Start a server every time that you start your computer, from a 
terminal you can do:

#+BEGIN_SRC shell
 emacsclient -c -a '' 
#+END_SRC

every time that you want to open emacs. That will start a server 
if there is none or connect if there is one already. You will be 
able to connect to that server even from TTY1, and M-x 
save-buffers-kill-emacs if you want a clean exit.

But I guess the relevant question is, why is your X hanging?
