#### Using GTK with Wayland [src]

The GDK Wayland backend provides support for running GTK applications under a Wayland compositor. To run your application in this way, select the Wayland backend by setting `GDK_BACKEND=wayland`.

On UNIX, the Wayland backend is enabled by default, so you don’t need to do anything special when compiling it, and everything should “just work.”

## Wayland-specific environment variables

### WAYLAND_DISPLAY

Specifies the name of the Wayland display to use. Typically, wayland-0 or wayland-1.

### XDG_RUNTIME_DIR

Used to locate the Wayland socket to use.
