Try this:
- Become root
- Find /etc/X11/app-defaults/XScreenSaver   (it's a symlink)
- Find the lines in the file dealing with newLoginCommand
- Edit the *UN*commmented line:

*newLoginCommand	gdmflexiserver -ls       to read
*newLoginCommand	dm-tool switch-to-greeter

- Save the file
- Restart the machine

This will cause the "New Login" choice to force LightDM to start the
greeter screen where you can log in as normal to a diffrent users.

NOTE:  if you try to log in as the previous user at the LightDM login, or
later want to return to that user, you will be put back to the locked
user's session which is already running XScreenSaver.  You will need to
press a key to get to the XScreenSaver lock dialog where you will have to
log back in as that user a second time.

You can test all the above without waiting for the XScreenSaver start time
and force it immediately to lock with:
         xscreensaver-command --lock
in a terminal window.

The above is somewhat clunky but appears to get you the expected two-X
sessions running on seperate terminals.
