Welcome
Congratulations for selecting SUSE LINUX. A few clicks are all that is needed to
prepare the installation, which takes fifteen to twenty minutes. After configuring the users and their passwords and selecting the screen resolution, your SUSE
LINUX system is ready for use. If you are familiar with earlier versions of SUSE
LINUX, you will notice how much the configuration with the system assistant
YaST has been expanded and simplified.
Get to know the graphical desktop environments KDE and GNOME and learn
how to adapt them to your personal preferences. The following sections introduce some very useful and interesting programs from the large range of available
applications in different categories, including office programs such as OpenOf-
fice.org, web browsers, programs to manage your schedule, file managers, scanning tools, and image editing programs.
Additionally find information about the SUSE help system and the available information sources containing further documentation. Also included are a list of
frequently asked questions about SUSE LINUX.
Changes in the User Guide
The following is a list of the changes introduced in this guide, as compared to the
previous version (SUSE LINUX 9.1):
The instructions for the installation and configuration with YaST have been
moved to the Administration Guide.
The following chapters have been revised:
.
The chapter about OpenOffice.org now includes a section discussing
the migration of MS Office documents to the OpenOffice.org formats.
.
The chapter about GNOME has been updated to reflect the current
version.
.
The chapters about the KDE desktop, KOrganizer (schedule manager),
KAddressbook (contact organizer), KMail, and about synchronizing
handhelds with KPilot have been updated to match the current version
of KDE.
Typographical Conventions
The following typographical conventions are used in this book:
/etc/passwd: files or directories
hplaceholderi: replace the character string hplaceholderi (including the angle
brackets) with the actual value
PATH: an environment variable
ls: commands
user: users
Alt : a key to press
‘File’: menu items, buttons
Acknowledgements

The KDE Desktop
The KDE desktop offers an intuitive graphical interface. The following sections
show you how to make efficient use of KDE’s features and how to customize the
desktop to meet your personal needs. This is followed by an introduction to the
file manager Konqueror and a brief description of some small but useful utilities.

1.1 Desktop Components
The main components are the icons on the desktop and the panel at the bottom
of the screen. The mouse is your most important tool. Click a symbol or an icon
once to start the associated program or the file manager Konqueror. If you rightclick an icon, different menus appear, depending on the program. As well as the
icons, there are two desktop menus.
1.1.1 The Desktop Menus
If you middle-click the desktop (if your mouse only has two buttons, press both
buttons at the same time), a window and desktop management menu is displayed. The menu lists the various desktops and the windows opened in them.
Click one of the following menu items:
‘Unclutter Windows’ If you have several windows on your desktop, they are
placed next to each other and aligned with the top left corner.
‘Cascade Windows’ Starting from the top left corner, the windows on the desk-
top are placed on top of each other in such a way that only the top and left
borders of the lower windows are visible.
‘Desktop x’ Desktop 1 is your default desktop. This part of the menu lists all
the windows currently opened. You can bring them to the foreground by
clicking one of the respective items.
‘Additional Desktops’ You can use the additional (virtual) desktops provided
and switch to them with the menu or the panel. All functions are available
on all desktops. This limits the number of programs and associated windows that need to be arranged on one desktop. These virtual desktops resemble additional desks in your office.
If you right-click the desktop, a more complex menu is displayed, allowing you
to customize your desktop.
‘Create New’ Use this menu item to create new directories, files, or devices on
the desktop. A list of possible elements is provided for selection in a submenu.
6 1.1. Desktop Components
‘Bookmarks’ The bookmark editor allows you to create, group, change, or
delete bookmarks. The bookmarks are used by the browser and file manager Konqueror. The bookmark editor also allows you to import bookmarks from other browsers, such as Mozilla, Netscape, Opera, and Internet
Explorer.

The KDE Desktop
‘Run Command. .. ’ This menu item opens a window in which to enter a com-
mand manually. The command is executed after pressing
‘Undo’ Use this item to undo the last action. For example, if you have just cre-
ated a new directory on the desktop, clicking this item reverts the creation
so the directory disappears.
‘Paste’ To keep a folder or document handy on the desktop, you can copy an
icon from the file manager by right-clicking and selecting ‘Copy’ then moving the mouse to the desired location on the desktop. Right-click again and
select ‘Paste’. The icon is now available on your desktop and can be moved
around by dragging it with the left mouse button pressed.
‘Icons’ This allows you to rearrange the icons on the desktop. You can also
change the order of the icons.
‘Windows’ This arranges the windows on the desktop, either on top of each
other begining from the top left corner or next to each other.
‘Refresh Desktop’ If the desktop should appear garbled in some way, use this
menu item to redraw it.
‘Configure Desktop. .. ’ This menu item starts a configuration dialog with which
to configure the appearance and behavior of the desktop. Details about the
configuration of the desktop are provided in Settings on page 13.
‘Start New Session’ This menu opens a dialog box asking if you want to start a
new user environment. After clicking ‘Start New Session’, the current session disappears into the background and the system switches to a new login screen. Each session has a function key assigned to it:
first session,
sions, press
the desired session.
F8 the second one, and so on. To switch between different ses-
Ctrl -
Alt -
Fhx i , where
Fhx i is the function key corresponding to
Enter .
F7 represents the
‘Lock Screen’ If you leave your workstation and do not log out, you should use
this function to prevent others from gaining access to your files. Depending
on the setting, the screen turns blank or starts displaying a screensaver. To
continue using the computer, enter your password.
7SUSE LINUX
‘Logout’ Log out of your system if you are not going to use the system for some
time.
1.1.2 The Trash Bin
The trash bin is a directory for files marked for deletion. Drag icons from the file
manager or the desktop to the trash bin icon by keeping the left mouse button
pressed then release to drop them there. Alternatively, right-click an icon and select ‘Move to Trash’ from the menu. Click the trash bin icon to view its contents.
You can retrieve an item from the trash if desired.
Files removed with ‘Delete’ are not kept in the trash bin, but permanently deleted
right away. To permanently delete the files in the trash bin itself, right-click the
trash bin icon and select ‘Empty Trash Bin’.
1.1.3 CD-ROM, DVD-ROM, and Floppy Disks
If you click the floppy disk icon when a floppy disk is inserted, the file manager starts and displays the content of the floppy disk. Display a context menu
with various options by right-clicking the individual icons on the floppy disk.
It is also possible to move the icon to a different location, such as the desktop or
your home directory, by simply keeping the left mouse button pressed over it and
dragging it to the destination. You will be asked whether you want to move or
copy the file or create a link. The same technique can be used to copy or move
files from your home directory to the floppy disk.
Right-click the floppy disk icon to access the context menu. ‘Unmount’ is a very
important option. Be sure to unmount the drive before removing a floppy disk
from the drive, because this is necessary to trigger the actual writing of the data
to the floppy disk.
The handling of CDs and DVDs is similar, with the only difference that these media are not writable. Despite this, you must unmount CD and DVD drives, because otherwise you will not be able to remove the disk from the drive. You can
also select ‘Eject’, which causes the medium to be unmounted and ejected. Both
methods only work if the CD or DVD is no longer accessed and any file manager
window displaying the content of the CD or DVD has been closed.
8 1.1. Desktop Components
1.1.4 The Printer Icon
Right-click the printer icon and choose ‘Actions’ ➝ ‘Print files’. The KPrinter di-
alog window starts. This program enables you to adjust a number of settings
and send print jobs directly. The upper part of the main window, like that in Figure 1.1, shows the selected printer. To switch to another printer, click the arrow
next to the printer name and select the device to use from the list displayed.

To configure the selected printer, click ‘Properties. . .’. A configuration dialog like
that shown in Figure 1.2 on the following page opens, enabling you to change the
paper format (e.g., from A4 to letter) or to select a different paper tray. Changing
trays is especially useful if one of the trays contains letterhead paper and another
contains plain white paper.

Under ‘Orientation’, choose between ‘Portrait’ and ‘Landscape’ and whether the
pages should be turned 180 degrees so that they are printed upside down. To the
right of ‘Orientation’, specify the settings for two-sided printing. If ‘None’ is selected, only one page is printed per sheet. If you select ‘Long side’, the front and
back are printed like in a book. With ‘Short side’, the back is printed reversely
and you must turn the sheet up to view the text correctly. With ‘Start:/End:’,
specify whether your document should have start or end banners, such as “confidential” or “secret”. Under ‘Pages per Sheet’, select to print two or four pages
on one sheet. For this purpose, the pages are downsized accordingly. If you click
‘Save’, your settings are saved and used again for the following print jobs. However, if you click ‘OK’, the settings only apply to the current job. If you close the
dialog with ‘Cancel’, all changes are discarded.
After making all settings, click ‘Expand’. The second part of the window now

becomes visible. Click the blue folder icon. By default, your home directory is displayed. Select a file and confirm with ‘OK’. You can also select the file by doubleclicking it. The respective file then appears in the overview of the main window,
together with the name, type, and path specification. Now click ‘Print’ to send
the job to the printer. The job is placed in the queue and can be monitored with
KJobViewer. On the other hand, if you click the document, two additional buttons become active to the right. Use the X button to remove the document from
the selection or use the magnifying glass icon to display, edit, and save the file
with Kwrite or OpenOffice.org (depending on the document type). Afterwards,
simply close the editing program and click ‘Print’ in the KPrinter dialog. The
printout will reflect any changes made to the document while editing.
All KDE applications use KPrinter for printing. For example, if you click the
printer icon in KWrite, the KPrinter dialog appears. The file to print is already preselected.
1.1.5 The Panel
The panel at the lower edge of the screen consists of several areas. By default, the
icon for the main menu is located to the far left. Other icons are next to it. The
house icon provides quick access to your home directory with all subdirectories.
The other icons start applications, such as OpenOffice.org, K-Mail, and the web
browser Konqueror, if these programs were installed.
Next to these icons are the numbered buttons with which to switch desktops.
These multiple desktops enable you to organize your work if you use many programs simultaneously, as if you had several desks for various tasks.
The taskbar is located next to the virtual desktops. All started applications are
displayed in the taskbar. If you click a window title in the taskbar, the application is moved to the foreground. If it is already in the foreground, clicking minimizes the application. If you click it again, it reopens. Next to the taskbar, find
applets, such as the clipboard Klipper, SuSEwatcher, and any other applets you
have started. The clock helps you keep track of the time.
If you right-click an empty space in the panel, a menu providing the usual help
and configuration options for the panel is displayed. Use the menu to change the
size of the panel and to add or remove applications. To add an application, search
for it in the menu and select it. Remove applications or applets by right-clicking
the corresponding icon and selecting ‘Remove’ from the displayed menu.

12 1.1. Desktop Components
1.2 Settings
The KDE desktop can be customized according to your preferences and needs.
‘Control Center’ in the main menu opens the configuration dialog for your KDE
desktop. The following section introduces a number of modules.
1.2.1 Peripherals
This opens the configuration dialogs for the mouse, keyboard, and printer administration.
Keyboard
Keyboard Repeat Keeping a key pressed causes the associated character to be
printed repeatedly as long as the key is pressed. The option is activated by
default.
NumLock on KDE Startup Here, determine whether the number pad of your
keyboard should be active when KDE is started.
Key Click Volume If you want to hear a sound when a key is clicked, activate
this option and adjust the volume with the slider.
Mouse
The mouse configuration comprises three tabs: ‘General’, ‘Advanced’, and
‘Mouse Navigation’. The configuration options of the ‘General’ tab are:

The KDE Desktop
Button Mapping Here, specify right-handed or left-handed use of your mouse.
Icons Determine how the system should react to clicks and double-clicks. The
default setting for the KDE desktop is a single click for opening files or folders and a mouse pointer that changes its appearance when it is moved over
icons. To use double-click for opening files and folders, select ‘Double-click
to open files and folders (select icons on first click)’. Finally, set the size and
color of the pointer and the kind of visual feedback given when programs
are started.
Under the ‘Pointer Theme’ tab, choose among a number of themes to give the
mouse pointer an appearance to your liking. The configuration options of the
‘Advanced’ tab are:
13SUSE LINUX
Pointer Acceleration The pointer acceleration defines the relation between
the speed with which you move the input device (mouse) and the pointer
speed as displayed on the screen. The higher the selected factor is, the more
difficult it is to control the screen pointer.
Pointer Threshold The threshold (in pixels) specifies the distance the pointer
must move before the specified pointer acceleration actually comes into
force. In this way, you have exact control over the mouse pointer when
moving it a small distance, but you can still cover a large distance on the
screen with a flick of the wrist.
Double Click Interval Here, set the maximum interval between two mouse
clicks that should still be interpreted as a double-click.
Drag Start Time An object selected with a click is moved only if you continue to
move the pointer for the specified period (in milliseconds).
Drag Start Distance An object selected with a click is moved only if you drag it
the minimum distance specified (in pixels).
Mouse Wheel Scrolls By If you have a wheel mouse, specify the number of
lines the selected element should scroll with each wheel notch.
To be able to navigate the mouse pointer with the arrow keys of the number pad,
activate this function under ‘Mouse Navigation’ and customize the parameters
according to your needs.
Printers
The printer administration module mainly consists of three parts. The top frame
lists all printers available in the network. The center part features a configuration
and information zone comprising four tabs. The lower part indicates the current
print system type. The following description only covers the configuration part.
Note
The configuration options relevant for your daily work with the system can be accessed under ‘Jobs’ and ‘Instances’. ‘Information’ and
‘Properties’ mainly provide information or are used for system administration.
