openSUSE® provides the tools that Linux* users require in their daily activities. It comes with an easy-to-use graphical environment, the GNOME* desktop, that communicates with the underlying Linux system, to let you access and manage files, folders, and programs. openSUSE provides an integrated suite of applications for a wide range of office, multimedia, and Internet activities. The LibreOffice suite, which allows you to edit and save files in a number of formats, is also included. The office suite is available for several operating systems. Therefore, you can use the same data across different computing platforms.

3.1. Getting Started

When you start your system, you are usually prompted to enter your username and password. If someone else installed your system, check with your system administrator for your username and password.

After logging in to GNOME for the first time, you see the GNOME desktop, offering the following basic elements:

Desktop Icons:  Access programs and features on your system by double-clicking an icon. Right-click an icon to get additional menus and options. By default, the desktop features several key icons, including your personal Home folder and a trash can for deleted items. Other icons representing devices on your computer, such as CD drives or USB flash disks, may also be present on the desktop, and you can add as many icons on your desktop as you like. If you double-click your Home folder, the Nautilus file manager starts and displays the contents of your home directory.

Bottom Panel:  The desktop includes a panel at the bottom of the screen. This panel contains the Computer menu, the Tomboy Notes applet, a taskbar to display buttons for all currently running applications, and the system tray. You can also add applications and applets to the panel for easy access.

Main Menu:  Click Computer on the left side of the bottom panel to open the main menu. Commonly used applications appear in the main menu along with recently used applications. Click the Documents button to display your recent documents, or click the Places button to display your favorite places (such as your home directory, your desktop, or available network servers). Click More Applications to access additional applications, listed in categories. Use the options on the right to access help, open the Центр управления GNOME, run YaST, install additional software, lock your screen, log out of the desktop, shut down the system, or check the status of your hard drive and network connections.

System Tray:  The right side of the bottom panel shows some smaller icons, including the system clock that displays the current date and time, the Workspace Switcher, the volume control, and icons for several other helper applications.

Taskbar:  By default, all applications running on the current desktop are displayed in the taskbar (the area in the middle of the panel between the Computer button and the system tray). You can access these applications by clicking their names in the taskbar. Right-click the application's name to see options for moving, restoring, or minimizing the window.

Desktop Menu:  Right-click an empty spot on the desktop to display a menu with various options. Click Create Folder to create a new folder on the desktop. Use Create Launcher to create a launcher icon for an application. Provide the name of the application and the command for starting it, then select an icon to represent it. You can also change the desktop background, open a terminal, create a document, and align desktop icons.

3.1.1. Modifying Desktop Panels

The bottom panel can be customized to meet your individual needs, and additional panels can be added and configured to further personalize your desktop.

To add a new panel, right-click a blank space in the bottom panel and select New Panel. To delete a panel, right-click a blank space in the panel and select Delete This Panel. openSUSE requires that at least one panel is left on the desktop.

3.1.2. Adding and Removing Panel Icons

  1. Right-click a blank space on the panel and select Add to Panel.

  2. Browse to the desired program and double-click it to add it to the panel.

  3. To remove a program icon from a panel, right-click its icon in the panel and select Remove From Panel.

3.2. Starting Programs

Start programs from the Main Menu or from the command line, using a shell or the Run Command. Additionally, you can start programs from the desktop or the panel by left-clicking the program icon once.

3.2.1. Using the Main Menu

To run a program in openSUSE, click Computer on the panel to open the main menu screen. If the program you want does not appear in the main menu screen, click More Applications to view a list of all available applications grouped in categories. You can also limit the list to show only applications with a specific name by entering all or part of the name into the Filter field. Click an entry in the list to start the corresponding program.

You can also add an icon to your panel that opens a more traditional version of the main menu. Right-click a blank space on the panel, select Add to Panel, then double-click Traditional Main Menu.

If you already know the name of an application but are not sure how to start it from the main menu, use the Search field in the main menu. Click Computer, type a portion of the application name in the Search field, then press Enter. If the application is installed on your system, the name of the application appears in the Needle search dialog box. Click the name to start the program.

3.2.2. Using the Run Application Dialog

Press Alt+F2 to open the Run Application dialog. Type a command, for example, f-spot, and press Enter or click Run to start the application. The command to start the application is often (but not always) the application name written in lowercase.

3.3. Handling Media

If you insert a CD or DVD into your drive or plug in a pluggable device (for example, a USB stick or removable hard disk), GNOME opens Nautilus and shows the content of the media.

3.4. Customizing Your Desktop

3.4.3. Using the Центр управления GNOME

In addition to letting you change individual desktop elements, GNOME lets you extensively personalize your desktop. You can find more settings to adjust the overall appearance and behavior of your desktop in the Центр управления GNOME. There, you can also change fonts, keyboard and mouse configurations, regional and language settings, parameters for your Internet and network usage, and more.

To start the Control Center, click Computer, then click Control Center on the right of the main menu.

3.5. Applying Desktop Effects

If your computer supports a 3D graphics card with Xgl, you can use graphical effects like turning your desktop into a rotating 3D cube, enabling translucent or transparent windows, and zooming in and out of the desktop screen. You can also use other window effects such as shadows, fading, and transformations. If you do not have a 3D graphics card, some effects may be disabled or reduce the performance of your system. If the performance of your system is too low, disable the compositing effect for your current session with Alt+Shift+F12.

To configure the effects on your desktop, proceed as follows:

  1. Start the personal settings window as described in Раздел 3.4.3, «Using the Центр управления GNOME».

  2. Select Look and Feel+Desktop Effects and choose Enable Desktop Effects. If your graphic card does not support 3D, you will be notified.

  3. Select the effects in one of the tabs.

3.6. Using Virtual Desktops

The desktop environment allows you to organize your programs and tasks on several virtual desktops. If you often run a lot of programs simultaneously, this minimizes the number of windows to arrange on your screen. You might, for example, use one desktop for e-mailing and calendaring and another for word processing and graphics applications.

3.16. Managing Your Digital Image Collection

F-Spot is a management tool for your collection of digital images, tailored for the GNOME desktop. It allows you to assign different tags to your images in order to categorize them, and offers various image editing options. For example, you can remove red-eye, crop, and adjust brightness and colors. F-Spot supports all important image formats, including JPEG, PNG, TIFF, and several vendor specific RAW formats.

You can import photos from your hard drive, your digital camera, or your iPod. You can also use F-Spot to create photo CDs, generate a Website gallery, or export your photos to your Flickr, 23, Picasa Web, or SmugMug account.

To access F-Spot, click Computer+F-Spot Photo Browser or press Alt+F2 and enter f-spot. The first time you run F-Spot, you must define the location from where you want to import images into your collection. If you already have a collection of images stored on your hard drive, enter the path to the directory and (optionally) include subfolders. F-Spot imports these images into its database.

Thumbnails of your images are displayed in the right part of the window, and detailed information for a selected image is displayed in a sidebar to the left. By default, your photos are displayed in reverse-chronological order, so your newest photos are always at the top. You can sort your photos in chronological order or reverse-alphabetical order by clicking View+Reverse Order.

A menu bar at the top of the window allows you to access the main menus. A toolbar below offers several different functions depicted by a matching icon.

3.17. Managing Your Music and Videos

Use Banshee to import CDs, sync your media collection to a digital media player, play music directly from a digital media player, create playlists with songs or videos from your library, create audio and data CDs from subsets of your library, and subscribe to, download, and listen to your favorite podcasts.

When you start Banshee for the first time, you need to import your media to make them available in the library. To do so, select Media+Import Media from the menu. Choose an import source and click Import. After successfully importing your media, you can access them from your library.

To play a song or a movie, simply select it in the library and click the play button. You can also use the buttons in the upper left corner to pause a song or play the next or previous song. Use the loudspeaker button on the right to adjust the volume.

Banshee also has an integrated CD player. When you insert a music CD, your CD title appears in the left panel. Select the title and click the Play button to play your full CD.

To create audio and MP3 CDs, select the songs you want, then click the Edit+Write CD from the menu.
