DGA only handles master devices but it does intercept slave device events as well (since the event handlers are per event type, not per device). The DGA code must thus call into UpdateDeviceState to reset the button/key state on the slave device before it discards the remainder of the event. Test case: - Passive GrabModeSync on VCP - Press button - Enable DGA after ButtonPress - AllowEvents(SyncPointer) - Release button The button release is handled by DGAProcessPointerEvent but the device state is never updated, so the slave ends up with the button permanently down. And since the master's button state is the union of the slave states, the master has the button permanently down.

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
