Ratpoison && detaching X11 like 'screen does
I read this Parg:
"Since all my processes are running on the desktop, if something goes wrong with my laptop, I can reattach my session on the desktop and go on working. Since I don't rely exclusively on GUI applications, if something goes wrong that prevents me from running X, if I'm placed in an environment in which I can't run X, or if I want to persist in my untested but heartfelt belief that not running X saves battery life, I can be happy with the console."
but I don't think Ratpoison can do this.... as something else, like 'xmove', is required. Please correct me if I'm wrong.
