You can change how the login screen looks, who has +access using the login manager and who can shutdown the +computer. + +In order to organize all of these options, this module is +divided into six sections: Appearance, +Font, Background, +Sessions, +Users and +Convenience. + +You can switch between the sections using the tabs at the top of +the window. + +If you are not currently logged in as a superuser, you +will need to click the Administrator Mode +Button. You will then be asked for a superuser password. Entering a +correct password will allow you to modify the settings of this +module. + + +Appearance + +From this page you can change the visual appearance of &kdm;, +&kde;'s graphical login manager. + +The greeting string is the title of the login screen. If the +string contains the word HOSTNAME it +will be translated to the domainless name of the machine &kdm; is +installed on. + +You can then choose to show either the current system time, a logo +or nothing special in the login box. Make your choice in the radio +buttons labeled Logo area. Using the +Positions setting, you can choose to either center +the content of the logo area or to position it using fixed +coordinates. + +If you chose Show logo you can now choose a +logo: + + + +Drop an image file on the image button. + + +Click on the image button and select a new image from the image chooser +dialog. + + + +If you do not specify a logo the default +$KDEDIR/share/apps/kdm/pics/kdelogo.png +will be displayed. + +While &kde;'s style depends on the settings of the user logged in, +the style used by &kdm; can be configured using the GUI +Style option. + +Below that, you have two dropdown boxes to choose the language and the +country for your login box. + + + + +Font + +From this section of the module you can change the fonts used in +the login window. + +You can select three different font styles from the drop down box +(Greeting, Fail, +Standard). When you click on the Change +font button a dialog appears from which you can select the +new characteristics for the font style. + + + +The Greeting font is the font used for the title +(Greeting String). + + +The Fail font is used when a login fails. + + +The Standard font is used in all other places in the +login window. + + + +An example of each font can be seen in the +Example Box. + + + + +Background + +Here you can change the desktop background which will be displayed +when a user logs in. You can have a single color or an image as a +background. If you have an image as the background and select center, the +selected background color will be used around the image if it isn't +large enough to cover the entire desktop. + +The background colors and effects are controlled by the options on +the tab labeled Background and you select a +background image and its placement from the options on the tab labeled +Wallpaper. + +To change the default background color(s) simply click either of +the color buttons and select a new color. + +The dropdown box above the color buttons provides you with several +different blend effects. Choose one from the list, and it will be +previewed on the small monitor at the top of the window. Your choices +are: + + + +Flat +By choosing this mode, you select one color (using the color +button labeled Color 1), and the entire background is +covered with this one color. + + +Pattern +By choosing this mode, you select two colors (using both color +buttons). You then select a pattern by clicking +Setup. This opens a new dialog window, which gives you +the opportunity to select a pattern. Simply click once on the pattern of your +choice, then click on OK, and &kde; will render the pattern +you selected using the two colors you selected. For more on patterns, see the +section Background: Adding, Removing and Modifying +Patterns. + + +Background Program +By selecting this option, you can have &kde; use an external +program to determine the background. This can be any program of your choosing. +For more information on this option, see the section entitled Background: Using an external program. + + +Horizontal Gradient +By choosing this mode, you select two colors (using both color +buttons). &kde; will then start with the color selected by Color +1 on the left edge of the screen, and slowly transform into the +color selected by Color 2 by the time it gets to the +right edge of the screen. + + +Vertical Gradient +By choosing this mode, you select two colors (using both color +buttons). &kde; will then start with the color selected by Color +1 on the top edge of the screen, and slowly transform into the color +selected by Color 2 as it moves to the bottom of the +screen. + + +Pyramid Gradient +By choosing this mode, you select two colors (using both color +buttons). &kde; will then start with the color selected by Color +1 in each corner of the screen, and slowly transform into the color +selected by Color 2 as it moves to the center of the +screen. + + +Pipecross Gradient +By choosing this mode, you select two colors (using both color +buttons). &kde; will then start with the color selected by Color +1 in each corner of the screen, and slowly transform into the color +selected by Color 2 as it moves to the center of the +screen. The shape of this gradient is different then the pyramid +gradient. + + +Elliptic Gradient +By choosing this mode, you select two colors (using both color +buttons). &kde; will then start with the color selected by Color +2 in the center of the screen, and slowly transform into the color +selected by Color 1 as it moves to the edges, in an +elliptical pattern. + + + +The setup button is only needed for if you select Background +program or Patterns. In these instances, +another window will appear to configure the specifics. +Wallpaper +To select a new background image first, click on the +Wallpapers tab, then you can either select an image from the +drop-down list labeled Wallpaper or select +Browse... and select an image file from a file +selector. + +The image can be displayed in six different ways: + + +No wallpaper +No image is displayed. Just the background colors. + + +Centered +The image will be centered on the screen. The background colors +will be present anywhere the image does not cover. + + +Tiled +The image will be duplicated until it fills the entire +desktop. The first image will be placed in the upper left corner of the screen, +and duplicated downward and to the right. + + +Center Tiled +The image will be duplicated until it fills the entire +desktop. The first image will be placed in the center of the screen, and +duplicated upward, downward to the right, and to the left. + + +Centered Maxpect +The image will be placed in the center of the screen. It will +be scaled to fit the desktop, but it will not change the aspect ratio of the +original image. This will provide you with an image that is not distorted. + + + +Scaled +The image will be scaled to fit the desktop. It will be +stretched to fit all four corners. + + + + + + +Sessions + +Allow to shutdown +Use this dropdown box to choose who is allowed to shut down: + + +None: No one can shutdown the computer using &kdm;. +You must be logged in, and execute a command. + + +All: Everyone can shutdown the computer using +&kdm;. + +Root only: &kdm; requires that the +root password be entered before shutting down the +computer. +Console only: The user must be at this +console, to shut down the computer. + + +Commands +Use these 3 blanks to define the exact shutdown command. +The shutdown command defaults to: + +/sbin/shutdown + +The restart command defaults to: + +/sbin/reboot + +The Console mode (which restarts the computer as a console only terminal) +defaults to: + +/sbin/init + +When Show boot options is enabled, &kdm; will on reboot +offer you options for the lilo boot manager. For this feature to work, you will +need to supply the correct paths to your lilo command and to +lilo's map file. + + + +Session types + +Define which session types should be accessible from the login +window. + + For more information on this subject, look at /etc/X11/xdm/Xsession to find your +xdm setup files. Also review the xdm man pages, especially under the SESSION +PROGRAM section. + +To add a session, type its name in the +blank entitled New types, and click +Add new. + +To remove a session, select the session from the list and click +Remove. + + + + + + + +Users + +From here you can change the way users are represented in the +login window. + +As you look on this window, you will see three lists (All users, +selected users, and no-show users). You also see an image box, and a +set of options along the right side of the window. + +The first thing you must decide, is if you are going to show users +or not. + + +If you choose to show users, then the login window will show +images (which you select), of a list of users. When someone is ready to +login, they select their user name/image, enter their password, and they +are granted access. + +If you choose not to show users, then the login window will be +more traditional. Users will need to type their username, and password +to gain entrance. This is the preferred way if you have many users on +this terminal. + + +To show (and sort) or not to show users + +Along the right edge of the window are two check boxes: + +If Show users is selected, you have chosen to +show images of users, instead of making them type their login +name. + +If Sort users is selected, then the list of +users will be sorted alphabetically in the login window. If unchecked, +users will be listed in the same order as they are on this page. If +Show users is not checked, this has no +effect. + + + + +How to determine which users to show and which users to hide + +Below the user image box, and above the Show +users check box, is a set of two radio buttions: + + +Show only selected users: If this option is selected, only the +users contained in the list labelled Selected Users, will +be displayed in the login window. If Show users is not +checked, this has no effect. +Show all users but no-show users: If this option is selected, +all users will be listed, except those users contained in +the list entitled No show users. If Show +users is not checked, this has no effect. + + + + + +Select users + +This page contains three listboxes. The large listbox on the left +shows all the users on the system which might be a genuine user. + +The top rightmost listbox shows the selected users and the bottom +rightmost listbox shows the users we don't want displayed in the login +window. + +To move a user from one listbox to another you click on the +username in the listbox and click >> to +move the user from the leftmost box the the rightmost box or +<< to move the user from the rightmost box +to the leftmost box. + + + + +Images + +This section of the manual only applies if Show +users is selected. If it is not, this image box has no +effect. + +Every user on the system can be represented by a image. The image +for the user is kept in a file called +$KDEDIR/share/apps/kdm/pics/users/$USER.xpm. +If the user doesn't have such a file the file +$KDEDIR/share/apps/kdm/pics/users/default.xpm +will be used instead. + +To assign a new image to a user just select the user in one of the +listboxes and either drop an imagefile on the image button to the right +or click on the image button and select a new image from the image +selector. + +If no user is currently selected you will be asked if you want to change +the default image. + +The replacement is performed by a &konqueror; process so if the +image file already exists you will be prompted by &konqueror; if you +want to replace it. If you confirm the image will be replaced - you will +not have to press the Apply +button. + + + + + + +Convenience + +In the convenience tab you can configure some +options that make life easier for lazy people, like auto login or +disabling passwords. + +Please think more than twice before using these +options. Every option in the convenience tab is +well-suited to seriously compromise your system security. Practically, +these options are only to be used in a completely non-critical +environment, ⪚ a private computer at home. + + +Automatic Login + +Automatic login will give anyone access to a certain account on +your system without doing any authentication. You can enable it using +the option Enable auto-login. + +Automatic login comes in two flavors: truly automatic +login acts like you would expect automatic login to, &ie; +&kdm; will automatically login without expecting any input from the +user. Enable this using the Truly automatic login +option. If this option is not enabled, &kdm; will start normally, +enabling you to login as any user, and will only perform automatic login +if you kill the X server, ⪚ by pressing &Ctrl;&Alt;Backspace. + +You can choose the account to be used for automatic login in the +list below. + + + + +Password-less Login + +Using this feature, you can allow certain users to login without +having to provide their password. Enable this feature using the +Enable password-less logins option. + +Below this option you will see a list of users for which a password +is required, as well as a (by default, empty) list of users that do not +need to provide a password. When Enable password-less +logins is enabled, you can move users from one list into the +other, by selecting them and then clicking the +>> and << +buttons. + +Again, this option should only be used in a safe +environment. If you enable it on a rather public system you should take +care that only users with heavy access restrictions are granted +password-less login, ⪚ +guest. + +The Automatically login after X server crash +option allows you to skip the authentication procedure when your X +server accidentally crashed. Show previous user +will show the name of the last login already entered into the login +field in &kdm;. Some site administrators would consider even this a +possible security weakness, because potential attackers then know at +least one valid login. + + + + + + + + +
