How to install and set up KDE desktop environment on Arch Linux? for this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

I'm sure you installed Arch Linux in accordance with this great guide, which ends with the installation steps for GNOME desktops.

But now, not everyone is a fan of GNOME, and several readers have asked us to show them how to configure the KDE desktop on Arch Linux.

Therefore, I created this guide to demonstrate the steps to properly install and configure the KDE desktop (also known as the KDE Plasma desktop) on Arch Linux. How do I install and set up the KDE desktop environment on Arch Linux?

Remember, KDE does not allow you to log in directly as root. If you have installed Arch Linux and used it as root, you should create a new user and give it sudo permission to run commands as root.

If you only minimize the installation of Arch Linux, then you may be logged in as a TTY terminal. If you are using another desktop environment, the steps are the same.

Let's get started!

Step 1: create a sudo user (if you only have a root user)

You can use the useradd command to create a new user. The user name I created is dimitrios (this is my first name). You can use something that matches your name.

The option-m creates a home directory for the newly created user.

Useradd-m dimitrios

You should also set a password for this user. Use this command:

Passwd dimitrios

Now that you have created the user, give it sudo permission. First, install sudo and a command-line text editor like nano.

Pacman-S sudo nano

The configuration file for sudo is / etc/sudoers. The file should be edited using visudo, which locks the sudoers file, saves the edits to a temporary file, and checks the syntax of the file before copying it to / etc/sudoers.

To use nano as the visudo editor, set up:

EDITOR=nano visudo

Add the following line as in my example, then save and exit.

Dimitrios ALL= (ALL) ALL

Save your changes and exit the editor. You now have a sudo user on Arch Linux.

Step 2: install the KDE Plasma Desktop

To run the KDE desktop, you need the following software packages.

Xorg group

KDE Plasma desktop environment

Session of Wayland KDE Plasma

The KDE application group (including KDE-specific applications: Dolphin Manager and other useful applications).

You can install the above section with the following command.

Pacman-S xorg plasma plasma-wayland-session kde-applications

After installation, enable the display Manager and Network Manager services.

Systemctl enable sddm.servicesystemctl enable NetworkManager.service

It's almost done. Shut down your system.

Shutdown now

Power on the system again and you should see the login screen for KDE. Do you remember the password set for your sudo users? Use it to log in.

Next?

You may want to explore the basic pacman commands, learn about the Arch user repository, and learn about the AUR assistant.

This is the answer to the question about how to install and set up the KDE desktop environment on Arch Linux. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
