Title: Using GTK with Wayland Slug: gtk-wayland 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.
