The X Window System by default uses the 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. Users can pick their session type on a per-login basis. GDM 2.38.0 is the last version that features customization with themes; subsequent releases do not support themes.
GDM comprises the following components:
Until version 2.22, GDM had a few Easter eggs, in the form of strings to be entered in the username box. These can be found in the source file "gui/guilogin.c", in a function named "evil".
- Dancing login – type "Start Dancing" to start, and "Stop Dancing" to stop.
- (This requires the standard greeter ("GTK+ Greeter"), rather than the graphical one ("Themed Greeter")).
- "Gimme Random Cursor" – can be used repeatedly.
- This changes the mouse cursor to a randomly selected 1 of 77 different "cursor fonts" as defined in the X11 specification.
- "Require Quarter" (or "Require Quater", for backward compatibility with a typo in the original), then log in normally – a dialog box that reads "Please insert 25 cents to log in." appears after entering the password. Clicking "OK" allows the login process to proceed as normal.
