


Xubuntu is a derivative of Ubuntu that uses the Xfce desktop environment.

Install Xubuntu by entering the following:

sudo tasksel install xubuntu-core

Launch it by entering:

sudo service display_manager start

Xfce Desktop


The Xfce desktop environment can be used by itself. It’s designed to be responsive, lightweight and user-friendly.

Install Xfce with the following:

sudo apt-get install xfce4 slim

Launch Xfce by entering:

sudo service slim start

Xfce desktop environment


Switching Between GUIs


If you have several GUIs installed you can select which one to use. Once you start your display manager, you will be prompted to log in. However, that screen also allows you to pick which GUI you want to enable.

The image above represents SLiM’s login screen. Switch between GUIs by pressing F1. The interface will toggle between sessions (or GUIs). Log in once you toggle to the GUI of your choice.
