A display manager, or login manager, is a graphical interface screen that is displayed at the end of the boot process in place of the default shell. There are various types of display managers, just as there are various types of window and desktop managers. There is usually a certain amount of customization and themeability available with these managers.

Loading the display manager

Many display managers come packaged with a systemd service file.

Simply run the following command in accordance with the display manager you choose:

  • GDM:
# systemctl enable gdm.service
  • KDM:
# systemctl enable kdm.service
  • SLiM
# systemctl enable slim.service
  • LXDM:
# systemctl enable lxdm.service
  • LightDM:
# systemctl enable lightdm.service
  • SDDM:
# systemctl enable sddm.service

The next time you reboot, the display manager should run. The display manager will load automatically after start-up and will respawn in the event of a crash.
