GDM - GNOME Display Manager
GDM (GNOME Display Manager) is the default graphical login manager for the GNOME desktop environment. It provides the login screen, manages user sessions, and supports both X11 and Wayland.
🧩 Key Features of GDM:
- Graphical login interface: Presents a polished, user-friendly login screen.
- Session management: Lets users choose between desktop environments and session types (e.g., GNOME on X11 or Wayland).
- Accessibility: Offers built-in support for screen readers and other assistive technologies.
- Security: Runs the login screen as a separate user (gdm), isolating it from user sessions.
🛠️ Technical Details:
- Written in C and maintained by the GNOME Project.
- Supports Wayland and X11, automatically launching the appropriate session.
- Highly integrated with GNOME, but can also be used with other desktop environments.
🧭 Usage and Configuration:
Default in Ubuntu, Fedora, and other GNOME-based distributions. Configurable via /etc/gdm/custom.conf for settings like autologin, Wayland enablement, and session defaults.
