Usually it's a user session daemon that asks the driver to change the mode upon receiving the event that a monitor as been (un)plugged.
The problem is that the nvidia driver doesn't implement the API that the usual daemons in GNOME, KDE, etc. are using to do just that which is XRandR >= 1.2 IIRC.
So, join your voice to the choir asking nvidia to implement that ;-)
