Exploring the Desktop Components
After logging in to KDE for the first time, you see the KDE desktop. It consists of the following basic elements:
Figure 1.2 Example KDE Desktop
Figure 1.2 Example KDE Desktop
Desktop Icons and Desktop Folder Desktop icons represent files, directories, applications, functions, and removable media, like CDs or DVDs. Click an icon on the desktop to access its associated program or application. By default, your desktop icons are shown in a Desktop Folder, a transparent region of the screen showing the contents of the Desktop folder in your home directory. If you drag an icon from the Desktop
Folder and drop it on another part of the desktop, it appear as widget that you can tilt, enlarge or minimize. Widgets are small applications that can be integrated into your desktop. Right-click to open a context menu to access the icon properties, or to remove the icon. For more information, see Configuring Widgets (page 42).
Desktop Context Menu: Right-click an empty area on the desktop to access the context menu for configuring the appearance of the desktop, adding panels or widgets to the desktop, locking the widgets in their current position, or for leaving the current session or locking the screen.
KDE Panel: The panel (in KDE also called "Kicker") is a bar, typically located at the top or the bottom of the screen. By default, the panel of your KDE desktop consists of the following areas (from left to right): quick launcher with the main menu icon on the left and further program icons, pager (desktop previewer), taskbar, and system tray. You can add or remove icons in the panel and customize the appearance of the panel as well as its location on the desktop. If you hold your mouse pointer over an icon in the panel, a short description is displayed.
Quick Launcher: The quick launcher contains the main menu button and some larger icons that are shortcuts to frequently used programs, folders, and functions.
Main Menu Button: Use the icon at the far left of the panel to open a menu holding a search function at the top and several tabs at the bottom. The Applications tab shows all installed programs in a function-oriented menu structure which makes it easy to find the right application for your purpose even if you do not know the application names yet. For more information, refer to Section 2.1.1, "Using the Main Menu" (page 15).
Pager (Desktop Previewer): Between the quick launcher and the taskbar, find a miniature preview that shows your virtual desktops (if not configured otherwise, they are numbered). openSUSE allows you to organize your programs and tasks on several desktops, which minimizes the number of windows to arrange on the screen. To switch between the virtual desktops, click one of the symbols in the pager. For more information, refer to Section 2.6, "Using Virtual Desktops" (page 28).
Taskbar: By default, all started applications and open windows are displayed in the taskbar, which allows you to access any application regardless of the currently active desktop. Click to open the application. Right-click to see options formoving, restoring, or minimizing the window.
System Tray: This rightmost part of the panel usually holds some smaller icons, including the system clock displaying time and date, the volume control, and several other helper applications such as the device notifier, informing you about recently plugged or inserted devices such as USB sticks, external hard disks, cameras, CDs, or DVDs. For more information, refer to Section 2.5, "Accessing Removable Media and External Devices" (page 27).
The integration and handling of desktop objects has changed from KDE 3.x to KDE 4, which now uses a new desktop and panel interface tool called Plasma. Plasma supports desktop widgets (also called "plasmoids"), similar to Apple's dashboard widgets. Learn more about the key desktop objects in the following sections.
1.2.1 Locking and Unlocking Desktop Objects
With KDE 4, desktop elements can be locked in their current position to prevent them from being moved around on the desktop. As long as the desktop elements are locked, you cannot add, move, or remove any objects to and from your desktop.
To lock or unlock the desktop elements, right-click an empty space on the desktop and select Lock Widgets or Unlock Widgets.

Find how to add, remove and configure widgets and change numerous desktop elements in Chapter 3, Customizing Your Settings (page 37).
1.2.2 Desktop Icons
By default, the Desktop Folder showing the contents ofthe -/Desktop folder, displays the following icons by default:
Figure 1.4 KDE Desktop Folder
The My Computer icon is very useful for viewing the most important information about your hardware, network status, disks (hard disks, removable media, and external devices), operating system, and some common folders at one glance. For example, find processor type and speed listed there, information about your RAM and the current swap status, or your graphics card. OS Information lists the most important information about your operating system such as the Kernel version included, the current user, version number and type of the operating system, and the KDE version number. openSUSE ships with a number of further tools (either graphical or command line tools) that you can use to get more detailed information about your system. If you need detailed hardware information about your system, use the YaST hardware probing, described in Section "Probing Your Hardware" (Chapter 2, Setting Up Hardware Components with YaST, tStart-Up).
Opens the Firefox Web browser. For more information, refer to Chapter 17, Browsing with Firefox (tApplication Guide).

KDE's clipboard tool that "remembers" the last entries you have moved to the clipboard. To view the clipboard contents, click the Klipper icon or press Ctrl + Alt + V. The most recent entry is listed on top and is marked as active with a black check mark. To insert the active clipboard entry again, move the mouse pointer to the target application, then middle-click. For more information, see Section 2.3, "Moving Text between Applications" (page 24).
Your desktop's default mixer, KMix helps you to control sound on your desktop after your sound card has been detected and configured with YaST, the central tool for installation and configuration of your system. By default, clicking the KMix icon in the system tray shows the master controller with which to increase or decrease the overall volume. For more information, refer to Section "Mixers" (Chapter 22, Playing Music and Movies: amaroK, Kaffeine and More, tApplication Guide).
Helps you keeping your system up to date. When you connect to the Internet, the openSUSE Updater automatically checks whether software updates for your system are available. The applet icon changes color and appearance depending on the availability of updates for your system. For detailed information about how to install software updates with openSUSE Updater and how to configure openSUSE Updater, refer to Chapter 5, YaST Online Update (tReference).
If you manage your network connection with NetworkManager and have enabled the use of NetworkManager in YaST, the KNetworkManager icon also appears in your system tray be default. Use it to change and configure network connections. For detailed information, refer to Chapter 10, Using NetworkManager (tStart-Up).
For information about the current date and time, click the clock in the system tray or hove your mouse pointer over the clock. You can change the clock settings (such as appearance or additional data to be displayed) from the context menu available upon right-click. If you need to update the system time, start YaST and select System > Date and Time. Refer to Section "Clock and Time Zone" (Chapter 1, Installation with YaST, tStart-Up) for more information.
Locks your screen and starts the screen saver. Access to the session can only be regained with a password.
