Comment 2 for bug 359147

I'm going to move this to the gnome-settings-daemon package. We've now got the input-hotplug events necessary to make this happen, and gnome-settings-daemon currently handles these by setting up the monitor as it was last set.

Detecting whether the plugged monitor is a projector, and changing the behaviour based on that determination, is a policy issue which is better implemented above the kernel level.
