With an un-patched GNU Emacs you can't start GNU Emacs via  
emacsclient. When emacsclient can't contact a running server, it will  
tell you this and quit. So you need to launch GNU Emacs.

There can't be a difference between a server started from GNU Emacs  
running in some terminal emulation or being the client of some window  
system just as a spoon is a spoon, no matter whether it's in your  
mouth, in a drawer, in a dish-washer, or in a shop.

As long as GNU Emacs keeps running in some terminal emulation that  
survives stopping of the X server and that is (again) authorised to  
contact the new X server and open clients on this display, it should  
work.

Me, I can't see how the terminal emulation can survive X server's  
end. You're logging in without window system and you're starting it  
by hand?


Another option is to use session and desktop. These can re-establish  
GNU Emacs's state before it was quit. The only problem is that you  
have to quit GNU Emacs by hand. If it receives a signal from the  
crashing or quitting X server, it does not save the recent state. At  
least I have not found a way to achieve this ...
