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 is enabled by default in the GNOME Desktop. You can choose to run GNOME in X11 by choosing the Gnome on xorg option in the session chooser on the login screen. Currently KDE still uses X11 and although there is a plasma-wayland session available, it is not considered stable or bugfree at this time.

Feststellen, ob Wayland verwendet wird

Ein Weg, um festzustellen ob Wayland verwendet wird, ist das Anzeigen der Variable $WAYLAND_DISPLAY. Um dies zu tun, dies eingeben:


Wenn du kein Wayland verwendest, ist diese Variable leer. Du kannst auch loginctl verwenden, um die Art der Sitzung anzuzeigen:

$ loginctl show-session <YOUR_SESSION_NUMBER> -p Type

To determine your session number, simply typing loginctl should provide your session details.

There is also a legacy X11 server provided with Wayland for compatibility purposes. To determine what applications are running in this mode, you can run the following command:

$ 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”.
