The workspace switcher

Using the workspace switcher, you can have multiple desktops (up to 36, in fact), each displaying different programs and windows. Each workspace is represented by an icon showing where the various windows are located within it. To switch between them, you can Click the icon representing the workspace you wish to access. Use the keyboard shortcut alternatives of Ctrl-Alt-Left arrow to select the workspace to the left or Ctrl-Alt-Right arrow to select the one to the right. When you do this, a...

PiTiVi Video Editor

When it comes to video editing, Ubuntu also comes up with the goods, and one of the best applications is the PiTiVi program, which is not installed by default (but see the section What's New in 10.04 on page 396). However, you can easily install it by entering pitivi into the search field of the Ubuntu Software Center. I have found that the best way to use the program is to drag and drop all the source files (which can be movies, audio, and still images) into the lefthand frame. From there you...

Rhythmbox Music Player

You can open Rhythmbox by selecting it from the Applications Sound & Video menu. It may not immediately open a window, though instead, a new icon (looking like a loudspeaker cabinet with one large and either one or two small speakers depending on the version) will be placed on the top status bar, as shown in Figure 14-5. Figure 14-5. Rhythmbox is the icon that looks like a speaker cabinet To open the program, click the icon, and a window like the one in Figure 14-6 will appear, although if...

Using Pipes

A little earlier we looked at alternative ways of using the more and grep commands by piping output through them using the operator. Pipes are such a useful device that you will see them used in a variety of ways, often with multiple commands piped together to produce a final output. For example, take a look at the following composite command The ps program, in conjunction with the argument -ax, displays all the background processes running on your computer, and is covered in more detail in the...

Browsers and Email Clients

I sometimes worry that Linux users may be a little too complacent about the robustness of their operating system so that should an exploit be discovered and a virus spread, they will be less prepared than Windows users to deal with it. Fortunately, browser exploits and email attachment malware mostly affect Windows users, and therefore the programs they try to install on a Linux computer will fail. But you must still be cautious about what you download, as you never know whether someone will...

Configuration Editor

This is an editor available for modifying various GNOME settings, which works in much the same way as editing a Windows registry. Most of the settings available are quite advanced, and it's possible to mess up programs, even GNOME itself, if you make the wrong changes. However, there are some benign uses for the program, such as specifying the icons that should or should not display on the desktop. To run the editor, press Alt-F2, enter gconf-editor into the input field that pops up, and click...

Using Search to Install a Program

Instead of browsing through the Synaptic categories, you can use the Quick Search input box. So, in the preceding example, just type chess into the box, and it will narrow down the packages displayed in the top-righthand pane to those whose filenames or descriptions match that word. There will probably be many alternatives in the list, or some specialized programs that add extra functionality. You probably won't want all the items displayed, so just mark the packages you want, and then apply...

The Applications Menu

The Applications menu (see Figure 4-7) contains the main programs and accessories you use. This includes things such as Calculator, CD DVD Creator, and Terminal under the Accessories subheading over a dozen games under Games the GIMP image editor and F-Spot Photo Manager under Graphics the Firefox web browser and Empathy instant messenger (IM) program under Internet Dictionary and the OpenOffice.org applications under Office and Sound Recorder, Brasero Disc Burner, and Movie Player under Sound...

The Trash

Whenever you wish to delete a file, just drag and drop it into the Trash and it will be deleted. But there's a failsafe to prevent you from accidentally deleting files you didn't mean to erased files are stored in the Trash until you empty it by right-clicking the icon and selecting Empty Trash. To restore or undelete a file, click the Trash icon and a window will open up displaying its contents (see Figure 4-26). You can then drag and drop the files shown to other places in the computer's...

Other File Attributes

As if all that weren't enough, a number of other file attributes are available to you. To view them, right-click on a file and select Properties to bring up a window such as the Figure 5-8. Creating the new group Internet one shown in Figure 5-9. Here, you can see a number of tabs, which vary according to the file type or folder selected. The tabs provide even more control over what you can do with your files and how they are displayed, and include the following Lists basic details about a file...

Movie Player

The Movie Player program is supplied with Ubuntu as the default application for playing movies and audio files. You can open it from the Applications Sound & Video menu, or by default, it will be called up when you double-click a movie or audio file. Figure 14-1 shows the program displaying the file water-and-wind.ogv, one of the samples in the folder usr share example-content (which you may also have copied to your desktop if you followed the examples in Chapter 12). To view a movie in...

Installing Ubuntu As a Standalone OS

There are two ways you can go about natively installing Ubuntu. The first is to run the Live DVD and then double-click the Install Ubuntu 9.10 icon on the desktop (see Figure 2-8) to start a six-screen setup process, which begins with choosing the installation language. Alternatively, when you reboot your computer, simply select the Install Ubuntu option. Either way, the installation screens will be similar to those starting at Figure 2-28. Applications Places System -ff < ij El Tue Nov 3,12...

The Ubuntu Software

When you call up the Software Sources window, you must first enter your password. Then you'll see a selection of five tabs, the first of which is Ubuntu Software. Under this tab, there are several checkboxes and a drop-down input, with which you can specify the types of software to display, as follows. Canonical-supported and community-maintained software Canonical-supported software is maintained by the programmers at Canonical, the company that publishes Ubuntu. Community-maintained software...

Installing and Upgrading Ubuntu

In this chapter, we'll take a look at the companion DVD for this book, which is attached to the inside back cover, and I'll also show readers without access to the DVD how to get the same software by downloading and burning ISO disc images. Unlike most program discs you may have used, this DVD is unusual in that you don't actually have to install anything if you don't wish to, because it's been set up as a Live This means that the DVD itself is a fully working installation of Ubuntu 9.10 that...

The Synaptic Package Manager

The predecessor to the Ubuntu Software Center is the Synaptic Package Manager, which you can call up by selecting System Administration Synaptic Package Manager. After entering your password, you'll see a new window similar to Figure 8-14. 11832 packages listed, 1640 installed, 0 broken, 0 to install upgrade, 0 to remove Figure 8-14. The Synaptic Package Manager main screen Figure 8-14. The Synaptic Package Manager main screen You might need to use Synaptic because the Software Center is...

Audacity Audio Editor

Audacity is a multitrack digital audio editing application. It's not bundled with Ubuntu, but you can easily install it by entering audacity in the search field of the Ubuntu Software Center. Once installed, it will be available in the Applications Sound & Video menu. You can also open it by right-clicking an audio file and selecting Open With Audacity, which is exactly what has been done in Figure 14-10 using the file InTheCircle.oga, one of the supplied example media files. File Edit View...

Preferences

The place to find most of your maintenance and administration tasks is in the System Preferences menu (see Figure 9-1). Some of these programs offer fairly advanced options that you most likely won't need, but there are half a dozen of them with which you should acquaint yourself. I'll run through these programs in the order in which they appear in the menu. Power Management This program is useful for extending the product life of the components used by your PC, by giving you the ability to...

The Command Line Editor

Before looking at the command-line instructions, I'd like to explore the various ways you can enter and edit text on the command line, because numerous options are available to make your life a lot easier. For example, once you have entered one or more commands, you can scroll back and forth through the command history to reselect or edit previous commands by using the Up and Down cursor keys, or Ctrl-N for Next and Ctrl-P for Previous, as you can see from Table 7-1. Move the cursor to the...

The find Command

There are thousands of files in an Ubuntu installation (if not hundreds of thousands), so locating individual ones could be a nightmare without the find command. But with it, you can find almost any file within a few seconds. The program supports many options, but at its most basic you use it by entering a command such as this find -name blackjack This command searches the entire filesystem for any files called blackjack. However, as you will see from Figure 7-4, folders that you do not have...

Administration

Moving on to the Administration menu next, there are several more maintenance options you may need. The Computer Janitor helps you remove old files that are no longer needed. When you select it, you will be prompted for your password, and then a screen such as the one in Figure 9-11 will be displayed. ffl I nux-image-2.6.28-15-generic xul runner- 1.9-gnome-support setti ngs. conf. dpkg-ol d 0 etc ca-certificates.conf.dpkg-old In the lefthand frame, you can see that two old packages have been...
