Comment 3 for bug 1242939

fyi / i have 3 different systems and 3 different outcomes.

- new install 13.10 on new machine, no issue

- clean upgrade from 13.04 to 13.10 where adding lightdm to hidden-users solved the problem

- bad upgrade 13.04 t 13.10 where 13.10 had to be re-installed but /home was changed to old raid drive.
  in this instance, adding lightdm to hidden-users only solves after a logout and coming back to the login screen. the initial after boot screen still shows the Light Display Manager user.
