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
