LXQt’s blend of speed, customization, and modern design makes it a top choice for Debian users. Now, we will demonstrate how to install this alternative desktop environment quickly on your system.

Refreshing Debian System Before LXQt Installation

To start with the LXQt installation, you must ensure your Debian system is current. Keeping your system updated helps in smooth installations by reducing potential software conflicts.

Update your Debian system by running these commands:

sudo apt update
sudo apt upgrade

The sudo apt update command refreshes the package lists, letting the system recognize the newest software versions. The next command, sudo apt upgrade, upgrades any software on your system that’s out of date.

Proceed to install LXQt via Task Command

LXQt, being a lightweight desktop environment, is readily found in Debian’s repositories. This means you can easily and quickly install it compared to desktop environments.

To install LXQt, run:

sudo apt install task-lxqt-desktop

Here, sudo grants necessary permissions, apt install is the command to install software, and task-lxqt-desktop is the specific package for the LXQt desktop environment.

If you’re working with a server-focused Debian installation and want a minimalist setup, you can install LXQt with:

sudo apt install lxqt

During installation, you’ll see the “Configuring sddm” prompt. LXQt uses the Simple Desktop Display Manager (SDDM) as its login screen. To proceed, highlight <Ok> using the TAB key and press ENTER.

Step 3: System Reboot Post LXQt Installation

After successfully installing LXQt, restart your system. This step ensures LXQt initializes appropriately for optimal performance.

Reboot your system by typing:

sudo reboot

After your system restarts, LXQt will be fully operational on your Debian installation.

Accessing LXQt Desktop Environment at System Login

Navigating the Login Interface

After you’ve installed LXQt and restarted your system, you’ll need to log into the LXQt desktop environment. Usually, LXQt automatically becomes your default desktop environment. If it hasn’t, you can choose it manually.

At the login screen, you’ll find a desktop environment selection option. Typically, it’s located in the top left corner. Click on this dropdown menu. From there, choose “LXQt” to set it as your desktop environment. Doing this will override other choices, like “GNOME (Wayland).”

Management Commands for LXQt

Switch Display Manager

If transitioning from LXQt to GNOME, start at the display manager selection. This process involves choosing a default display manager like GDM for GNOME. Initiate this by entering the command:

sudo dpkg-reconfigure sddm

This command kickstarts the reconfiguration for the SDDM display manager and lets you pick an alternate default display manager. Remember to restart your system after changing display managers or desktop environments to ensure your changes take effect. Use this command to restart:

sudo reboot

Remove LXQt From Debian

If you ever want to remove LXQt, maybe try a different desktop environment, or return to your previous setup, use the following command:

sudo apt autoremove '^lxqt' task-lxqt-desktop --purge

This command cleans LXQt and its associated files from your system.

Upon removing LXQt, you might need to reinstall the GNOME Desktop Environment. Some packages essential for GNOME might have been deleted during the LXQt uninstallation. To get GNOME back, first update your package list. Then, install the GNOME desktop environment with:

sudo apt install gnome gdm3 task-gnome-desktop --reinstall

To make sure you’ve fully implemented all changes, restart your system using:

sudo reboot

Closing Thoughts

Throughout this guide, we have explored the intricacies of installing, navigating, and managing the LXQt desktop environment on Debian Linux distributions. This journey provided a comprehensive understanding of the tools and processes needed to tailor your desktop environment experience, from the first login experience with LXQt to transitioning back to GNOME. Now all you need to do is customize and configure your desktop environment to your liking.
