LXQt is a free desktop environment known for being lightweight, fast, and energy-efficient, which can replace the standard default GNOME Desktop on your Ubuntu system, which can be desired by users with low-powered computers and laptops, and netbooks.
LXQt has had a colorful history of merging and then splitting with the LXDE project in 2013 and 2018. However, both projects are of a high standard in sharing similar approaches regarding being more efficient than the major players such as GNOME and KDE.
In the following tutorial, you will learn how to install LXQt on Ubuntu 22.04 LTS Jammy Jellyfish using the command line terminal.

First, make sure the system is up-to-date to avoid any conflicts.
sudo apt update && sudo apt upgrade -y
By default, LXQt comes in Ubuntu’s repositories, making the installation relatively easy. The desktop environment is lightweight, and the download and installation are very quick compared to some available alternatives.
Install LXQt by using the following command.
sudo apt install task-lxqt-desktop -y
Alternatively, for minimal server installations, use the following command.
sudo apt install lxqt -y
During the installation, you will see the “Configuring sddm.”
LXQt is recommended to run on using sddm. To proceed, press the TAB KEY to select <Ok> and hit the ENTER KEY.
Once complete, reboot your system, which can be done by typing the following directly into your terminal.
Switching Default Display Managers
Alternatively, in the future, if you want to change the default display manager back to GDM3 to use GNOME, you can re-run this pop-up using the following command.
sudo dpkg-reconfigure sddm
Make sure to reboot if you are going from LXQt back to GNOME and vice versa in the future.
First Look & Verifying LXQt
Once you have restarted your desktop, you will arrive at your login screen. By default, LXQt will be automatically selected. If not, then at the top-hand left, select “LXQt” instead of the default “GNOME (Wayland).”
Once logged in, you will notice quite a few UI changes besides the apparent color and background changes. The taskbar is now similar to a more traditional desktop theme than GNOME, along with more integrations in the bottom taskbar such as accessing languages, settings, networks, and much more.
LXQt is not designed to be eye candy compared to other alternative desktop environments, hence why it is fast. One thing you will need to do is find some good wallpapers, as, by default, you will get the typical Debian background wallpaper that comes with it.

How to Update LXQt Desktop
Run the standard apt update && upgrade commands for future updates for the desktop environment and any default APT packages or if you want to check manually for updates to see what is happening in your system.
sudo apt update
When updates are available, run the standard upgrade command as you would with any other apt package.
sudo apt upgrade
Comments and Conclusion
In the tutorial, you have learned how to install the LXQt desktop environment on your Ubuntu 22.04 LTS.
Ideally, you can install this package and switch depending on your mood if you have a decent system. If you prefer desktop jumping, it’s worth checking out if the looks appeal to you. If unsure, I would suggest installing a VM first, then on your main machine, unless you are a severe Linux distro how that doesn’t care about re-installing operating systems.
