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
