18.3.1.1. File Associations

The window initially has only a text box where you can enter a filename pattern to search for the matching application and a list of known applications. You can also add and remove types from the list.

When you select an application from the Known Types list, the right side of the window displays options for that file type. The General tab shows the patterns associated with the application; you can add others or select one of the patterns to remove it from the list. Clicking on the icon image opens the Select Icon window for choosing a different icon to use with that file type. Application Preference Order lists the applications associated with that type. You can add applications to the list with the Add button; select an entry to activate the other buttons. You can then move the entry up or down on the list, edit it, or remove it from the list.

On the Embedding tab, the set of radio buttons determines whether a file is viewed in Konqueror or in an application window.

18.3.3.1. Background

On the Background tab at the bottom of the window, select whether you want a flat (Solid color) background, a pattern, or one of several gradients from the Mode drop-down box. If you select a pattern, click the Setup box, and the Select Background Pattern window will open. Select a pattern from the choices or add your own, and click OK. For a pattern or gradient, choose colors for Color 1 and Color 2 by clicking on the color bars. For a flat background, choose a color from the Color 1 color bar.

On the Wallpaper tab, you can choose No Wallpaper, Single Wallpaper, or Multiple Wallpaper. If you are using wallpaper, the Mode setting determines how the image file is laid out. You can choose a tiled layout, or various centered or scaled options. If you want to use an image file as wallpaper on the background, select it from the drop-down list, or click the Browse button to look for the image on the filesystem. To use multiple wallpapers, click the Setup Multiple button. Set the time interval that each wallpaper remains on the screen. The Mode button lets you cycle through wallpaper patterns in order or randomly. Choose the wallpapers to use from the list, or click the Add or Remove button to add or remove files from the list. When viewing available wallpapers, right-click the display and choose Thumbnail Previews to see what they'll look like.

The Advanced tab sets a blending pattern for a multicolored background. The choices range from no blending to horizontal or vertical blending to various patterns and intensities.

18.3.3.2. Colors

18.3.3.3. Desktop

On the Desktop tab, select the options you want. Enable Desktop Menu places a copy of the desktop menu as a menubar at the top of the screen. Enable Icons on Desktop lets you place icons on the desktop for easy access. If you also set Show Hidden Files on Desktop, all files in the Desktop directory are displayed, including hidden files. Programs in Desktop Window lets you set a running application such as xearth as your desktop background. From the list of file types under "Show Previews for," select any for which you want a preview displayed on the desktop instead of an icon. Under "Clicks on the desktop," select the action to be taken on a left, right, or middle mouse-button click.

From the Appearance tab, select your preferred font, font size, and text color. You can also select a background color if you want to view the background box of the label. By default, the background is transparent, allowing the desktop background to be visible. Finally, you can choose to have filenames underlined.

The Number of Desktops tab sets the number of virtual desktops you can divide your workspace into. The default is 4, and you can use up to 16. The slider selects the number of desktops. The desktops are listed, numbered 1 through 16. For each enabled desktop, the listing has a usable text box next to it. You can type in a label for each desktop that will be shown in the pager display on the panel. The default labels are Desktop 1 through Desktop 16.

The Paths tab lets you set the path to the desktop, trash, and Autostart directories and to the default path for documents. In most cases, you won't need to change the defaults.

18.3.3.4. Fonts

18.3.3.5. Icons

On the Theme tab, select an icon theme. The sample icons at the top are displayed in the current theme. After selecting a theme, select Install New Theme to install it. At the bottom of the window, you can add a new theme to the list by entering the path in the text box or clicking the button at the right to open a File dialog window. You can also remove any theme except the default.

Icons are used for many purposes: in the file manager, on the panel, and so on. The Advanced tab configures icons individually for different uses. First, select the use that you want to configure from the list. For that use, select a size from the Size list, or "Double-sized pixels" to get very large, but somewhat blurry, icons. You can also choose to have the icons animated. The icon images at the bottom show how the icon will appear normally (default), when it is active (i.e., when the cursor is over it), and when it is disabled.

For each use, you can set special effects. Clicking the Set Effect button displays the Set Default Icon Effect window. From that window, select an effect and move the slider to determine the amount of that effect. For instance, choosing the To Gray effect for Active causes an icon to turn gray when you put the cursor on it. (To Gray is probably more appropriate for Disabled.) If you choose Colorize, the Color option becomes active so you can pick a color.

18.3.3.6. Launch Feedback

18.3.3.7. Panel

On the Position tab, you can choose to place the panel at the top, bottom, left side, or right side of the screen by clicking the appropriate radio button. You can set the panel alignment to Left, Center, or Right. Five settings are available to set the size of the panel to either Tiny, Small, Medium, Large, or Custom. In the Length section, you can move the slider to set the amount of the width or height of the desktop that the panel occupies. If you set it to less than 100% and click the "Expand to fit required size" button, the panel will expand to take up as much room as it needs to fit all the icons.

Figure 18-7. Panel hiding configuration

The Look & Feel tab contains settings for the appearance of the panel and its icons. Each icon is on a tile that by default is transparent, so all you see is the icon. If you set "Enable background tiles," the tiles are shown, and the settings in the middle of the window are enabled so you can enable or disable different tile types and set the background colors individually. The tile types are K-Menu, Quickbrowser, Application Launcher, Legacy Application Launcher, Window List, and Desktop Access.

Also on the Look & Feel tab, the "Enable icon zooming" setting causes icons to zoom large when you pass the mouse over them, so they appear to pop out at you. The "Show tooltips" option displays tooltips when you move the mouse over icons on the panel. To see an image on the panel background, set "Enable background image" and either enter the path to the image or browse to find one.

The Menus tab contains settings for the K menu and other menu layouts. Settings for the K menu include:

Show side image

Show a small image next to each menu entry.

Show "Bookmarks" submenu

Include a Bookmarks menu that shows your Konqueror bookmarks and lets you edit them.

Show "Recent Documents" submenu

Display a list of recently used files. Click the Clear History box to empty the list.

Show "Quick Browser" submenu

Add a browser menu for easy access to files without running the file manager. The top-level entries are Home Directory, Root Directory, and System Configuration to start from the user's home directory, the root directory, and /etc, respectively.

Detailed menu entries

Include a brief description of each menu item. If the box is not checked, only the application name is shown.

Below these settings are two columns, Available Menus and Selected Menus. The first column contains menus that are not in the K menu but can be added. The second column contains those you have selected to add. Highlight an entry in the Available Menus column and click the right-pointing arrow to move it to the Selected Menus column; do the reverse to unselect an entry. Click the Apply button to add the selected menus to the K menu. Once added, they stay in the Selected list.

To have browser menus show hidden files (i.e., dot files), select "Show hidden files in browser menus." Move the slider "Maximum browser menu entries" to change the number of entries a browser menu will display.

The Quick Start section is at the top of the K menu. Its entries consist of either the most recently used or the most frequently used applications, depending on which radio button is selected. Set the maximum number of entries shown in the Quick Start section if you want to change the default, which is 5.

The Extensions tab is active if you have added any extensions, such as a child panel or an external taskbar (by right-clicking on the panel and selecting Add → Extension). For each extension, you can locate it to the left, right, top, or bottom of the desktop, set automatic hide options, enable hide buttons, and specify the hide button size.

18.3.3.8. Screensaver

The Settings section allows you to set the amount of time the system is inactive before the screensaver starts. Type in the number of minutes in the Wait For box to set this time. If you check the Require Password box, the user must supply a password before returning to the desktop. You can also check the box "Show Password as Stars" to display the password text as asterisks instead of leaving the field blank. The Priority control lets you adjust the priority that the screensaver process has when it is run. If you have lots of important server activity, for example, set the priority to low so the performance of other programs does not suffer.

18.3.3.9. Shortcuts

You can choose the scheme used for shortcuts by selecting the KDE defaults or the current scheme if you have customized the shortcuts. The bottom section of the tab allows you to edit the selected keyboard shortcut. You can choose no key for the action, the default key, or a custom key. If you select custom, the Define Shortcut dialog appears. Here you can set or modify the primary or alternate shortcut. Click the X in the box pointing to the current shortcut, then click Multi-Key if you want to use any modifiers (Shift, Ctrl, or Alt). Finally, press the key or key combination on the keyboard that you want to use. Click Apply to save the change to the current scheme, or click New Scheme and then Save to save them as a new scheme.

The Modifier Keys tab shows the modifier keys for the current keyboard. It is not used for configuration, but is there simply to provide information.

18.3.3.10. Style

18.3.3.11. Taskbar

The Taskbar module settings include the following:

Show windows from all desktops

The taskbar shows all windows, regardless of which desktop they are on. You can then select a task and move directly to that desktop with that window active.

Show window list button

Add a menu button at the left edge of the taskbar that displays, when clicked, a list of all desktops and their windows. This is particularly useful if "Show windows from all desktops" is unchecked, since it lets you select a window on another desktop.

Group similar tasks

Combine multiple instances of any application into a single taskbar entry. The entry shows a small up-arrow. When you click on the arrow, a list of the instances appears and you can select the one you want.

Sort tasks by virtual desktop

Order the taskbar by desktop.

Show application icons

Show the application's icon along with the text on each taskbar entry.

The Actions section sets an action for each of the left, middle, and right mouse buttons. The possible actions for each are Show Task List, Show Operations Menu, Cycle Through Windows, Activate Task, Raise Task, Lower Task, and Minimize Task.

18.3.3.12. Theme Manager

Figure 18-8. Theme Manager Installer tab

If you select a theme from the list, a sample desktop image using the theme is displayed on the tab with a short text description. To apply a new theme, select from the list and click the Apply button. The selected theme is copied to your theme manager work directory (~/.kde/share/apps/kthememgr/Work).

You can also manage installed themes on the Installer tab. To install a new theme that you have downloaded, click the Add button. Specify the filename and location of the theme's .tgz file in the pop-up dialog box and click OK. The Save As button saves the currently configured theme as a separate local package without altering the original theme. The Create button works similarly, allowing you to copy your current working theme as a new local theme package. The Remove button deletes a local theme or inactivates a global theme.

The Contents tab shows the components that are configured by a theme. A theme may not have settings available for all the listed components. If a theme configures a specific component, it is listed as available. Otherwise, the component is listed as empty. Use the checkboxes to select which theme components you want to use. If you choose not to activate a specific component, information on that component from a previous theme will be used if its information is still in the theme manager work directory. If you don't want this to happen, activate the component even if it is listed as empty, and default settings will be used.

18.3.3.13. Window Behavior

On the Focus tab, the Focus Policy section sets the policy for giving a window keyboard focus and an active titlebar. The drop-down list contains four focus styles:

Click to Focus

This default focus policy requires a mouse click in a window to give it focus and raise it (bring it to the foreground).

Focus Follows Mouse

This setting causes a window to receive focus when the mouse pointer enters it. It does not come to the foreground unless the Auto Raise button is checked. The window maintains focus until the pointer enters another window.

Focus Under Mouse

This setting is similar to the Focus Follows Mouse setting, except that the window loses focus when the mouse pointer moves out of it. If the pointer is not in a window, no window has focus.

Focus Strictly Under Mouse

This setting is similar to Focus Under Mouse, but is stricter in interpreting when the mouse leaves the window.

For all the focus policies except Click to Focus, the Auto Raise and Click Raise boxes are available. One of these must be checked to be able to raise windows to the foreground. Auto Raise raises a window after a short delay, which you can set with the Delay slider.

The Keyboard section determines behavior when you use the keyboard to switch windows or desktops. In KDE mode, a box appears showing the window you are about to switch to. In CDE mode, no box appears. Check "Traverse windows on all desktops" if you want to move through all windows on all desktops. (CDE is an older desktop distributed with some commercial Unix systems.)

Figure 18-9. Windows Behavior Actions tab

The Moving tab sets window and snap zone options. The Windows section of the tab has the following settings:

Display Content in Moving Windows

Enable the display of window contents when the window is moved.

Display Content in Resizing Window

Enable the display of window contents when the window is resized.

Animate Minimize and Restore

Enable animation and activate the slider, which controls the animation speed.

Allow Moving and Resizing of Maximized Windows

Allow the use of the border on a maximized window to move or resize the window.

Placement

Choose Smart, Cascade, or Random window placement from the drop-down list to determine the initial placement of new windows on the desktop. Smart placement attempts to keep windows as uncluttered as possible. Cascade attempts to place windows in a cascaded pattern, so at least an edge of each window is visible. Random placement puts each new window randomly on the desktop.

The Snap Zones section sets the width of the zone within which a window will snap to the desktop border at the edge of the screen ("Border snap zone") or to another window ("Window snap zone"). Both zones are set with sliders and default to 10 pixels.

The Advanced tab sets options for configuring window shading, the use of Xinerama, and active desktop borders. In the Shading section, check Animate to animate window shading and unshading, and check Enable Hover to cause a shaded window to unshade if the mouse pointer remains over the titlebar for the number of milliseconds determined by moving the Delay slider.

[10]The screens also need to be configured in /etc/X11/XF86Config.

Enable Xinerama Support

Enable the use of Xinerama with KDE.

Enable Window Resistance Support

Provide some resistance when a window moves to the edge of one monitor screen so that it doesn't accidentally move onto the next.

Enable Window Placement Support

Provide support for positioning windows on any portion of the logical desktop, regardless of which monitor it falls on. If window placement support is enabled, a new window appears on the screen where the mouse pointer is.

Enable Window Maximize Support

Permit windows to be maximized across multiple monitors.

Active desktop borders enable you to switch between desktops by moving the mouse pointer to an adjacent screen edge. In the Active Desktop Borders section, the choices are:

Disabled

Turn off active desktop borders.

Only When Moving Windows

Enable active borders only when moving windows across the edge, not when moving the mouse across.

Always Enabled

Active borders are enabled both for moving windows and for moving the mouse across the edge to another desktop.

18.3.3.14. Window Decoration

The Buttons tab configures the layout of buttons that appear on the titlebars of windows. It is available only if you check "Use custom titlebar button positions" on the General tab. There are five buttons: minimize (dot), maximize (square), sticky (pushpin), close (X), and menu (dash or application-specified icon). Each button has three placement options, specified by radio buttons: left, right, or off. You can place no more than three buttons on one side of the titlebar.

18.3.4.1. Email

18.3.4.2. Preferences

18.3.4.3. SOCKS

18.3.4.4. Windows Shares

Enter your default username, default password, and workgroup in the three text boxes at the top of the window. Check the box "Show hidden shares" if you want to see shares whose names end with a dollar sign ($).

Note that entering your password and having KDE store it on the system is a security risk. If you don't enter your name or password and they are required to access the shared Windows system, you will be prompted for them. That's less convenient, but safer.

18.3.6.1. Keyboard

The Layout tab determines your keyboard layouts if you check "Enable keyboard layouts." In the Configuration section, three drop-down lists are available to set your keyboard model, primary country and language layout, and a primary variant. The options on the variant drop-down list vary depending on which primary layout you select, but generally include different keymaps for the same language.

In the "Additional layouts" section, select any other layouts you may want to use. You can also select a variant for each. The additional layouts include variations such as the Dvorak keyboard layout, in addition to language layouts. The list of layouts shows a flag image for each layout. When you enable layouts, a button is added to the system tray in the panel that allows you to switch between your selected layouts. The button contains the flag for the current layout. Click the flag to cycle through the layouts.

[11]Depending on your Linux distribution, you may not see all the lists described here.

CapsLock Key Behavior

Sets whether the Caps Lock key uses internal capitalization or acts as a shift lock key, in each case with or without canceling caps.

Third-Level Choosers

Sets the key or keys that can be used as an ISO 9995 third-level chooser. ISO 9995 is a multipart ISO standard that specifies keyboard layouts for text and office systems. The choices are Any of the Win-keys, Left Win-key, Right Control, Right Win-key, or Menu key.

Control Key Position

Determines the position of the Control key. The choices are Control Key at Bottom Left, Control Key at Left of "A", Make CapsLock an Additional Control, or Swap Control and CapsLock.

Use keyboard LED to show alternative group

Sets one of Scroll_Lock LED, Caps_Lock LED, or Num_Lock LED to show an alternative group as defined by ISO 9995.

Group Shift/Lock behavior

Determines what key is used to switch groups. Some of the options change the group until it is changed again, while others change the group only while the key is pressed. The choices are: Left Win-key changes group, Both Win-keys switch group while pressed, R-Alt switches group while pressed, Both Shift keys together change group, Right Win-key changes group, Left Win-key switches group while pressed, Caps Lock key changes group, Right Alt key changes group, or Alt+Shift changes group.

The Advanced tab configures the keyboard repeat (i.e., holding a key down repeats the character until you release the key). Check the "Keyboard repeat" box to enable keyboard repeat, and use the slider to set the keyclick volume. If you don't want to hear keyclicks, set the slider to 0. Note that your keyboard may not support changing the keyclick volume. The section "NumLock on KDE startup" determines the state of the NumLock key when KDE starts. Click Turn on, Turn off, or Leave unchanged.

18.3.6.2. Mouse

On the General tab, the Button Mapping section sets the mouse to be right-handed or left-handed. In the Icons section, select either "Single-click to open files and folders" or "Double-click to open files and folders." If you select single-click, you also have the option to check "Change pointer shape over icons" and "Automatically select icons." If you select "Automatically select icons," move the slider to determine how long the pointer can remain over the icon before it is selected. If you select double-click to open, then a single click selects an icon. Check "Visual feedback on activation" or "Large cursor" to select either of those options.

On the Advanced tab, the Pointer Acceleration slider determines how fast the pointer moves on your screen when you move your mouse. Lower values move the pointer more slowly for small mouse movements, giving you finer control. Higher values let you cross the screen more quickly. The Pointer Threshold slider sets the distance (in pixels) that the mouse must move before pointer movement occurs. The Double Click Interval slider sets the maximum time that can pass between two clicks and still be considered a double-click. The Drag Start Time slider sets the amount of time that has to pass after you click a button and start to move the mouse before it is considered a drag operation. The Drag Start Distance slider sets the distance (in pixels) that the mouse must move with a button clicked before it is considered a drag operation. The Mouse Wheel Scrolls By slider determines how many lines are scrolled for one mouse wheel movement.

18.3.7.1. Accessibility

Use sticky keys

Pressing one of the Ctrl, Alt, or Shift keys and then releasing it to press another key is treated as a multi-key combination for the next keypress. For example, to enter Ctrl-Tab with sticky keys enabled, press Ctrl, release it, and then press Tab. You can also check "Lock sticky keys." In that case, pressing Ctrl, Alt, or Shift once behaves the same as "Use sticky keys"; pressing the key twice leaves it in the modified mode until you press it again to release it.

Use slow keys

Each key must be held down for the amount of time specified by the Delay slider to be recognized as a key press. This protects you from accidental keystrokes.

Use bounce keys

The amount of time specified by the Delay slider must pass between two key presses for the second one to be recognized. This protects you from accidentally hitting multiple keys if you type fast.

18.3.7.2. Country & Language

The Numbers tab lets you set the character used for the decimal symbol, thousands separator, positive sign, and negative sign.

The Money tab lets you set the character to be used for the currency symbol, decimal symbol, thousands separator, and fract (fractional) digits, i.e., the number of digits after the decimal point. In the sections positive and negative, check the "Prefix currency symbol" box to have the currency symbol appear before the positive or negative sign, and then select where the sign should be placed from the drop-down list. The possible positions are:

Parentheses around

Display the value in parentheses. For example, you might select this option to display negative numbers in parentheses rather than showing a minus sign.

Before quantity money

Display the sign after the currency symbol and before the value.

After quantity money

Display the sign after the value and before the currency symbol.

Before money

Display the sign before both the value and the currency symbol.

After money

Display the sign after both the value and the currency symbol.

The Time & Dates tab has the following settings: Time format, Date format, Short date format, and Start week on Monday. Select the time and date formats from drop-down lists or enter a format into the appropriate text box. Check the "Start week on Monday" box if you want Monday rather than Sunday to start a new week. The time and date formats are specified with the following codes; the table shows the time codes first, then the date codes.

18.3.7.3. Crypto

If you do not have OpenSSL installed, each of the tabs displays the message "SSL ciphers cannot be configured because this module was not linked with OpenSSL." If you do have OpenSSL installed, you probably still should not make any configuration changes unless you are familiar with SSL and know what you are doing. For more information on using and configuring OpenSSL, see the O'Reilly book Network Security with Open SSL.

At the bottom of the SSL tab are some checkboxes. If OpenSSL is installed, you'll see five checkboxes; if it is not installed, only the last three are shown and available. The checkboxes are:

Use EGD

Use the entropy-gathering daemon (EGD) to initialize the pseudo-random number generator. Entropy is basically a measure of randomness; SSL requires random numbers for such functions as creating public and private keys, and EGD is a Perl script that gathers entropy.

Use entropy file

Use the file whose path you specify in the text box or by browsing as the source of entropy for the pseudo-random number generator.

Warn on leaving SSL mode

See a warning when you leave an SSL-enabled site.

Warn on sending unencrypted data

See a warning when you are about to send unencrypted data over the network with a web browser.

At the top of the SSL tab are three checkboxes that enable TLS support (if it's available), SSL v2 support, and SSL v3 support. These options are followed by two columns containing a list of SSL v2 and SSL v3 ciphers. You can check or uncheck the ciphers individually to select the ones you want to use, or use the buttons below the lists to select them in groups: Most Compatible, US Ciphers Only, Export Ciphers Only, or Enable All.

The OpenSSL tab lets you specify the path to your SSL libraries or use the Browse button to locate them. Then click on the Test button to test your settings.

The Your Certificates tab shows a list of certificates that KDE knows about and lets you manage them with a set of buttons on the right-hand side. The buttons are Import, Export, Remove, Unlock, Verify, and Change Password.

The Authentication tab lets you specify a default certificate from the drop-down button and a default action or policy. The possible policies are Send, Prompt, and Don't Send. You can also add or remove hosts and host certificates, and set one of the same three actions for each.

The Peer SSL Certificates tab lets you Export, Remove, or Verify peer organizations, and set a policy of Accept, Reject, or Prompt for each.

The SSL Signers tab lets you Import, Remove, or Restore organizations to a list of signing organizations, and determine whether to accept for site signing, accept for email signing, or accept for code signing.

18.3.7.4. Konsole

The General tab has settings to determine general Konsole behavior:

Use Konsole as default terminal application

Set Konsole as your default terminal.

Show Terminal Size when Resizing

Display the number of characters and lines as you resize the terminal. The display changes as you change the size, showing the current dimensions.

Show Frame

Put a frame around the terminal window. If the frame is turned on, a narrow edge appears inside the Konsole window around the portion that represents the terminal itself. This option does not affect the border around the entire Konsole window.

Warn for Open Sessions on Quit

Konsole warns you if you still have open sessions when you quit out of Konsole.

Blinking Cursor

The cursor blinks inside the Konsole window, making the cursor easier to find.

Require Ctrl key for drag and drop

Require the use of the Ctrl key for dragging and dropping text. Konsole allows you to drag text and drop it into other applications.

Line Spacing

Use the up or down arrows to set the line spacing. The default value is Normal, which is single-spacing.

Double Click

The text box shows a default set of characters (besides letters and digits) that are treated as part of a word when you double-click to select a word. You can add or remove characters from this set.

The Schema tab sets up the appearance of the Konsole window. The Schema box in the center of the tab shows the available schemas with the current one highlighted. The current schema also is shown in the Title box at the top. Check the box under the list of schemas to set the highlighted one as the default or click the Remove Schema button to remove it from the list. You can also set up a color scheme and add a background image to your Konsole sessions.

The Session tab lets you set properties for the different types of Konsole sessions. Pick the session type from the list in the Session section of the tab, and then enter or change the name, the command to execute, and the default directory in the General section. You can select an icon by clicking on the image of the current icon, pick a font size from the Font drop-down menu, enter or change the setting of the TERM environment variable, set the keyboard type (e.g., Linux console, VT100, or XTerm), and set the color schema for that session type.

The Write Daemon tab has a single checkbox, whose effect is to start the write daemon when KDE starts up. You should generally leave this box checked.

18.3.7.5. Passwords

Echo characters as

Determines if and how your password is echoed on the screen as you enter it. Each character can be shown as one star, three stars, or not at all.

Remember passwords

KDE will remember passwords so they don't have to be entered each time.

Timeout

If "Remember passwords" is checked, this option becomes available to set the period of time for the passwords to be remembered. For example, you might set a timeout period of an hour if you are temporarily doing work that requires superuser privileges.

18.3.7.6. Session Manager

The section "Default action after logout" has three options that control what action takes place by default when you log out. Check one of: Login as Different User, Turn Off Computer, and Restart Computer. The default action applies only if you logged in through the kdm display manager. You can always choose a different option if you let the system prompt you for confirmation.

18.3.7.7. Spell Checking

18.3.9.4. System Notifications

This module allows you to enable and configure sound events for different applications. Most of the window is taken up with a tree listing of applications and events. For each event, you can select among four choices for how you want to be notified:

Log to file

Log the event to a file, specified in the Filename text box below.

Play sound

Play the sound contained in the file specified in the Filename text box below. You can also check the box "Use external player" to use a particular media player and enter the path to the player in the text box.

Show messagebox

Display the notification in a message box displayed in the program's window.

Standard error output

Write the message to the standard error output.

You can select more than one option. For example, you might want to hear a sound and also have the event logged to a file.

18.3.10.1. Date & Time

18.3.10.2. Font Installer

The Anti-Alias tab lets you set up options for antialiasing with the XRender Extension. If your system is not capable of using this extension, the checkboxes under the Configuration File text box are grayed out. If they are available, you can check "Exclude range" and enter the end points of the range to exclude certain point sizes from antialiasing, and check "Use sub-pixel hinting."

If you are in administrator mode, you can click the Advanced button to set up rules for matching font families and establish any desired include directives specifying additional font files. The Include Directives tab has two sections. Any files listed in the top section, Include, must be available. Files in the bottom section, Include If, are included if they are found, but aren't required.

The Settings tab has customization settings for five aspects of font installation:

18.3.10.3. Login Manager

The Appearance tab lets you edit the greeting string displayed on the login screen. Certain special characters, such as %s and %n in the default greeting string, can be used; they are replaced as follows:

You can choose a logo if you want one, or select Show Clock to display a clock instead of a logo. To select a logo other than the default KDE logo, click the logo image and select another image file. A drop-down list offers you a choice of GUI styles for the login screen. Use the Echo Mode drop-down list to choose whether to replace each character of the password with a single star, three stars, or no echo. The Language option lets you select the default character encoding for kdm.

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. See the earlier description of the Background module in the Look & Feel section for a detailed description of the options on this tab.

The Sessions tab configures session settings. There are two drop-down lists at the top that set who is allowed to shut down the system from the console and remotely. The choices for both are Everybody, Only root, and Nobody. The default for the console is Everybody; the default for remote shutdown is Only root.

The Commands section allows you to set the commands used for shutdown and restart. In the Lilo section, check "Show boot options" to enable the LILO boot options to be displayed in the Shutdown menu. The Session Types section configures the list of session types available to the user 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.

The Users tab lets you show a list of users on the login screen. The users are listed by username with a logo displayed for each user. To log in, you can simply click your logo to automatically enter your name into the login box, but you still must supply your password. The tab contains listings labeled "Remaining 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 click the "All but no-show" button to display users in both the "Remaining users" and "Selected users" lists. No-show users are user IDs that are used to control access-restricted system resources (e.g., root, news, and nobody). They are never displayed on the login screen. You can add the names of other users to the no-show list. Check the "Sort users" box to display the images in alphabetical order.

You can select a different default image by clicking on the image button and choosing another image file. You can also select a unique image for each user by highlighting the user in one of the lists and selecting an image file for that user.

Users whose image is not shown on the login screen can still log in; the only difference is that they have to enter their login name as well as their password.

18.3.11.8. User Agent

The User Agent module allows you to specify the user-agent string reported by the browser for sites that may not recognize Konqueror, or anything that's not a major commercial web browser. Check the box "Send browser identification" to send information about your browser; it is recommended that you leave this checked for the use of host sites that customize the page they send depending on the browser. The user-agent string contains the name and version number of the client program making the request. The default for Konqueror at the time of this writing is "Mozilla/5.0(compatible;Konqueror/3)". Check the boxes below the default identification to customize the information sent; the example is updated to reflect your choices. The options are:

Add operating system name

Adds the name of your operating system to the identification; e.g., Linux.

Add operating system version

If you checked the box to add the operating system name, you can also check this box to add the version.

Add platform name

Adds the name of your platform; e.g., X11.

Add machine (processor) type
