LightDM is an X display manager that aims to be lightweight, fast, extensible and multi-desktop.[5] It uses various front-ends to draw login interfaces,[6] also called Greeters.[7]

Features[edit]

Features include:

  • codebase with few external dependencies
  • standards-compliance (PAM, logind, etc)
  • well-defined interface between the server and user interface
  • cross-desktop (greeters can be written in any toolkit)
  • well-defined greeter API allowing multiple GUIs
  • support for all display-manager use-cases, with plugins where appropriate

LightDM has a simpler code base than GDM and does not load any GNOME libraries to work, but at the cost of some features, that the user may or may not need.[8][9] LightDM is the default display manager for Ubuntu, Edubuntu, Xubuntu and Mythbuntu since 11.10 release,[10][11] for Lubuntu since 12.04 release,[12] and for Kubuntu beginning with 12.10[13] until 15.04.[14]
