1.3 Desktop Components

The graphical desktop environment should not pose any problems for former Windows or Macintosh users. The main components of the desktop are the icons on the desktop and the panel at the bottom of the screen.

Figure 1-2 An Example KDE Desktop

Desktop icons represent files, directories, applications, functions, and removable media, like CDs or DVDs.

The desktop has the following icons by default:

Trash

Contains files and folders that have been deleted. For information about using the trash bin, see Section 1.3.4, Managing the Trash Bin.

My Computer

Displays information about hardware, network status, operating system, hard disks, common folders, and removable devices. For more information, refer to Section 1.3.3, Accessing Removable Media.

Network Browsing

Displays network services you can access. Some of the services might require authentication. To learn more, refer to Section 9.0, Accessing Network Resources.

Printer

Opens KJobViewer that displays print jobs you have sent to printers. See Section 12.4, Starting Print Jobs in KDE for more information.

Firefox

Opens the Firefox Web browser. For more information, refer to Section 14.0, Browsing with Firefox.

Office

Opens a new OpenOffice.org document. For an introduction to this office suite, refer to Section 3.0, The OpenOffice.org Office Suite.

The panel (in KDE also called Kicker) is a bar, typically located at the top or the bottom of the screen. It is designed to provide information about running applications or the system and easy access to some important functions or applications. If you hold your pointer over an icon, a short description is displayed.

Figure 1-3 KDE Panel (Kicker)

The panel typically consists of the following areas:

Main Menu Icon

By default, the left end of the panel has an icon that opens the main menu, similar to the start button on the MS Windows desktop. The main menu has a well-ordered structure for accessing the main applications. It also contains menu items for major functions like logging out or searching for applications. For more information, see Section 1.3.1, Accessing the Main Menu.

Quick Launcher

Next to the main menu icon, find the quick launcher. It holds some icons for the most important functions or applications to enable you to start them without going through the main menu. It also contains an icon for the Help Center, which provides online help for your system.

Desktop Previewer

Next to the quick launcher, find the desktop previewer, which shows your different desktops. These virtual desktops enable you to organize your work. If you use many programs simultaneously, you might want to run some programs in one desktop and other programs in the other desktop. To switch between desktops, click the desktop symbol in the panel.

Taskbar

The taskbar is located next to the desktop previewer. 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. 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.

System Tray

The rightmost part of the panel usually holds the system clock, the volume control, and several other helper applications.

To learn how to configure the appearance and behavior of your desktop, including the main menu, desktop icons, or the panel, refer to Changing Panel Elements.

1.3.1 Accessing the Main Menu

Open the main menu by clicking the icon to the far left of the panel. Alternatively, press Alt F1 . The main menu is subdivided into these sections: Most Used Applications, All Applications (a menu with all applications sorted according to categories), and Actions. Applications that you start most often appear in the Most Used Applications section.

The function-oriented menu structure makes it easy to find the right application for your purpose even if you do not know the application names yet. If you already know the name of an application (or at least a part of its name) but are not sure how to start it from the main menu, you can use the search function provided in the All Applications section.

Figure 1-4 Main Menu Search Function

Just type a part of the application name into the search field without pressing the key afterwards. If the application is installed on your system, the menu structure leading to this application is highlighted in the main menu.

The following section provides information about a number of actions that can be triggered from the main menu.

Recent Documents

Lists the most recently opened files or folders. When you select a document, the application to view or edit this document is started. You can also clear the history of documents.

My System

Gives quick access to some places often needed, such as your home directory or media devices.

Run Command

Opens a dialog where you can enter an command to start the application. The name of the command is often (but not always) the application name written in lowercase. You can use autocompletion of the command by typing the first letters then pressing . If the command was executed before and can be uniquely identified, it is completed to full length.

Switch User

To start a second session with a graphical user interface on your machine, select Start New Session. Your current session remains active while you are taken to the login screen where you can log in as a different user. You can access the first session by pressing F7 . To access a new session, press F8 instead of F7. Additional sessions can be accessed by pressing F9 to F12.

Lock Session

If you leave your computer you can prevent unauthorized access by others by locking your screen. After locking, a screensaver starts. Access to the session can only be regained with a password. To unlock, enter your normal login password.

Log Out

Opens a dialog with several options: you can end the current session, turn off the computer, restart the computer, or cancel the logout. End Current Session leaves your system running and restores the applications for your next login. If your system provides power management, you are also offered to suspend the computer, making the next system start much faster than a complete boot.

1.3.2 Inserting or Connecting Removable Media

If you insert or connect removable media to your computer (such as CD-ROMs, digital cameras, or USB sticks), these are usually automatically detected. In KDE, a dialog appears, showing the medium type detected and offering several options of what to do with the new medium. The list of options depends on the type of medium inserted.

Figure 1-5 Autodetection of a USB Stick in KDE

To view the data with a file manager, select Open in New Window and click OK. The Konqueror file manager appears, showing the contents of the removable device.

Figure 1-6 Viewing the Contents of an USB Stick

If you want the same action to be performed every time you insert a removable medium of that type, activate Always do this for this type of media in the autodetection dialog before clicking OK.

Configuring How to Handle Removable Media

In the autodetection dialog, you can also configure how KDE should handle several types of removable media. For example, if you know that a certain type of medium that you use often always contains photos, you can configure it to open an image viewer application automatically:

  1. In the autodetection dialog, click Configure.

  2. A configuration dialog appears, showing a list of all available actions.

  3. Click the Medium types drop-down list and select the type of medium for which to configure a certain action. The list of available actions now only shows actions applicable to the medium type selected.

  4. Select the action to apply and click Toggle as Auto Action.

    Figure 1-7 KDE Configuration Dialog for Removable Media

  5. Click the Advanced tab and make sure the Enable medium application autostart after mount check box is selected.

  6. Click OK to apply the changes and close the configuration dialog. Now every time you insert a medium of this type, the configured action is executed automatically and the autodetection dialog does not appear any more.

To reset the action assigned to the type of medium and restore the default options, proceed as follows:

  1. Start the KDE Control Center from the main menu by selecting Personal Settings.

  2. In the left-hand navigation bar, click Peripherals Storage Media . The configuration dialog appears on the right.

  3. Click Default and Apply. The next time you insert a medium, the autodetection dialog appears again, leaving you the choice of what to do with the medium.

1.3.3 Accessing Removable Media

KDE offers several ways to access removable media at any time. Clicking My Computer on the desktops opens a view as shown in Figure 1-8.

Figure 1-8 My Computer

If you start Konqueror as a file manager (see Section 1.4, Managing Folders and Files with Konqueror) and click Storage Media on the start window or enter media:/ in the location bar, Konqueror displays the storage devices as shown in Figure 1-9.

Figure 1-9 Displaying Media in Konqueror

You can also name removable devices, such as USB sticks, with Konqueror. Right-click the USB stick in Konqueror and select Properties. On the General tab, enter a name in the input field and click OK. When inserting the stick the next time, Konqueror displays the name of the stick.

A small green arrow indicates that a medium has been mounted (integrated into your file system, which is necessary to access the data on the medium). In SUSE Linux Enterprise Desktop, you normally do not have to care about mounting removable devices because this is done automatically by default.

NOTE: Removing Media Safely

If you want to remove or disconnect a medium from your computer, make sure that the data on the medium is currently not accessed by any application or user. Otherwise risk a loss of data. To safely remove the medium, proceed as follows:

  1. Open a view that displays all removable media.

  2. Right-click the medium to remove and select Safely Remove or Eject. Safely Remove unmounts the medium after which you can disconnect the medium from your computer. Eject automatically opens the CD or DVD drive of your computer.

1.3.4 Managing 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 moved to the trash bin, but deleted completely. To delete the files in the trash bin completely, right-click the trash bin icon then click Empty Trash Bin.
