Alternative Ubuntu Desktops: KDE Plasma, XFCE, and Wayland vs X11

1. KDE Plasma (Kubuntu)

Features : extremely gorgeous, highly customizable (you can change any part), Windows‑like layout.

Resource usage : recent optimizations make it even more memory‑efficient than GNOME.

Installation : sudo apt install kde-plasma-desktop During installation you will be asked to choose between gdm3 and sddm; select sddm (KDE’s display manager).

2. XFCE (Xubuntu)

Features : lightweight, stable, retro look.

Suitable for : old computers, servers, users seeking extreme responsiveness.

Installation :

sudo apt install xfce4

3. Switching Desktop Environments

After installing a new desktop you do not need to reinstall the OS. Follow these steps:

Log out the current user.

On the login screen, click the gear icon at the bottom right (or next to the username).

Select the desired session (e.g., “Plasma” or “Xfce Session”).

Enter your password and log in.

4. Wayland vs X11

Wayland : next‑generation display protocol, more secure, less screen tearing, smoother touch‑pad gestures; the default on Ubuntu.

X11 (Xorg) : mature protocol with the best compatibility, especially for older graphics cards, screen‑recording software, and remote control.

If you encounter flickering, black screen during recording, or input‑method issues, try switching back to X11.

Everyday desktop use: Wayland is usually smoother.

Remote control / screen recording / old hardware: X11 prioritizes compatibility.

5. Fully Switching the Distribution?

If you find you prefer KDE, you can download Kubuntu for a fresh install; if you prefer XFCE, download Xubuntu . Both are official Ubuntu flavors that ship with the respective desktop preinstalled.

You can also test a live USB for about ten minutes before deciding to switch.
