I'm sorry, I should have mentioned that I tried that, but then my 
DISPLAY environment variable is not set so I can not use the graphical 
emacs. I can, of course, set DISPLAY manually but it would be a nuisance 
to do that every time I log in as user2.

It's not quit clear to me when I should use a login shell and when not. 
IMO the bash documentation only explaines the differences, not why the 
different shells exist.

I'm guessing the solution will involve tweeking my system, not my emacs 
settings, so I probably should go to another newsgroup. Still, any help 
from here would be appreciated.

E.g. where is the DISPLAY variable set normally (when I log in as 
user1)? I'm using debian linux.
