Using Terminal
- The default display manager is GDM3. So, we'll need to edit the custom.conf file.
Open a command liner terminal using any text editor (We are using vi) and open this file with root permission.
sudo vi /etc/gdm3/custom.conf
2. Look for the line that says "WaylandEnable=true". Change it to "WaylandEnable=false".
3. Now restart the GDM3 or reboot your desktop.
$ sudo systemctl restart gdm3
4. To check the current version, run this code in the Terminal:
echo $XDG_SESSION_TYPE
Using GUI
You can use GUI to switch display servers easily.
- Disable Automatic Login. Go to Settings>Users and turn off the toggle button.

4. You can check the version from Settings>About and check the "Windowing System". It'll show X11 if it's Xorg.
