David Herrmann aedc7732eb logind: delay wakeup until DRM-device is resumed The logind API was designed to allow any kind of devices and any number of devices. It has no idea of "main DRM device" or similar. However, the weston DRM backend was designed with a single DRM device as master. Therefore, we wake it up unconditionally on session-wakeup. But this may fail with logind as a session may be awake, but not all devices have been resumed, yet. Therefore, we change the weston-logind backend to deal with this case correctly. Instead of waking up the compositor on session-wakeup, we wait for the main DRM device to wake up. Once we get the event, we notify the compositor. For sleep, we reverse this logic. On any of the following events we tell the compositor to go to sleep: - Session gets inactive - DRM device gets inactive - DRM device is removed This guarantees, that weston is only active if both, the session and the main DRM device are awake/active. Note that we could actually rely solely on the DRM-device Pause/Resume events from logind and drop all the Active-Prop-Changed handling. logind guarantees proper ordering of both. However, in case we ever change weston to support multiple GPUs, we need the per-device notification. Thus, keep the code. This also makes weston more fail-safe in case logind fails to send the PauseDevice event (for whatever reason..).		12 years ago

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.
