The kernel is supposed to set this when drmModeSetCrtc() is called but at least the i915 driver wouldn't do that in all cases. A fix for this should be released with kernel 3.10, but we work around the issue in older kernels by always forcing DPMS to ON when doing a mode set. https://bugs.freedesktop.org/show_bug.cgi?id=64873
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.
