this has nothing to do with su, you have to allow the root user to
connect to your X-Server.
The X-Server is running under your normal user.
First you should allow localhost to connect to your x-server. Under your
normal user use
to allow connections.
Now use su to switch to root user
You should then set your DISPLAY variable:
if its not set.
Now emacs should work.
Another way is to use ssh with PublicKey Authentication and X11
Forwarding. In that way i do not have to type password.
