A number of GDM settings are now managed within GConf.
The GDM default greeter is called the simple Greeter and is configured via GConf. Default values are stored in GConf in the gdm-simple-greeter.schemas file. Use gconftool2 or gconf-editor to edit these values. The following options exist for the Greeter:
/apps/gdm/simple-greeter/banner_message_enable
false (boolean)
Controls whether the banner message text is displayed.
/apps/gdm/simple-greeter/banner_message_text
NULL (string)
Specifies the text banner message to show on the greeter window.
/apps/gdm/simple-greeter/logo_icon_name
computer (string)
Set to the themed icon name to use for the greeter logo.
/apps/gdm/simple-greeter/disable_restart_buttons
false (boolean)
Controls whether to show the restart buttons in the login window.
/apps/gdm/simple-greeter/wm_use_compiz
false (booleans)
Controls whether compiz is used as the window manager instead of metacity.
Plugins can also be disabled using GConf. For example, if you want to disable the sound plugin then unset the following key: /apps/gdm/simple-greeter/settings-manager-plugins/sound/active.
