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 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.
Satu cara untuk menentukan apakah Anda sedang menjalankan dalam Wayland, adalah dengan memeriksa nilai dari variabel $WAYLAND_DISPLAY. Untuk melakukan ini ketikkan:
$ 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 <NOMOR_SESI_ANDA> -p Type
Untuk menentukan nomor sesi Anda, sekadar mengetik
loginctl mestinya memberikan rincian sesi Anda.
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:
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”.
