Hi, first, let's put this on the proper mailing list for everyone's benefit. You create a wl_surface with the wl_compositor.create_surface request. That is all. Only the wl_compositor is required, nothing else. Of course, such a wl_surface will be useless until you do two more things: - give it a role - give it content (create a wl_buffer, fill it with data, and wl_surface.damage+attach+commit it) Only after these you may see something on the screen. Refer to http://wayland.freedesktop.org/docs/html/apa.html#protocol-spec-wl_surface for how to do things after you created a wl_surface. There is no difference in which you create first, a wl_surface or a wl_buffer. There are different kinds of wl_buffers created in different ways, because of different ways to associate data with them: drawing with the CPU, rendering with the GPU, hardware-decoded video... Thanks, pq
