The Wayland Display Server

Wayland is a display server which was (at the time of writing) introduced as the default display server in GNOME. It is said that Wayland will eventually replace X11 as the default display server on Linux and many distributions have begun implementation of Wayland. Wayland is a more modern display server and has a smaller code base currently. Wayland is still under development, and there are still applications and behaviours that don't work as expected, you may find that some applications have not been updated to work properly in Wayland and currently the only way these applications will run is using Xorg instead of Wayland. This includes some legacy system applications and games.
Wayland in Fedora

Wayland está habilitado de modo predeterminado en el Escritorio GNOME. Puede elegir correr GNOME en X11 eligiendo la opción Gnome sobre xorg en el selector de sesión de la pantalla de acceso. Actualmente KDE utiliza todavía X11 y a pesar de que hay una sesión plasma-wayland disponible, no se considera aún estable y libre errores.

Determinar si está usando Wayland

Una manera de determinar si está corriendo en Wayland es comprobar el valor de la variable $WAYLAND_DISPLAY. Para hacer esto teclee:

$ echo $WAYLAND_DISPLAY
wayland-0

If you are not running under Wayland the variable will not contain any values. You can also use loginctl to show you what tpe of session is running:

$ loginctl show-session <YOUR_SESSION_NUMBER> -p Type

Para determinar su número de sesión, teclear simplemente loginctl debería proporcionarle detalles de se sesión.

También se proporciona un servidor X11 heredado con Wayland por motivos de compatibilidad.. Para determinar que aplicación está corriendo de este modo, puede ejecutar el siguiente comando:

$ xlsclients

There is also the lg (looking glass) tool in GNOME that will allow you to determine what display server a window is using. To do this, you run the application by typing lg in the run dialog or at the command line, select “Windows” in the upper right corner of the tool, and click on the application name (or open window) you want to know about. If the window is running in wayland it will say “MetaWindowWayland” and if it is running in X11 it will say “MetaWindowX11”.
