Chapter 3 . Getting into the Desktop 111 The following items highlight some of the preferences you might want to change: . Accessibility If you have difficulty operating a mouse or keyboard, the Keyboard Accessibility Preferences (AccessX) window lets you adapt mouse and keyboard settings to make it easier for you to operate your computer. From the Preferences window, open Accessibility. . Desktop Background From Desktop Background Preferences, you can choose a solid color or an image to use as wallpaper. If you choose to use a solid color (by selecting No Wallpaper), click the Color box, select a color from the palette, and click OK. To use wallpaper for your background, open the folder containing the image you want to use, and then drag the image into the Desktop Wallpaper pane on the Desktop Preferences window. You can choose from a variety of images in the /usr/share/nautilus/patterns and /usr/share/backgrounds/tiles directories. Then choose to have the wallpaper image tiled (repeated pattern), centered, scaled (in proportion), or stretched (using any proportion to fill the screen). . CD and DVD Properties Even if you don t change CD properties, it is important to know what happens when you insert a CD or DVD. (These properties are associated with a feature called magicdev, which is a bit controversial. You ll learn more about magicdev in Chapter 19.) For data CDs, the CD is mounted when it is inserted, any autorun program on the CD is run, and a file manager window opens for the CD. If you would rather mount and open the CD as you choose, you can turn off any or all of these preferences. For audio CDs, the gnome-cd player is launched and the CD begins playing. You can type in a different CD player, if you like, or clear the Run Command When CD Is Inserted check box so that you can choose which player to use later. For blank CDs, a CD-burning utility is launched through the Nautilus window. After that, you can burn audio files or data to the blank CD. For DVD (video), the DVD is not set to play automatically. If you have a player installed that can play the content of DVDs that you have, turn on this feature and add the command to run the player into the Command box. For a data DVD, such as the one that comes with this book, you can simply mount it to access the data. . File Types and Programs The File Types and Programs preferences can help you understand the different types of data files that GNOME knows about. Double-click this icon to see data types (audio, documents, images, information, and so on) that have definitions in GNOME. Then choose a particular data type (such as Audio, ogg audio). From the Edit File Type window that appears, you can see the information assigned to the file type. For example, when data that ends with an .ogg
