Looks like you're asking for something like suspend or hibernate to me.
What's the point in replicating features that do this perfectly? Better
spend your energy in fixing them if they don't work on your box.

FWIW, GNOME upstream considers suspending the normal way of stopping
your session - even to the point where it's very hard to reboot, which
is debatable...
