Re: Running emacs as root

[gebser]

If you're running Unix/Linux you first need to make it okay for others
(even root) to use your X.  So do "xhost +127.0.0.1" (without the
quotes).  You'll need to do that only the first time.  Then do

su - -c "export DISPLAY=0:0;emacs"

The first dash says 'use root's environment'.  The '-c ...' specifies 
the command to run; in the double quotes is actually two commands 
(separated by the semi-colon), but Unix/Linux doesn't care.  

You could also alias this whole command to something easier to remember 
if you want.
