How to Install LXQt on Ubuntu 24.04, 22.04, or 20.04

If you’re looking for a lightweight yet feature-rich desktop environment for your Ubuntu system, LXQt could be an excellent choice. This guide will focus on installing LXQt on Ubuntu 24.04 Noble Numbat, Ubuntu 22.04 Jammy Jellyfish, or Ubuntu 20.04 Focal Fossa. LXQt offers a different experience from the default GNOME desktop environment.

Why Consider LXQt on Ubuntu?

  • Performance: LXQt is designed to be lightweight, making it suitable for systems with limited resources. Despite its low memory footprint, it offers a smooth user experience.
  • Customization: LXQt features a modular design, allowing users to add plugins and tailor the desktop to their liking.
  • User-Friendly Interface: LXQt provides a straightforward, classic interface, which may appeal to those who prefer simplicity over the modern look of GNOME.
  • Compatibility: Built on the Qt framework, LXQt works well with all major Linux distributions, making it easy for users who switch between different Linux environments.
  • Functionality: LXQt supports multiple window managers and offers advanced settings to control your desktop environment precisely.

If you’re intrigued by LXQt’s offerings, stay tuned. The upcoming guide will provide step-by-step instructions for installing the alternative desktop method, which works with short-term releases.

Updating Ubuntu System Before LXQt Installation

Starting with a fully updated system and ensuring the latest software and security patches are installed is crucial. This reduces the risk of potential conflicts during the LXQt installation. The following commands are used to achieve this:

sudo apt update
sudo apt upgrade

The first command, sudo apt update, refreshes your system’s package lists, ensuring that Ubuntu is aware of the latest versions of software available. The second command, sudo apt upgrade, will subsequently upgrade all outdated software on your system.

Installing LXQt via APT Command

LXQt is conveniently available in Ubuntu’s repositories, simplifying the installation process. Its lightweight nature ensures that download and installation are considerably faster than other desktop alternatives. Here’s how you install LXQt on your system:

sudo apt install task-lxqt-desktop

In this command, sudo is used for executing the command with root privileges. apt install is the command for installing software, and task-lxqt-desktop is the package name for the LXQt desktop environment.

For minimal server installations, LXQt can be installed with the following command:

sudo apt install lxqt

During the installation process, you’ll encounter the “Configuring sddm” screen. SDDM (Simple Desktop Display Manager) is the display manager and login screen that LXQt uses. To continue, press the TAB key to highlight <Ok> and press ENTER.

Rebooting the System

Upon successful installation of LXQt, reboot your system to finalize the changes. Rebooting allows your system to initialize LXQt properly and ensures its proper functioning. Here’s how you can reboot your system using the terminal:

sudo reboot

Accessing LXQt Desktop Environment

Navigating the Login Screen with LXQt

After your system restarts following the LXQt installation, you will encounter your login screen. By default, LXQt should be automatically selected as your desktop environment. If this is not the case, you can manually select LXQt.

To choose LXQt, locate the desktop environment selection option in the top left-hand corner of the login screen. Click on this dropdown and select “LXQt” as your desktop environment. This will replace the default choice of “GNOME (Wayland).”

Understanding the Initial Appearance with LXQt

When you first log in to LXQt, the appearance of your login screen may resemble a Debian interface. This can initially seem confusing, given that you are running Ubuntu. However, there’s no need for concern; this occurrence can be attributed to Ubuntu’s lineage.

Ubuntu is fundamentally built upon Debian; hence, certain aspects of Debian’s aesthetic design can manifest in Ubuntu, particularly when installing alternative desktop environments like LXQt. It’s important to remember that this initial appearance can be customized and adjusted to your liking in subsequent steps, offering a truly tailored desktop experience.

Tips for Managing LXQt with Additional Commands

Switching Default Display Managers with LXQt on Ubuntu

Reverting to GNOME from LXQt starts with resuming the display manager selection screen, similar to what you encountered during the LXQt installation process. This can be achieved by running the following command in your terminal:

sudo dpkg-reconfigure sddm

This command initiates the SDDM display manager’s configuration process, allowing you to select an alternate default option, such as GDM, for GNOME. Please note it is essential to reboot your system whenever you switch display managers or desktop environments to ensure all changes are accurately incorporated.

sudo reboot

Uninstalling LXQt

There might be situations where you decide to uninstall LXQt. Maybe you’re keen on trying out another desktop environment or want to revert to your previous configuration. If you find yourself in this position, you can remove LXQt as follows:

Run the following command in your terminal:

sudo apt-get remove lxqt*

The command will expel LXQt and any associated files from your system, returning your desktop environment to its prior state.

Following the LXQt removal, it’s probable that you’ll need to reinstall the GNOME Desktop Environment. The process of LXQt uninstallation might have led to the removal of some packages that GNOME relies on. Hence, to reinstall GNOME, update your package list and install the ubuntu-gnome-desktop package:

sudo apt update && sudo apt install ubuntu-gnome-desktop

Finally, to ensure all modifications are correctly applied, reboot your system:

sudo reboot

Conclusion

Trying out LXQt on Ubuntu Linux has been a smooth ride. The guide walked through the easy installation and management steps, showing that even beginners can handle it. LXQt stands out for its lightweight and efficient performance, making it perfect for systems that need to stay speedy. Remember to keep the key commands handy for installation, logging in, and removing LXQt if needed. Give it a shot if you’re looking for a simple, fast desktop environment.
