LightDM is a free and open-source X display manager that aims to be lightweight, fast, extensible and multi-desktop.

[5] It can use various front-ends to draw the user interface,[6] also called Greeters.

[7] It also supports Wayland.

[8][9] LightDM is the default display manager for Edubuntu, Xubuntu and Mythbuntu since the 11.10 release,[10][11][12] for Lubuntu since the 12.04 release[13] until 16.10,[14] for Kubuntu beginning with 12.10[15] until 15.04[16] for Linux Mint[17] and Antergos.

Features include: 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.
