How to install LXDE GUI in Debian 11 Bullseye

The LXDE (Lightweight X11 Desktop Environment) is a program that aims to create a lightweight and fast desktop environment. This software is a meta-package that relies on the LXDE’s core and recommended components such as lxde-core, lxappearance, lxinput, lxsession-edit, gpicview, mousepad, lxterminal, galculator, lxrandr, and xarchiver. LXDE is optimized for devices with limited resources, including older resource-constrained PCs, newer netbooks, and other compact computers.

This tutorial guide will illustrate how to install LXDE on an existing Debian 11 Bullseye installation. Therefore, to learn more, keep reading this article guide.

Installing LXDE GUI in Debian 11 Bullseye

To install LXDE on Debian 11, we will use the apt command.

Note: You can also use the apt-get or aptitude command:

First, update the system with the following command:

sudo apt update
apt update resources
Apt update resources

After that, you can install LXDE using this command:

sudo apt install lxde task-lxde-desktop -y
install lxde
Install LXDE

The above command will install the necessary packages and dependencies to run the GUI.

You will be prompted to configure Lightdm throughout the installation process; hit OK when prompted, as seen below.

Select lightdm and hit ENTER on the following screen, as seen below.

Note: If the preceding setting didn’t prompt you, or if you wish to switch to Lightdm once LXDE is installed, execute the following command to bring up the setup panel.

sudo dpkg-reconfigure gdm3

Press OK on the setup screen.

click ok
Click OK

Select Lightdm and hit ENTER on the following screen.

configure lightdm
Configure lightdm

Note: If you cannot still configure the installed LXDE desktop, skip and switch the user and choose LXDE.

Log out or switch users after installing LXDE and selecting Lightdm to effect changes made on your Debian 11 OS.

Note: If you have a problem with xfce4-terminal, which is the default terminal emulator for LXDE, you can install another terminal like this:

sudo apt-get install lxterminal
install lxterminal
Install lxterminal

After that, you have to configure LXDE to run at startup. To do this, we use the following command:

sudo dpkg-reconfigure lxsession
reconfigure lxsession
Reconfigure Lxsession

After that, reboot your PC. You should note a new icon on your desktop called “LXDE.” When you click on it, it will show the login screen. Now you can sign in and enjoy using LXDE.

If you want to change the default terminal emulator, you can use the following command:

sudo dpkg-reconfigure xfce4-terminal

or

sudo update-alternatives --config x-terminal-emulator
change default terminal
Change default terminal

How to install LXDE during Debian installation

The Debian installation process has a very basic and easy-to-use installer. For example, the following instructions will guide you through installing LXDE on your new Debian machine. This section covers how to install LXDE during the Debian installation process if you don’t already have Debian installed. The installation procedure is nearly identical to Gnome’s; the main variation is in the package selection stage. So let’s get started.

Insert your media installer (DVD, USB) and start it up.

Now click on “Install” followed by “Graphical install.” The installer window will now appear:

graphical install
Graphical install

Click the “Continue” button, and you will be presented with a menu of different language options for the installation process. Select your preferred language, choose your location (the country where you live), and then click “Continue” to proceed. Once this data has been entered, you should see a screen like the one shown below:

select language
Select Language

Select your desired keyboard layout (for example, United States) and press “Continue” to proceed with the installation process.

Note: On the next screen, you can choose whether or not you want to run an update of your software packages before continuing with the installation process.

Depending on your computer specifications, the installer will load the required components, which might take a few seconds to many minutes.

The next step is to choose your system hostname, which is the name that displays after your username, such as fosslinux@hostname. The hostname might be the computer name if you’re using Windows. This is an entirely random decision. Then hit the Continue button.

choose hostname
Choose hostname

The following form contains another random field that asks for your domain name; if you like, you can leave it blank, then hit Continue.

The root user must now be given a password. If you’re a Windows user, the root user is equivalent to the Administrator user. Continue after filling in the password.

Another arbitrary field requires you to provide your user’s true name; you can type whatever name you like (This is not the username). Then hit the Continue button.

input user full name
Input the user’s full name

Now type the non-privileged username into the empty username field and click Continue.

setup username

Press Continue after defining a new passphrase for the non-privileged user you created in the previous step.

Choose your time zone; this is necessary for your computer clock to function appropriately; once you’ve chosen a time zone, further options will appear; then hit the Continue button.

Now you must allocate disk space or partitions for the new Debian installation. It is advised that new users take advantage of the available free space. Use the “Guided – use the entire disk” if you have no substantial knowledge about partitioning and don’t want to tamper with any of your hard drive partitions. You may proceed if you are comfortable with Linux partitions.

Select the disk device that you want Debian 11 OS to be installed; if you have a unique disk, that’s OK; if not, choose the proper disk and click Continue.

Now you must decide where you want your files to be installed. In this scenario, we’ll install all files in a single partition, which is the preferred choice for new users; if you’re an expert user, you can partition your disk as you wish. Continue when you’ve made your selections.

choose partitioning scheme

Select “Finish partitioning and write changes to disk,” then hit Continue.

The installer will probe whether you want to install up-to-date packages from a mirror; you may click “Yes” and then choose a mirror, or you can select “No” and update packages later using the apt update command. Choose your preferred choice and hit Continue.

choose debian archive mirror
Choose Debian archive mirror

The installation of packages will begin, and you will be needed to engage with the package selection at this time.

When prompted, “Would you want to participate in the package usage survey?” Select the desired option and click Continue.
