ubuntu 22.04 wayland confirm terminel

$XDG_SESSION_TYPE

The default display manager for the GNOME desktop environment is GDM3. Therefore, we will edit the /etc/gdm3/custom.conf file to either disable or enable Wayland. Open a command line terminal and use nano or your favorite text editor to open this file with root permissions.
```
$ sudo nano /etc/gdm3/custom.conf
```
Within this file, look for the line that says #WaylandEnable=false. You can uncomment this line and either set it to true or false, depending on whether you want Wayland enabled or not.
Enable Wayland:
```
WaylandEnable=true
```
Or disable Wayland:
```
WaylandEnable=false
```
