The function drm_output_start_repaint_loop() unconditionally issues a page flip, even if the crtc for that output has not been enabled yet. That causes the page flip to fail, and drm_output_repaint() is never called. Solve this by bypassing the initial page flip if the output needs a mode set. This has the caveat of affecting latency predictability for that first frame and when a "driver" mode fullscreen surface causes a mode set. However, on both cases the mode set would take an unpredictable amount of time anyway. https://bugs.freedesktop.org/show_bug.cgi?id=63812 https://bugs.freedesktop.org/show_bug.cgi?id=64183
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
