Sugar does not understand standard D-Bus protocol for RANDR configuration

[bernie]

Since we lack our own UI for configuring monitors and video modes, it is tempting to use gnome-display-settings for the purpose.

gnome-display-settings creates a settings file in ~/.config/monitors.xml and then invokes a few D-Bus methods to notify gnome-settings-daemon that it should update the screen configuration. This is easy to see with dbus-monitor.

Perhaps we could implement the same protocol in Sugar. I don't know the details, but hopefully it's a freedesktop standard implemented by other desktops as well.

Would be great if someone could check if it's a standard or what.
