Previously, if present_queue_vblank() failed, we simply dropped the present request on the floor, and returned an error. This was rather mean to clients - after presenting, they wait for a PresentComplete event to come back. But since the present never happens, they end up waiting forever, and lock up in poll(). This patch falls back to present_execute if present_queue_vblank fails. We still print a debugging message to warn when queueing fails, which allows us to continue debugging problems, but makes Present robust enough to not lock up people's compositing manager when vblank bugs happen. v2: Don't do present_queue_vblank() /and/ present_execute() (a bug that snuck in during last minute tidying).

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
