Erm, a "server layout" is much more than a display layout...

A "Server layout" is the "root" of the entire config. "Layout switching"
involves eventual dual head configs and switching between them,
different input devices, color depths, etc etc etc. Just for example,
switching from single head to dual head is all but trivial, not even
speaking about depth switching.
