Depending on your X setup, you can have issues if you open a term, su to root
and then try to run emacs as emacs will try to run the X version. This can fail
if you don't have the appropriate xauth cookies (which control access to the X
display). 

The simplest way to get around this is to run emacs with the -nw switch so that
it will run within the term rather than trying to run as an X client. 

Of course, far simpler is just to use tramp.

Some setups hide this stuff and manage the .Xauthority cookies in a way that
makes all this 'invisible' to the end user. Some people even suggest using the
xhost command to grant access to your X display, but this is insecure,
especially if running on a multi-user system.
