The Wayland Protocol

Wayland is a display server protocol which was (at the time of writing) introduced as the default 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 protocol 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 está habilitado por defecto en el Escritorio GNOME. Puede elegir ejecutar GNOME en X11 eligiendo la opción Gnome sobre xorg en el seleccionador de sesión de la pantalla de acceso. Actualmente KDE usa todavía X11 y aunque hay una sesión plasma-wayland disponible no se considera estable y libre de errores en este momento.

Determinando 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 type of session is running:

$ loginctl show-session <YOUR_SESSION_NUMBER> -p Type

Para determinar su número de sesión, tecleando simplemente loginctl se le suministrarán los detalles de su sesión.

También se proporciona un servidor X11 heredado con Wayland para propósitos de compatibilidad. Para determinar qué aplicaciones están corriendo en este modo, debe ejecutar el siguiente comando:

$ xlsclients

There is also the lg (looking glass) tool in GNOME that will allow you to determine which protocol a specific 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”.
