If we VT switch away between picking a cursor surface and actually doing the pageflip in drm_output_repaint(), we never set output->cursor_view to NULL. Then we unplug all the input devices and as the last pointer device goes away we destroy the cursor surface. Then when we switch back, we call drm_output_set_cursor() with an invalid surface and crashes. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=73566
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.
