You might reasonably want to have a real video driver alongside a nested screen in a Xinerama setup, and use all your real input devices. I'm not sure the presence of a nested screen is the right hint to suppress AutoAddDevices. This seems related to Lennart's multi-seat bits, sort of. We usually want input devices bound together with particular output devices. Since a dummy or nested driver doesn't naturally have any real input devices bound to it, we wouldn't normally want any pulled in. Jamey
