LightDM
LightDM is a lightweight, cross-desktop display manager used to handle graphical logins on Linux systems. It provides the login screen (called a greeter) and manages user sessions, including authentication and session launching.
🧭 Key Features of LightDM:
- Lightweight and fast: Designed to use minimal system resources compared to heavier alternatives like GDM (GNOME Display Manager).
- Cross-desktop compatibility: Works with GNOME, KDE, Xfce, LXDE, and other desktop environments.
- Greeter flexibility: Supports multiple greeter front-ends, such as:
- LightDM GTK Greeter (default for many distros)
- Slick Greeter (used by Linux Mint)
- Webkit Greeter (HTML/CSS-based)
- Remote login support: Includes protocols like XDMCP and VNC for remote graphical sessions.
- Guest sessions and autologin: Can be configured for temporary guest accounts or automatic login.
