Wayland is the new display server protocol used by modern Linux installations. It replaces the old X11 protocol. It’s hipping on Ubuntu 22.04 by default.
To check: open a terminal, and echo the `XDG_SESSION_TYPE` variable.
echo $XDG_SESSION_TYPE
It will output `wayland` or `x11`.
You can still try x11 if you like by selecting that option on login.
