In Fedora 19, GTK+ has been built with Wayland and X11 support, so all you need to try it is a Wayland compositor.
Weston, the reference Wayland compositor, is available in the weston package.
To install it
$ sudo yum install weston
To run weston as an X client.
$ weston &
“&” will place running process in background, so you can still use that terminal.
Then to launch some GTK Apps inside, you first need to set the “GDK_BACKEND” environment to “Wayland”.
And export it, so you can actually use it
$ export GDK_BACKEND
Then you can try run GTK Apps
For using Clutter Wayland backend which is also enabled by default in Fedora 19 Clutter Package you can:
$ export GDK_BACKEND=wayland CLUTTER_BACKEND=wayland
