The Wayland Display Server
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.
Ein Weg, um festzustellen ob Wayland verwendet wird, ist das Anzeigen der Variable $WAYLAND_DISPLAY. Um dies zu tun, dies eingeben:
$ echo WAYLAND_DISPLAY
wayland-0
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”.
