If we are about to finish a frame, but a redraw is pending and we let the compositor redraw, we need to check for errors. If the redraw fails and the backend cannot schedule a page-flip, we need to finish the frame, anyway. All backends except DRM use a timer to schedule frames. Hence, they cannot fail. But for DRM, we need to be able to handle drmModePageFlip() failures in case access got revoked. This fixes a bug where logind+drm caused keyboard input to be missed as we didn't reenable it after a failed page-flip during deactivation.
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.
