    This is not a duplicate, it is just poorly worded. The question is about greeters and not display managers which is why I think this question is not a duplicate of the suggestions – hanzo2001 Jul 31 '18 at 8:25

There is a nice little blog on doing this: Ubuntu 18.04 – Bring back Lightdm login manager. Here are the steps summarized from the blog:

  • To install use: sudo apt-get -y install slick-greeter
  • Verify setup using: lightdm --show-config
  • Edit the file /etc/lightdm/slick-greeter.conf to setup login screen wallpaper
  • To revert back to GDM3 login manager use sudo dpkg-reconfigure lightdm
  • Why do they install slick-greeter instead of just lightdm? Just curious. – Organic Marble Aug 3 '18 at 13:29
  • @OrganicMarble I wondered that myself. I believe you recommended lightdm to me a few months ago on a different question or answer I posted. sleek-greeter is a more targeted name. It would be to interesting to research the birthdate of the package. – WinEunuuchs2Unix Aug 3 '18 at 13:31

Simply installing the unity-greeter package will allow you to change the greeter from gdm3 to the ubuntu themed lightdm greeter.

Just run sudo apt-get install unity-greeter lightdm --no-install-recommends

During the configuration step you'll be faced with this window.


Press ↵ Enter and you'll get this choice selection screen


Use the arrow keys to select lightdm and press enter

    Yes, this works, I did it myself after installing. – Organic Marble Aug 3 '18 at 13:27
