I misunderstood you.  Your problem is a little more difficult, since the
local X display is probably owned by another login process.  Here is one
way of handling the situation.  As the display owner run:

xhost + at localhost

This allows anyone on the local machine to gain access to the X display.
This does pose some security risks. Then when you login using SSH, you
can run:

export DISPLAY=:0.0

Now you should be able to access the local display.  If you are remotely
logged in as the same user, you should only have to export the correct X
display.  The xhost command appears to be unnecessary, since the
same .Xauthorty file is used.

The other method is to export the Xcookie database for the use owning
the display to the user running the remote command.  I will leave it as
an exercise how you would export the cookies to the other user.
