Just don't run a display manager at all!  That's the part that does the
greeter screen and login prompting.  Since that's what actually launches
the X session when you log in, it comes back to life on logout and
re-displays the graphical login screen.

But you can start an X server without a display manager (i.e. startx).
When you quit X, there's no display manager going, so you'll be back at a
system prompt.
