    LightDM is a free and open-source X display manager that aims to be lightweight, fast, extensible and multi-desktop.[4] It can use various front-ends to draw the user interface,[5] also called Greeters.[6] It also supports Wayland.[7][8]

    LightDM is the default display manager for Edubuntu, Xubuntu and Mythbuntu since the 11.10 release,[9][10][11] for Lubuntu since the 12.04 release[12] until 16.10,[13] for Kubuntu beginning with 12.10[14] until 15.04[15] for Linux Mint[16] and Antergos.

    Features

    [edit | edit source]

    Features include:

    • Codebase with very few dependencies
    • Supports different display technologies (X11 and Wayland through Mir)
    • Supports remote login (incoming – XDMCP, VNC, outgoing – XDMCP, pluggable)
    • Comprehensive test suite
    • 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 plug-ins 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.[17][18]
