108 Part I . Linux First Steps Using the Nautilus File Manager At one time, file managers did little more than let you run applications, create data files, and open folders. These days, as the information a user needs expands beyond the local system, file managers are expected to also display Web pages, access FTP sites, and play multimedia content. The Nautilus file manager, which is the default GNOME file manager, is an example of just such a file manager. When you open the Nautilus file manager window (from the GNOME main menu or by opening the Home icon or other folder on your desktop), you see the name of the location you are viewing (such as the folder name) and what that location contains (files, folders, and applications). Figure 3-11 is an example of the file manager window displaying the home directory of a user named chris (/home/chris). Figure 3-11: The Nautilus file manager enables you to move around the file system, open directories, launch applications, and open Samba folders. In GNOME 2.8, the default Nautilus window has been greatly simplified to show fewer controls and provide more space for file and directory icons. Double-click a folder to open that folder in a new window. Select your folder name in the lower-left corner of the window to see the file system hierarchy above the current folder (as shown in Figure 3-11). Whatever size, location, and other setting you had for the folder the last time you closed it, GNOME remembers and returns it to that state the next time you open it. To see more controls, right-click a folder and select Browse Folder to open it. Icons on the toolbar of the Nautilus window let you move forward and back among the directories and Web sites you visit. To move up the directory structure, click the up arrow. To refresh the view of the folder or Web page, click the Reload button. The Home button takes you to your home page, and the Computer button lets you see the same type of information you would see from a My Computer icon on a Windows system (CD drive, floppy drive, hard disk file systems, and network folders).

Chapter 3 . Getting into the Desktop 107 Figure 3-10 shows a portion of the panel with an open drawer that includes icons for launching a Terminal window, the GIMP, and the Ethereal window. Figure 3-10: Add launchers or applets to a drawer on your GNOME panel. Changing Panel Properties Panel properties you can change are limited to the orientation, size, hiding policy, and background. To open the Panel Properties window that applies to a specific panel, right-click on an open space on the panel and choose Properties. The Panel Properties window that appears includes the following values: . Name Contains a name by which you identify this panel. . Orientation Move the panel to different locations on the screen by clicking on a new position. . Size Select the size of your panel by choosing its height in pixels (48 pixels by default). . Expand Click this check box to have the panel expand to fill the entire side, or unselect the check box to make the panel only as wide as the applets it contains. . AutoHide Select whether a panel is automatically hidden (appearing only when the mouse pointer is in the area). . Show Hide buttons Choose whether the Hide/Unhide buttons (with pixmap arrows on them) appear on the edges of the panel. . Arrows on hide buttons If you select Show Hide Buttons, you can choose to have arrows on those buttons. . Background From the Background tab, you can assign a color to the background of the panel, assign a pixmap image, or just leave the default (which is based on the current system theme). Click the Background Image check box if you want to select an Image for the background, and then select an image, such as a tile from /usr/share/backgrounds/tiles or other directory. I usually turn on the AutoHide feature and turn off the Hide buttons. Using AutoHide gives you more desktop space to work with. When you move your mouse to the edge where the panel is, the panel pops up so you don t need Hide buttons. Tip

106 Part I . Linux First Steps If the application you want to launch is not on your red hat menu, you can build a launcher yourself as follows: 1. Right-click in an open space on the panel. 2. Select Add to Panel.Custom Application Launcher.Add. The Create Launcher window appears. 3. Provide the following information for the application that you want to add: Name A name to identify the application (this appears in the tool tip when your mouse is over the icon). Generic Name A name to identify the type of application. Comment A comment describing the application. It also appears when you later move your mouse over the launcher. Command The command line that is run when the application is launched. Use the full path name, plus any required options. Type Select Application (to launch an application). (Other selections include Link, to open a Web address in a browser, or FSDevice, to open a file system.) Run in Terminal Click this box if the application is a character-based or ncurses application. (Applications written using the curses library run in a Terminal window but offer screen-oriented mouse and keyboard controls.) 4. Click the Icon box (it might say No Icon). Select one of the icons shown and click OK. Alternatively, you can browse the Linux file system to choose an icon. Icons available to represent your application are contained in the /usr/share/ pixmaps directory. These icons are either in .png or .xpm formats. If there isn t an icon in the directory you want to use, create your own (in one of those two formats) and assign it to the application. 5. Click OK. The application should now appear in the panel. Click it to start the application. Adding a Drawer A drawer is an icon that you can click to display other icons representing menus, applets, and launchers; it behaves just like a panel. Essentially any item you can add to a panel you can add to a drawer. By adding a drawer to your GNOME panel, you can include several applets and launchers that together take up only the space of one icon. Click on the drawer to show the applets and launchers as though they were being pulled out of a drawer icon on the panel. To add a drawer to your panel, right-click the panel and select Add to Panel.Drawer. A drawer appears on the panel. Right-click it, and add applets or launchers to it as you would to a panel. Click the icon again to retract the drawer. Note

Chapter 3 . Getting into the Desktop 105 After an applet is installed, right-click it on the panel to see what options are available. For example, select Preferences for the stock ticker, and you can add or delete stocks whose prices you want to monitor. If you don t like the applet s location, right-click it, click Move, slide the mouse until the applet is where you want it (even to another panel), and click to set its location. If you no longer want an applet to appear on the panel, right-click it, and then click Remove From Panel. The icon representing the applet disappears. If you find that you have run out of room on your panel, you can add a new panel to another part of the screen, as described in the next section. Adding Another Panel You can have several panels on your GNOME desktop. You can add panels that run along the entire bottom, top, or side of the screen. To add a panel, do the following: 1. Right-click an open space in the panel so that the Panel menu appears. 2. Select New Panel. A new panel appears at the top of the screen. 3. Right-click an open space in the new panel and select Properties. 4. From the Panel Properties, select where you want the panel from the Orientation box (Top, Bottom, Left or Right). After you ve added a panel, you can add applets or application launchers to it as you did to the default panel. To remove a panel, right-click it and select Delete This Panel. Adding an Application Launcher Icons on your panel represent a Web browser and several office productivity applications. You can add your own icons to launch applications from the panel as well. To add a new application launcher to the panel, do the following: 1. Right-click in an open space on the panel. 2. Select Add to Panel.Application Launcher from the menu. All application categories from your main desktop menu (the one under the red hat or footprint icon) appear. 3. Select the arrow next to the category of application you want, and then select Add. An icon representing the application appears. To launch the application you just added, simply click the icon on the panel.

104 Part I . Linux First Steps The following sections describe some things you can do with the GNOME panel. Use the Main Menu Click the main menu icon on the panel, and you see categories of applications and system tools that you can select. Click the application you want to launch. To add an item to launch from the panel and to view its properties right-click it. There is currently no way to add or remove applications to or from this menu from the GUI in GNOME. However, you can manually add items to your GNOME menus. To add to the main menu, create a .desktop file in the /usr/share/applications directory. The easiest way to do that is to copy an existing .desktop file that is on the menu you want and modify it. For example, to add a video player to the Sound & Video menu, you could do the following (as root user): # cd /usr/share/applications # cp gnome-cd.desktop vidplay.desktop Next use any text editor to change the contents of the vidplay.desktop file you created by adding a comment, file to execute, icon to display, and application name. After you save the changes, the new item immediately appears on the menu (no need to restart anything). Adding an Applet There are several small applications, called applets, that you can run directly on the GNOME panel. These applications can show information you may want to see on an ongoing basis or may just provide some amusement. To see what applets are available and to add applets that you want to your panel, perform the following steps: 1. Right-click an open space in the panel so that the panel menu appears. 2. Select Add to Panel. An Add to Panel window appears. 3. Select from among several dozen applets, including a clock, dictionary lookup, stock ticker, weather report, lock screen, log out, run application, take screen shot, fortune-telling fish, eyes that follow your mouse, e-mail Inbox monitor, and modem lights monitor. The applet appears on the panel, ready for you to use. Figure 3-9 shows (from left to right) eyes, system monitor, CD player, stock ticker, e-mail Inbox monitor, and dictionary lookup applets. Figure 3-9: Placing applets on the Panel makes it easy to access them.

Chapter 3 . Getting into the Desktop 103 From the gconf-editor window, select apps.metacity, and then choose from general, global_keybindings, keybindings_commands, window_keybindings, and workspace_names. Click each key to see its value, along with short and long descriptions of the key. Using the GNOME panel The GNOME panel is the place from which you manage your desktop. From this panel you can start applications (from buttons or menus), see what programs are active, and monitor how your system is running. There are also many ways to change the panel by adding applications or monitors, or by changing the placement or behavior of the panel, for example. Right-click any open space on the panel to see the Panel menu (see Figure 3-8). Figure 3-8: The GNOME panel menu. From GNOME s Panel menu, you can perform a variety of functions, including: . Use the main menu. The main menu (represented by a red hat in Red Hat systems) displays most of the applications and system tools you will use from the desktop. . Add to panel. Add an applet, menu, launcher, drawer, or button. . Delete this panel. Delete the current panel. . Properties. Change the panel s position, size, and background properties. . New panel. Add panels to your desktop in different styles and locations. You can also work with items on a panel. For example, you can: . Move items. Move items on a panel simply by dragging and dropping them to new positions. . Resize items. Some elements, such as the Window List, can be resized by clicking an edge and dragging it to the new size. . Use the Window List. Tasks running on the desktop appear in the Window List area. Click a task to minimize or maximize it.

Choose current workspace Four virtual workspaces appear in the workspace switcher. Click any of the four virtual workspaces to make it your current workspace. . Move windows to other workspaces Click any window, each represented by a tiny rectangle in a workspace, to drag-and-drop it to another workspace. . Add more workspaces Right-click the workspace switcher, and select Preferences. You can add workspaces (up to 32). . Name workspaces Right-click the workspace switcher and select Preferences. Click in the Workspaces pane to change names of workspaces to any names you choose. You can view and change information about Metacity controls and settings using the gconf-editor window (type gconf-editor from a Terminal window). As the window says, it is not the recommended way of changing preferences, so when possible, you should change the desktop through GNOME preferences. However, gconf-editor is a good way to see descriptions of each Metacity feature.

Chapter 3 . Getting into the Desktop 101 Figure 3-7: In the GNOME desktop environment, you can manage applications from the panel. There really isn t much you can do with Metacity (except get your work done efficiently). Assigning new themes to Metacity and changing colors and window decorations is done through the GNOME preferences (and is described later). A few Metacity themes exist, but expect the number to grow. Basic Metacity functions that might interest you are keyboard shortcuts and the workspace switcher. Table 3-3 shows keyboard shortcuts to get around the Metacity window manager.

100 Part I . Linux First Steps preferences. To use your GNOME desktop, you should become familiar with the following components: . Metacity (window manager) The default window manager for GNOME in Fedora is Metacity. It provides such things as themes, and window borders and controls. . Nautilus (file manager/graphical shell) When you open a folder (by double-clicking the Home icon on your desktop, for example), the Nautilus window opens and displays the contents of the selected folder. Nautilus can also display other types of content, such as shared folders from Windows computers on the network (using SMB). . GNOME panel (application/task launcher) This panel, which lines the bottom of your screen, is designed to make it convenient for you to launch the applications you use, manage running applications, and work with multiple virtual desktops. By default, the panel contains the main menu (represented by a red hat in Red Hat Linux or a footprint icon in others), desktop application launchers (Evolution e-mail and a set of OpenOffice.org applications), a workspace switcher (for managing four virtual desktops), window list, and a clock. It also has an icon to alert you when you need software updates. . Desktop area The windows and icons you use are arranged on the desktop area, which supports such things a drag-and-drop between applications, a desktop menu (right-click to see it), and icons for launching applications. There is a Computer icon which consolidates CD drives, floppy drives, the file system, and shared network resources in one place. GNOME also includes a set of Preferences windows that enable you to configure different aspects of your desktop. You can change backgrounds, colors, fonts, keyboard shortcuts, and other features relating to the look and behavior of the desktop. Figure 3-7 shows how the GNOME desktop environment appears the first time you log in, with a few windows added to the screen. The following sections provide details on using the GNOME desktop. Using the Metacity Window Manager The Metacity window manager seems to have been chosen as the default window manager for GNOME in Red Hat Linux because of its simplicity. The creator of Metacity refers to it as a boring window manager for the adult in you then goes on to compare other window managers to colorful, sugary cereal, while Metacity is characterized as Cheerios.

An icon representing the application immediately appears on the panel. (If the panel seems a bit crowded, you might want to remove some applications you don t use.) If you decide later that you no longer want this application to be available on the panel, right-click the edge of the icon and click the Remove button. To move it to a different location on the panel, right-click it, click Move, move it to where you want it on the panel, and click again. Adding Applications to the Desktop To add an application to the desktop, use the desktop menu. Here s how: 1. Right-click an open area of the desktop. 2. Select Create New.File.Link to Application from the menu. 3. On the Properties window that appears, click the General tab and replace Link to Application with the name you want to appear for the application on the desktop. On that same tab, click the gear icon and select one icon from the list to represent your application. 4. Click the Application tab and add a description of the application and a comment. Then in the Command box, type the command you want to run or browse your file system (click the Browse button) to find the command to run. 5. Click OK, and the icon for the new application launcher appears on the desktop. If you decide later that you no longer want this application to be available on the desktop, right-click the icon and click Delete or Move to Trash. The GNOME Desktop GNOME (pronounced guh-nome) provides the desktop environment that you get by default when you install Fedora Core and other Red Hat Linux systems. This desktop environment provides the software that is between your X Window System framework and the look-and-feel provided by the window manager. GNOME is a stable and reliable desktop environment, with a few cool features in it. The new GNOME 2.8 desktop comes with the most recent version of Fedora Core. For GNOME 2.8, enhancements include a new volume manager (for managing removable media), keyring manager (for managing keys), and remote desktop
