Login Window Configuration

To change the login window, use the Login Screen Setup window accessible by choosing System Administration Login Window. This configures the GNOME Display Manager (GDM), which runs your login process. Here you can set the background image, icons to be displayed, the theme to use, users to list, and even the welcome message. You can also set up an automatic login for a particular user, skipping the GDM login screen on startup. Login screens can be configured for local or remote users. You can choose between a plain screen, a plain screen with face browser, or a themed screen. The Local tab lets you select what screen to use for local logins, and you can browse among available themes. From the Remote tab, you can select Plain, select Plain With Browser, or use the same configuration used for your local logins.

On the Users tab, you can select which users you want displayed when using a face browser. On the Local tab, you can choose from a number of themes. The Ubuntu theme is selected by default. You can also opt to have the theme randomly selected. On the Security tab, you can set up an automatic login, skipping the login screen on startup. You can even set a timed login, automatically logging in a specific user after displaying the login screen for a given amount of time. In the Security area of the tab, you can set security options such as whether to allow root logins or allow TCP (Internet) access, as well as setting the number of allowable logins. Click the Configure X Server button to open a window for configuring X server access. Check the GNOME Display Manager Reference Manual, accessible with the Help button, for details.

You can configure automatic login for a particular user on the Login Window Preferences configuration’s Security tab. This feature is useful for single-user systems in which the same user logs in.
