Chapter 2. Overview of the GNOME Desktop

This chapter introduces you to the features and main components of the GNOME Desktop. Before you start to use the desktop environment read this chapter to familiarize yourself with the various features, and how the main components work. The desktop environment is very configurable, so this chapter describes the typical default configuration, covering the following topics.

Introducing Desktop Environment Components

When you start a desktop environment session for the first time, you should see a default startup screen, with panels, windows, and various icons. Figure 2.1 shows a typical desktop environment.

Figure 2.1. A Typical Desktop Environment

A typical desktop environment. Callouts: Menu Bar, Top edge panel, Desktop, Windows, Window List applet, Bottom edge panel, Workspace Switcher applet.

The major components of the desktop environment are as follows:

  • Panels

    Panels are areas in your desktop environment from which you can access all of your system applications and menus. Panels are very configurable. A particularly important panel in Figure 2.1 is the top edge panel. The top edge panel includes the Menu Bar. The Menu Bar contains two special menus, as follows:

    • Applications menu: Contains all applications and configuration tools. This menu also includes the file manager and the help browser. To start the file manager, choose Home Folder from the Applications menu.

    • Actions menu: Contains various commands that perform desktop environment functions, for example Search for Files and Log Out.

    Click on the icon at the extreme right of the top edge panel to display a list of all open windows.

  • Menus

    You can access all desktop environment functions through menus. The top edge panel contains menus, so you can use a combination of menus and panels to perform your tasks. You can use the Applications menu and the Actions menu to access almost all of the standard applications, commands, and configuration options.

    You can also access almost all of the standard applications, commands, and configuration options from the Main Menu. You can access the items in the Applications and Actions menus from the Main Menu. You can add the Main Menu as a button to your panels.

  • Windows

    You can display many windows at the same time. You can run different applications in each window. The window manager provides frames and buttons for windows. The window manager enables you to perform standard actions such as move, close, and resize windows.

  • Workspaces

    You can subdivide your desktop environment into separate workspaces. A workspace is a discrete area in which you can work. You can specify the number of workspaces in your desktop environment. You can switch to a different workspace, but you can only display one workspace at a time.

  • Nautilus file manager

    The Nautilus file manager provides an integrated access point to your files and applications. You can display the contents of your files within a file manager window, or open the files in the appropriate application from the file manager. You can use the file manager to manage your files and folders.

  • Desktop

    The desktop is behind all of the other components on the desktop. The desktop is an active component of the user interface. You can place objects on the desktop to quickly access your files and directories, or to start applications that you use often. You can also right-click on the desktop to open a menu.

  • Start Here location

    The Start Here location provides an access point to some of the key features of the desktop environment. You can access your GNOME applications and configuration tools from the Start Here location. You can also access programs that enable you to configure your system as a server, and to choose other system settings.

  • Desktop environment preferences

    The desktop environment contains dedicated preference tools. Each tool controls a particular part of the behavior of the desktop environment. To start a preference tool, choose Applications->Desktop Preferences. Choose the item that you want to configure from the submenus.

The most powerful features of the desktop environment are the high degree of configurability and the multiple ways that you can perform tasks.

The desktop environment provides interoperability of the desktop environment components. Usually, you can perform the same action in several different ways. For example, you can start applications from panels, from menus, or from the desktop.

Your system administrator can make configuration changes to suit your needs, so that the desktop environment might not be exactly the same as described in this chapter. Nevertheless, this chapter provides a useful quick guide to how to work with the desktop environment.

Panels

You can add or delete panels at any time. When you start a session for the first time, the desktop environment usually contains a panel at the top edge of the screen, and a panel at the bottom edge of the screen.

You can perform the following actions with panels:

  • Create panels.

  • Delete panels.

  • Hide panels.

  • Add objects to panels.

  • Manipulate panel objects.

To Create Panels

To add a panel, right-click on a vacant space on any panel, then choose New Panel. The new panel is added to your desktop environment. The new panel contains no objects. You can customize the new panel to suit your preferences. You can add objects to the panel to fit your own requirements. You can also change the background of the panel.

Windows

You can display many windows at the same time in your desktop environment. Each window has a frame. The window frame contains active control elements that you can use to work with the window.

Types of Windows

The desktop environment features the following types of window:

  • Application windows

    When you run an application, a frame usually borders the window. The top edge of the application window contains a titlebar. The titlebar contains buttons that you can use to work with the window. The buttons in an application window frame enable you to perform actions such as open the Window Menu, or close the window. The Window Menu provides commands that you can perform on the window.

  • Dialog windows

    Dialog windows are associated with interactive processes. A dialog window consists of the window frame, and a single interactive pane that provides information and controls for the user. This manual refers to the interactive part of a dialog window as a dialog. The frame of a dialog window contains buttons that enable you to open the Window Menu, or to close the dialog window.

To Manipulate Windows

You use the frame of an application window or dialog window to perform various actions with the window. Most of the control elements are located on the top edge of the window frame. Figure 2.3 shows the top edge of a frame for a typical application window.

  • From the desktop

    Double-click on the Start Here object on the desktop. The contents of the Start Here location are displayed in a file manager window.

Desktop Environment Preferences

You can use desktop environment preference tools to configure almost every feature of the desktop environment. Each tool controls a particular part of the behavior of the desktop environment. For example, you can use a preference tool to select a theme for your desktop environment. A theme is a group of coordinated settings that specify the visual appearance of a part of your interface.

For convenience, the tools are grouped under the following headings:

  • Basic

  • Accessibility

  • Advanced

You can open your desktop environment preference tools in either of the following ways:

  • Choose Applications->Desktop Preferences. Choose the item that you require from the submenus.

  • Double-click on the Start Here object on the desktop. A Nautilus window opens at the Start Here location. Double-click on the Desktop Preferences object in the Nautilus window to display the preference tools. Double-click on the item that you require.

Applications

The applications that are provided with the GNOME Desktop share several characteristics. For example, the applications have a consistent look-and-feel. The applications share characteristics because the applications use the same programming libraries. An application that uses the standard GNOME programming libraries is called a GNOME-compliant application. For example, Nautilus and the gedit text editor are GNOME-compliant applications.

GNOME provides libraries in addition to the libraries provided by your operating system. The libraries enable GNOME to run your existing applications as well as GNOME-compliant applications. For example, if your operating system is UNIX-based, you can run your current X11 applications and Motif applications from the GNOME Desktop.

Some of the features of GNOME-compliant applications are as follows:

  • Consistent look-and-feel

    GNOME-compliant applications have a consistent look-and-feel. GNOME-compliant applications use the look-and-feel settings that you specify in the preference tools. You can use the following tools to change the look-and-feel of your GNOME-compliant applications:

    • Menus & Toolbars preference tool

    • Theme preference tool

  • Menubars, toolbars, and statusbars

    Most GNOME-compliant applications have a menubar, a toolbar, and a statusbar. The menubar always contains a File menu and a Help menu. The File menu always contains an Quit menu item, and the Help menu always contains an About menu item.

    A toolbar is a bar that appears under the menubar. A toolbar contains buttons for the most commonly-used commands. A statusbar is a bar at the bottom of a window that provides information about the current state of what you are viewing in the window. GNOME-compliant applications might also contains other bars. For example, Nautilus contains a location bar.

    Some of the bars in GNOME-compliant applications are detachable. That is, the bar has a handle that you can grab then drag the bar to another location. You can drag the bar to snap to another side of the window, or to another part of the screen. For example, you can detach the menubar, toolbar, and location bar in the file manager.

  • Default shortcut keys

    GNOME-compliant applications use the same shortcut keys to perform the same actions. For example, to quit a GNOME-compliant application, press Ctrl-Q. To undo an action in a GNOME-compliant application, press Ctrl-Z.

  • Drag-and-drop

    GNOME-compliant applications use the same protocol to implement drag-and-drop operations. Therefore, GNOME-compliant applications provide consistent feedback when you drag-and-drop items.

    The use of the same protocol also enables GNOME-compliant applications to interoperate in a sophisticated manner. For example, GNOME-compliant applications recognize the format of the items that you drag. When you drag a HTML file from a Nautilus window to a web browser, the file is displayed in HTML format in the browser. However, when you drag the HTML file to a text editor, the file is displayed in plain text format in the text editor.

To Find Out More

The desktop environment provides help if you want to find out more about the following areas:

  • Desktop environment topics

  • Applets

  • Applications

Chapter 3. GNOME Desktop Sessions

This chapter provides the information you need to start, manage, and end a GNOME Desktop session.

Starting a Session

A session occurs between the time that you log in to the desktop environment and the time that you log out. The login screen is your gateway to the desktop environment. The login screen provides fields for you to enter your username and password. The login screen enables you to select login options, for example you can select the language of your session.

You start a session when you log in. The session manager starts after your username and password are authenticated. The session manager enables you to manage the session. For example, you can save the state of your most recent session and return to that session the next time that you log in. The session manager saves and restores the following:

  • The appearance and behavior settings, for example fonts, colors, and mouse settings.

  • The applications that you were running, for example file manager and text editor windows. You cannot save and restore applications that the session manager does not manage. For example, if you start the vi editor from the command line in a terminal window, session manager cannot restore your editing session.

To Log in to a Session

To log in to a session, perform the following steps:

  1. On the login screen, click on the Session icon. Choose the GNOME Desktop from the list of available desktop environments.

  2. Enter your username in the Username field on the login screen, then press Return.

  3. Enter your password in the Password field on the login screen, then press Return.

When you log in successfully, the session manager starts a session. If this is the first time you log in, then the session manager starts a new session. If you have logged in before, then the session manager restores your previous session, if you saved your session settings when you logged out.

If you want to shut down or restart the system before you log in, click on the System icon on the login screen. A dialog is displayed. Select the option that you require, then click OK.

To Log in to a Session in a Different Language

To log in to a session in a different language, perform the following actions.

  1. On the login screen, click on the Language icon. Choose the language you require from the list of available languages.

  2. Enter your username in the Username field on the login screen, then press Return.

  3. Enter your password in the Password field on the login screen, then press Return.

When you lock your screen, the screensaver starts. To unlock the screen, move your mouse to display the locked screen dialog. Enter your username and password in the locked screen dialog, then press Return.

For information on configuring your screensaver, see Using the Basic Preference Tools.

Note

To lock your screen correctly, you must have a screensaver enabled.

Managing the Session

To configure the session management of the desktop environment, use the Sessions preference tool. The Sessions preference tool recognizes the following types of application:

  • Applications that are session-managed. When you save the settings for your session, the session manager saves all of the session-managed applications. If you log out, then log in again, the session manager automatically starts the session-managed applications.

  • Applications that are not session-managed. When you save the settings for your session, the session manager does not save any applications that are not session-managed. If you log out, then log in again, the session manager does not start non-session-managed applications. You must start the application manually. Alternatively, you can use the Sessions preference tool to specify non-session-managed applications that you want to automatically start.

Defining Session Behavior When You Log In and Log Out

To set how a session behaves when you log in and log out, use Sessions preference tool. Make the changes you require in the Session Options tabbed section. For example, you can select to display a splash screen when you log in.

To Use Startup Applications

You can configure your sessions to start with applications that are not session-managed. To configure non-session-managed startup applications, use the Sessions preference tool. Use the Startup Programs tabbed section to add, edit, and delete applications. If you save your settings and log out, the next time that you log in, the startup applications start automatically.

To Browse Applications in the Current Session

To browse the applications in the current session, use the Sessions preference tool. The Current Session tabbed section lists the following:

  • All GNOME applications that are currently running, that can connect to the session manager, and that can save the state of the application.

  • All preference tools that can connect to the session manager, and that can save the state of the tool.

You can use the Current Session tabbed section to perform a limited number of actions on the session properties of an application or preference tool. For example, you can edit the startup order, and restart style of any GNOME application or preference tool that is in the list.

To Save Session Settings

To save your session settings, perform the following steps:

  1. Configure your session to automatically save settings when you end the session. To configure your session, use the Sessions preference tool. The Sessions preference tool starts. Select the Automatically save changes to session option on the Session Options tabbed section.

  2. End your session.

If you do not select the Automatically save changes to session option, when you log out, a dialog asks if you want to save your current settings. To save your settings, select the option, then continue to log out.

Ending a Session

Log Out icon.

To end your session, close all your currently active processes, then perform one of the following actions:

  • Click on a Log Out button.

  • Choose Actions->Log Out.

  • Open the Main Menu, then choose Log Out.

Before you end a session, you might want to save your current settings so that you can restore the session later. During the logout process, a dialog asks if you want to save your current settings. In the Sessions preference tool, you can select an option to automatically save your current settings.

Chapter 4. Working With Panels

The information in this chapter describes how to use panels.

Introducing Panels

A panel is an area in your desktop environment from which you can run applications and applets, and perform other tasks. When you start a session for the first time, the desktop environment contains at least one panel. Your system administrator might have set your default panels according to your local requirements, so you might see slightly different default panels.

You can change the behavior and appearance of your panels to suit your requirements. You can also add or remove objects from your panels. You can create multiple panels, and choose different properties, objects, and backgrounds for each panel. You can also hide panels.

Typically, the GNOME Desktop contains a panel at the top edge of the screen, and a panel at the bottom edge of the screen. The following sections describe these panels.

Top Edge Panel

Figure 4.1 shows the panel at the top edge of the screen. Your system administrator might have set your default top edge panel according to your local requirements, so you might see a slightly different top edge panel.

Chapter 6. Working With Windows

The information in this chapter describes how to use windows in the desktop environment. You can use several types of window manager with the GNOME Desktop, for example, Metacity and Sawfish. Many of the functions in Metacity are also available in Sawfish. This chapter describes the functions that are associated with the Metacity window manager.

Windows and Workspaces

You can display many windows at the same time in your desktop environment. Your windows are displayed in subdivisions of your desktop environment that are called workspaces. A workspace is a discrete area in which you can work. Every workspace in your desktop environment contains the same desktop, the same panels, and the same menus. However, you can run different applications, and open different windows in each workspace. You can display only one workspace at a time in your desktop environment but you can have windows open in other workspaces.

The Workspace Switcher applet displays a visual representation of your windows and workspaces, as show in Figure 6.1.

Figure 6.1. Workspace Switcher Applet

Workspace Switcher applet. The context describes the graphic.

You can add workspaces at any time. To add workspaces to your desktop environment, right-click on the Workspace Switcher applet, then choose Preferences. The Workspace Switcher Preferences dialog is displayed. Use the Number of workspaces spin box to specify the number of workspaces you require.

Window Manager Behavior

A window manager controls how windows appear and behave. The window manager manages where your windows are located, and which window has focus. The window frame contains buttons that enable you to perform standard actions such as moving, closing, and resizing windows.

You can configure some window manager settings in the Windows preference tool. This manual describes the functions that are associated with the default configuration of the Metacity window manager. The default configuration is specified in the Windows preference tool.

Types of Window

The desktop environment features the following types of windows:

  • Application windows

    When you start an application, an application window opens. The window manager applies a frame to the application window. By default, the top edge of the application window contains a titlebar. The titlebar contains buttons that you can use to work with the window. The buttons in an application window frame enable you to perform actions such as open the Window Menu, or close the window. The Window Menu provides a number of actions that you can perform on the window.

    The following figure shows a typical application window.

    Application window in Simple theme.
  • Dialog windows

    A dialog window is a popup window in which you enter information or commands. The dialog appears within a window frame.

    You can use the top edge of the frame to work with the window. For example, you can use the titlebar to move the dialog. The frame also contains buttons that enable you to do the following:

    • Open the Window Menu

    • Close the dialog window

    Typically, you open a dialog window from an application window. When you open a dialog window, the window is usually raised and has focus. Some dialog windows do not allow you to use the application until you close the dialog.

    The following figure shows a typical dialog window.

    Dialog window in Simple theme.

Window Frames

A window frame is a border around a window. The window frame contains a titlebar. The titlebar contains buttons that you can use to work with the window.

Themes

You can apply several themes to your window frames. The theme determines how the frame looks. To choose a theme for all your window frames, choose Applications->Desktop Preferences->Theme.

Control Elements

You can use the window frame to perform various actions with the window. In particular, the titlebar contains various buttons. The following figure shows the titlebar of an application window:

Window titlebar. Callouts: Window Menu button, Titlebar, Minimize, Maximize, Close Window buttons.

Dialog windows also contain some of the window frame control elements. Table 6.1 describes the active control elements on window frames, from left to right.

  • The middle section contains options that enable you to sort your files automatically.

  • The bottom section contains options that enable you to modify how your files are arranged.

Choose the appropriate options from the submenu, as described in the following table:

Option

Description

Manually

Select this option to arrange the items manually. To arrange the items manually, drag the items to the location you require within the view pane.

By Name

Select this option to sort the items alphabetically by name. The order of the items is not case sensitive. If the file manager is set to display hidden files, the hidden files are shown last.

By Size

Select this option to sort the items by size, with the largest item first. When you sort items by size, the folders are sorted by the number of items in the folder. The folders are not sorted by the total size of the items in the folder.

By Type

Select this option to sort the items alphabetically by object type. The items are sorted alphabetically by the description of their MIME type in the File Types and Programs preference tool. The MIME type identifies the format of a file, and enables applications to read the file. For example, an email application can use the image/png MIME type to detect that a PNG file is attached to an email.

By Modification Date

Select this option to sort the items by the date the items were last modified. The most recently modified item is first.

By Emblems

Select this option to sort the items by any emblems that are added to the items. The items are sorted alphabetically by emblem name. Items that do not have emblems are last.

Compact Layout

Select this option to arrange the items so that the items are closer to each other.

Reversed Order

Select this option to reverse the order of the option by which you sort the items. For example, if you sort the items by name, select the Reversed Order option to sort the items in reverse alphabetical order.

The file manager remembers how you arrange the items in a particular folder. The next time that you display the folder, the items are arranged in the way that you selected. In other words, when you specify how to arrange the items in a folder, you customize the folder to display the items in that way. To return the arrangement settings of the folder to the default arrangement settings specified in your preferences, choose View->Reset View to Defaults.

To Resize an Icon in Icon View

In icon view, you can change the size of the icon that represents an item that is displayed. To change the size of an item in icon view, perform the following steps:
