+	RRSetOutputPrimary marks 'output' as the primary output for the
+	screen with the same root window as 'window'. This output's CRTC
+	will be sorted to the front of the list in Xinerama and RANDR
+	geometry requests for the benefit of older applications. The
+	default primary output is None, and None is a legal value to pass
+	to RRSetOutputPrimary. This request is expected to be used by
+	desktop environments to mark the screen that should hold the primary
+	menu bar or panel.
+
+	If the named output is not connected to any CRTC, or if the Window
+	and Output are not attached to the same screen, BadMatch is generated.
+	In the latter case, errorValue will be the Window, not the Output.
+
+	As this changes the logical layout of the screen, ConfigureNotify
+	and RRScreenChangeNotify will be generated on the appropriate root
+	window when the primary output is changed by this call. This request
+	also generates RROutputChangeNotify events on the outputs that gained
+	and lost primary status.
+
+	If an output is disconnected asynchronously (eg. due to recabling),
+	the primary status does not change, but RROutputChangeNotify events
+	will be generated if the hardware is capable of detecting this;
+	clients are expected to reconfigure if appropriate.
+
+	If an output is deleted (eg. due to device hotplug), the server will
+	act as though None was passed to RRSetOutputPrimary, including
+	generating the appropriate events.
