My Manjaro Linux & my qemu objects Plasma UI which is the latest instead of X11 X Windowing System 😜

To switch your Manjaro KDE Plasma session back to X11, you need to change your session setting at the login screen or through your SDDM settings. [1, 2]

Here are the exact steps to fix it:

Method 1: Change it at the Login Screen

1. Log out of your current Plasma session.
2. In the bottom-left corner of the login screen, click on the Session dropdown menu.
3. Select Plasma (X11) (or Plasma (Xorg)).
4. Enter your password and log in. Your system will now remember this setting for future logins. [1, 2, 4, 5]

Method 2: Change it in System Settings (If Auto-Login is enabled)

If your system automatically logs you in and skips the login screen, you must change the default session in your settings: [1, 2]

1. Open your application launcher and search for System Settings.
2. Navigate to Colors & Themes → Login Screen (SDDM).
3. At the top of the window, click on the Behavior tab.
4. Look for the Automatically log in section.
5. In the With session dropdown, change it from Plasma (Wayland) to Plasma (X11).
6. Click Apply in the bottom right and reboot your computer. [1, 2, 4]

Note: If the X11 Option is Missing

Newer Manjaro ISOs sometimes install without the X11 package by default. If you don't see the option to switch, you can install it via the terminal by running:
sudo pacman -S plasma-x11-session
Once it installs, restart your system and the Plasma (X11) option will appear. [, 2]

If you can tell me which specific QEMU or virtualization issue you are experiencing (e.g., display scaling, mouse cursor capture, or performance), I can provide more targeted steps to resolve it.
