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
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.[18][19]
