The Appearance tab lets you edit the greeting string displayed on the
login screen and choose a logo. A drop-down box offers you a choice of the
GUI style of the login screen: either Windows or a Motif style. The
Language option on this tab lets you select the default character
encoding for the login manager.
The Fonts tab lets you choose the font style and size for the
Greeting, Fail, and Standard screen messages. Select which type you
want to configure from the drop-down list and click the Change Font
button. The pop-up window shows a list of available fonts and lets you
set the point size. Click the OK button to close the pop-up window.
The font you have chosen is displayed in the Example area of the tab.
The Background tab lets you select the background for the login
screen. Like the desktop background, you can choose a color or
wallpaper to use.
The Users tab allows you to show a list of users on the login screen.
The users are listed by username with a logo above the login boxes. A
user can simply click her logo to automatically enter her name into
the login box, but she still must supply her password. The tab
contains listings for all users, selected users, and no-show users.
You can select names from the lists and use the arrow buttons to move
them from one box to another. Two options are available for who to
display on the login screen. You can place names in the selected
users list and click the Show Only Selected Users button.
Or, you can edit the all users list and click the Show All Users But
No-Show Users button. No-show users are user IDs that are used to
control access-restricted system resources (e.g., root, news, and
nobody).
The Sessions tab configures session settings. The drop-down list at
the top sets who is allowed to shut down the system. You have the
choices None, All, Root Only, and Console Only. The Commands section
allows you to set the commands used for shutdown and restart. The
Session Types section configures the list of session types that a
user can log into from the login screen. The Default list contains
the various environments that are installed on your system such as
KDE and GNOME. You can add a new type or remove a type from the
listing.
