http://cgit.freedesktop.org/xorg/proto/randrproto/tree/randrproto.txt is the RANDR protocol documentation. In particular, RROutputChangeNotify will be sent when outputs are hotplugged. As I said this works in the netbook UX, the chain of events being: hardware -> intel_915 kernel driver -> udev -> intel X driver -> RANDR event -> gnome-settings-daemon It's just passing a "display connected" message all the way to g-s-d, which then applies policy.
