When I turn my computer on a screen comes up asking me for a password. This is not the typical Ubuntu log in screen, but it looks like the Gnome log in.

enter image description here

Usually this gives me a choice of what to log in to: Unity, Gnome, Gnome no effects, etc.

This time around I have no choice, it just takes me into the current version of Gnome (don't know to call this the shell or Gnome 3).

Everything works fine, but the normal Unity session is missing, as are the other Gnome options.

How do I get the option to select Unity back?

    Yes, the "not typical Ubuntu log in screen", we need to figure that out first. Feb 26, 2013 at 14:21

Since lightdm is the default in ubuntu, a different login screen means you installed some other display manager. It seems that you are currently using gdm, so to revert back just input this line in the terminal:

sudo dpkg-reconfigure gdm

and choose lightdm as the default display manager.

  • This looks like it will restore the login, but will it bring back the Ubuntu/Unity option? Feb 26, 2013 at 16:48
  • If you have Unity installed (which I assume you have), it will. Feb 26, 2013 at 19:24
  • Bingo. Problem solved. Thank you to everyone for your help. Feb 26, 2013 at 20:39
