I am trying to become a superuser. I am following these steps:

  1. terminal code: sudo passwd root

    • enter my user password
    • create root account password
    • retype root account password
  2. terminal code: sudo gedit /etc/lightdm/lightdm.conf

    • text file opens, named lightdm.conf
    • enter greeter-show-manual-login=true at bottom of text
    • save, close, restart PC

But when I go to open the text file, it is blank, and I am pretty sure that it's not supposed to be. Also, in the Terminal I am getting this line:

(gedit:17559): WARNING: Could not load Gedit repository: Typelib file for namespace 'GtkSource', version '3.0' not found


(gedit:17559): Gtk-WARNING: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

Is this right? Is the text file supposed to be? If not, how do I restore it?

why are you trying to log in as root? this is a terrible idea from a security perspective. if you say what you're actually trying to accomplish, we can probably point you in the right direction. –  strugee Mar 24 '14 at 1:24
