+Subject: [PATCH] switchMonitor: Fix initial selection on desktop
+
+Due to !2056 the monitor config is 2 instead of 4 on the desktop.
+However, the constant `Meta.MonitorSwitchConfigType.UNKNOWN` is fixed to
+4, and may cause the initial selection to be out of index thus fail to
+display the switcher.  This replaces the above constant to the actual
+length of the switcher items.
+
