'''GNOME Display Manager''' ('''GDM''') is a graphical [[X display manager|displaylogin manager]] (a[[X graphicaldisplay [[loginmanager|"display manager"]]) for the [[windowing system]]s [[X11]] and [[Wayland (display server protocol)|Wayland]].

The X Window System by default uses the [[XDM (display manager)|XDM]] display manager. However, resolving XDM configuration issues typically involves editing a [[configuration file]]. GDM allows users to customize or troubleshoot settings without having to resort to a [[Command-line interface|command line]]. Users can pick their [[Login session|session]] type on a per-login basis. GDM 2.38.0 is the last version that features customization with [[Skin (computing)|themes]]; subsequent releases do not support themes.
