That is the basic idea, but we have to see what we can get. Some
discussion is happening on the gnome-cc list.

Generally there will be always need for the configuration file or some
kind of overwriting infrastructure. Think of drivers that do not support
XRandR 1.2 or the bulletproof x. Currently it seems that Fedora will
push a capplet that can only deal with XRandR 1.2 what doesn't seem to
be sufficient. I would like to see a hook in the gnome-settings-daemon
that allows to start an alternative configuration tool if the GNOME tool
doesn't provide any backend plugins.
