user visible monitor hotplug events

[Kai-Uwe Behrmann]

Hello,

what's the way to get monitor hotplug events in a user desktop session?
I want to setup ICC profiles during monitor connections and
deconnections. Currently this is done inside Compiz. But I want to put
the setup code into a speperate application. Ideally this application
would be called on demand.

Is DBus the right thing to register to? If yes, how?

Code examples are welcome too if any.

kind regards
Kai-Uwe
