LXQt offers a lightweight yet modern alternative to the heavy GNOME shell, making it an attractive choice for older laptops or users who want fewer resource demands while still enjoying a polished interface. The guide walks readers through updating Fedora first, then installing the entire desktop group with @lxqt-desktop, and optionally adding configuration tools like lxqt-config or panels such as lyx to keep the system lean. After logging out of GNOME, users simply select “LXQt” on the GDM login screen, launch the settings utility to tweak panel placement and auto‑start services, and can even swap in a Qt‑friendly terminal or XFCE file manager for a cohesive look. The article also cautions about common pitfalls—such as missing session files or broken panels after kernel updates—and recommends cleaning up by removing GNOME packages once the new environment is stable, freeing disk space and reducing background load.

How to Install LXQt on Fedora: A Quick‑and‑Dirty Guide

If you’re tired of the heavyweight GNOME shell and want a lightweight desktop that still feels modern, LXQt is your go‑to. Below is a straight‑forward walk‑through for installing it on Fedora 38 (or any recent release). No fluff, just the steps I’ve used in my own setup.

Why LXQt on Fedora?

LXQt packs a punch: a clean interface, low resource usage, and a handful of tweakable panels. On a mid‑range laptop or an older desktop that’s been stuck in GNOME forever, switching to LXQt can feel like breathing fresh air. I’ve seen users complain about lag after installing new drivers—switching to LXQt often solves that without losing any functionality.

1. Update Your System First

sudo dnf upgrade --refresh

Fedora’s packages are tightly coupled; installing a new desktop on an out‑of‑date system can break dependencies or leave orphaned packages. A full refresh guarantees the base libraries you need for LXQt.

2. Install the Core Packages

sudo dnf install @lxqt-desktop

The @lxqt-desktop group bundles everything: the session manager, panels, file explorer (pcmanfm‑qt), and the necessary Qt libraries. It keeps your install lean; you won’t have a half‑baked desktop that misses critical components.

3. Add Optional Extras

sudo dnf install lxqt-config lxqt-configuration lyx

lxqt-config gives you the LXQt settings utility, while lyx is the classic lightweight Xfce‑style panel that many users love. If you’re on a machine with an old GPU or just want to keep things minimal, skip this and add them later.

4. Switch from GNOME (if you’re already in it)

• Log out of your current session.
• On the login screen, click the gear icon next to “Login” and select LXQt from the list.
• Enter your password and hit Enter.

Fedora’s display manager (GDM) keeps track of installed sessions. Selecting LXQt here tells GDM to start that environment instead of GNOME.

5. Fine‑Tune with lxqt-config

Once logged in, open LXQt Settings from the menu or run:

lxqt-config

• Adjust panel placement.
• Add a system tray.
• Enable “Auto‑start on boot” for anything you need (e.g., network manager, clipboard manager).

LXQt is modular; customizing it lets you mimic your old desktop habits while keeping the lightweight vibe.

6. Optional: Install Extra Apps

If you want a terminal that looks like it belongs in LXQt:

sudo dnf install qterminal

For a file manager with icon view, install Thunar (XFCE):

sudo dnf install thunar

Fedora’s default terminal is GNOME Terminal, which feels out of place in a Qt desktop. qterminal and thunar blend nicely.

7. Clean Up

After installation, you can remove the old GNOME packages if you’re sure you won’t need them:

sudo dnf groupremove "GNOME Desktop"

Freeing up disk space and reducing background services that might hog resources.

Common Pitfalls

• Missing gnome-session: Some users report “session not found” errors. Installing @lxqt-desktop fixes this; the group pulls in the session files automatically.
• No panel icons: If panels appear empty, launch lxqt-config and add a “panel applet” manually. I’ve seen this happen after a kernel upgrade that broke Qt support.

Hope that helps you get LXQt running smoothly on Fedora! Feel free to tweak it until it feels like home—after all, the point of a lightweight desktop is exactly that: minimal overhead, maximum freedom.
