HI， short answer is yes，you can have both emacs displayed in GUI i think the problem is when you switch to goo，the auth to DISPLAY is lost
it depends much on how you switch to goo from foo btw， i guess you login to foo with display-manager such as gdm or something alike，and switch to goo with su serveral ways a little tricky but simple to work 1. switch to goo via ssh -X goo@localhost 2. try to start emacs in this session the 2nd one is to use xauth to deal with X permission 1. as foo echo $DISPLAY （typically you will get :0） xauth list （remember the hexcode ）let's say $hex 2. as goo export DISPLAY=:0 （or what you actually get in 1） xauth add :0 . $hex （easiest way is just do a copy-and-paste） 3. try to start emas in this session you can also use “xauth merge” or “xhost”，but the principle is the same On Fri, May 3, 2019 at 23:14 aprekates <apreka...@posteo.net> wrote: > hi. in debian 9 i start emacs as user foo from the terminal and the > gui start up. i start emacs from the terminal as another user goo and > the text version comes. > > Can both users have their own gui emacs sessions ? > > > Alexandros > > > -- Liu An
