           Summary: [regression] Weston blocks indefinitely in
                    x11_output_wait_for_map() on raw X server
          Severity: blocker
    Classification: Unclassified
                OS: All
          Reporter: ullysses.a.eoff at intel.com

            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

When launching Weston on a raw X server (i.e. no window/display manager),
Weston blocks indefinitely in x11_output_wait_for_map and never maps onto the X
display:

It appears Weston never receives a XCB_CONFIGURE_NOTIFY event on a raw X
server.  It runs fine under a gnome X session.

Steps:
1. X -noreset :666 & sleep 1 && DISPLAY=:666 weston
