97Chapter 3Getting into the DesktopChanging the DisplayYou can change a lot of the look-and-feel of your desktop display. Under theAppearance & Themes topic (click the plus sign), you can change Background, Colors, Fonts, Icons, Launch Feedback, Panel, Screen Saver, Style, Theme Manager, and Window Decoration. Here are a few of the desktop features you may want to change: .Background Under the Appearance & Themes heading in the KDE ControlCenter, select Background. By default, all of your virtual desktops use thesame background. To have different backgrounds for each virtual desktop, select the box next to the Setting for Desktop heading, choose any of the fourdesktops, and then choose the background you want for the current desktop. For each desktop, select Picture, Slideshow, or No Picture. For a Picture, thereare several backgrounds you can choose from the pull-down menu, or you canbrowse your file system for a picture. To do a slide show, click Slideshow andselect Setup (to choose your pictures and define how often they change). Click Apply to apply your selections. .Screensaver Under the Appearance & Themes heading, select Screen Saver. From the window that appears, select from a list of screen savers. KNOPPIXonly includes a blank screen saver. However, Fedora Core comes with about160 different screen savers. My favorite is Slideshow, where you can have aslide show of images for your screen saver. Click Setup to identify an imagedirectory or otherwise modify the behavior of the screen saver. Under set- tings, select how many minutes of inactivity before the screen saver turns on. You can also choose Require Password to require that a password be enteredbefore you can access your display after the screen saver has come on. If you are working in a place where you want your desktop to be secure, be sureto turn on the Require Password feature. This prevents others from gaining accessto your computer when you forget to lock it or shut it off. If you have any virtualterminals open, switch to them and type vlockto lock each of them as well. (Youneed to install the vlock package if the vlockcommand isn t available.) .Fonts You can assign different fonts to different places in which fontsappear on the desktop. Under the Appearance & Themes heading, selectFonts. Select one of the categories of fonts (General, Fixed width, Toolbar, Menu, Window title, Taskbar, and Desktop fonts). Then click the Choose checkbox to select a font from the Select Font list box that you want to assign tothat category. If the font is available, an example of the text appears in theSample text box. To use 100dpi fonts, you need to add an entry for 100dpi fonts to /etc/X11/ xorg.conffile. After you make that change, you need to restart the X server for itto take effect. TipTip08_

96Part ILinux First StepsUsing Virtual DesktopsTo give you more space to run applications than will fit on your physical screen, KDE gives you access to several virtual desktops at the same time. Using the 1, 2, 3, and 4 buttons on the panel, you can easily move between the different desktops. Just click the one you want. If you want to move an application from one desktop to another, you can do so fromthe window menu. Click the window menu button for the window you want tomove, click To Desktop, and then select Desktop 1, 2, 3, or 4. The window willdisappear from the current desktop and move to the one you selected. Configuring the DesktopIf you want to change the look, feel, or behavior of your KDE desktop, the bestplaceto start is the KDE Control Center. The Control Center window (Figure 3-6) lets you configure dozens of attributes associated with colors, fonts, backgrounds, and screen savers. You can also change attributes relating to how you work withwindows and files. To open the KDE Control Center from the desktop, select Settings.Control Centerfrom the K menu or open a Terminal window and type sudo kcontrol. Figure 3-6:Manage your KDE desktop from the KDE Control Center. Click the plus (+) sign next to the topic you want to configure, and then select theparticular item you want to configure. The following sections describe some of thefeatures you can configure from the Control Center.

95Chapter 3Getting into the DesktopUncluttering the DesktopIf your windows are scattered willy-nilly all over the desktop, here are a couple ofways you can make your desktop s appearance a little neater: .Unclutter windows Right-click the desktop, and then click Windows. Unclutter Windows on the menu. All windows that are currently displayed onthe desktop are lined up along the left side of the screen (or aligned withother windows), from the top down. .Cascade windows Right-click the desktop, and then click Windows. Cascade windows on the menu. The windows are aligned as they are with theUnclutter selection, except that the windows are each indented starting fromthe upper-left corner. Moving WindowsThe easiest way to move a window from one location to another is to place the cur- sor on the window s title bar, hold down the mouse button and drag the window toa new location, and release the mouse button to drop the window. Another way todo it is to click the window menu button (top-left corner of the title bar), selectMove, move the mouse to relocate the window, and then click again to place it. If somehow the window gets stuck in a location where the title bar is off the screen, you can move it back to where you want it by holding down the Alt key and clickingthe left mouse button in the inner window. Then move the window where you wantit and release. Resizing WindowsTo resize a window, grab anywhere on the outer edge of the window border, and thenmove the mouse until the window is the size you want. Grab a corner to resize verti- cally and horizontally at the same time. Grab a side to resize in only one direction. You can also resize a window by clicking the window menu button (top-left cornerof the title bar) and selecting Size. Move the mouse until the window is resized andclick to leave it there. Pinning Windows on Top or BottomYou can set a window to always stay on top of all other windows or always stayunder them. Keeping a window on top can be useful for a small window that youwant to always refer to (such as a clock or a small TV viewing window). To pin awindow on top of the desktop, click in the window title bar. From the menu thatappears, select Advanced.Keep Above Others. Likewise, to keep the window onthe bottom, select Advanced.Keep Below Others.

94Part ILinux First StepsCreating an Image Gallery with KonquerorThere s a neat feature in Konqueror that lets you create a quick image gallery. The featuretakes a directory of images, creates thumbnails for each one, and generates an HTML (Web) page. The HTML page includes a title you choose, all image thumbnails arranged on a page, and links to the larger images. Here s how you do it: 1.Add images you want in your gallery to any folder (for example, /home/jake/images). Make sure they are sized, rotated, and cropped the way you like before beginning. (TryThe Gimp for manipulating your images by typing gimp&from a Terminal.) 2.Open the folder in Konqueror (for example, type /home/knoppix/imagesin theLocation box). 3.Click Tools.Create Image Gallery. The Create Image Gallery window appears. 4.Type a title for the image gallery into the Page Title box. You can also select otherattributes of the gallery, such as the number of rows, information about the imageto appear on the page (name, size, and dimension), the fonts, and the colors to use. 5.Click OK. Konqueror generates the thumbnails and adds them to the thumbs directory. The imagegallery page itself opens and is saved to the images.htmlfile. (Select the Folders button tosave the gallery under a different name. You can also have Konqueror create galleries inrecursive subfolders to a depth you choose.) You can now copy the entire contents of thisdirectory to a Web server and publish your pictures on the Internet. Here s an example of aKonqueror image gallery:

93Chapter 3Getting into the Desktop .Crypto Display a list of secure certificates that can be accepted by theKonqueror browser. By default, Secure Socket Layer (SSL) versions 2 and 3 cer- tificates are accepted, as is TLS support (if supported by the server). You canalso choose to be notified when you are entering or leaving a secure Web site. .Browser Identification Set how Konqueror identifies itself when it accessesa Web site. By default, Konqueror tells the Web site that it is the Mozilla Webbrowser. You can select Konqueror to appear as different Web browsers tospecific sites. You must sometimes do this when a site denies you accessbecause you do not have a specific type of browser (even though Konquerormay be fully capable of displaying the content). .Plugins Display a list of directories that Konqueror will search to find plug- ins. Konqueror can also scan your computer to find plug-ins that are installedfor other browsers in other locations. .Performance Display configuration settings that can be used to improveKonqueror performance. You can preload an instance after KDE startup orminimize memory usage. Managing WindowsIf you have a lot of windows open at the same time, tips for organizing and manag- ing the windows on your desktop are very helpful. KDE helps you out by maintain- ing window lists you can work with and shortcuts for keeping the windows inorder. Using the TaskbarWhen you open a window, a button representing the window appears in the taskbarat the bottom of the screen. Here is how you can manage windows from thetaskbar: .Toggle windows Left-click any running task in the taskbar to togglebetween opening the window and minimizing it. .Move windows Move a window from the current desktop to any other vir- tual desktop. Right-click any task in the taskbar, select To Desktop, and thenselect any desktop number. The window moves to that desktop. All the windows that are running, regardless of which virtual desktop you are on, appear in the taskbar. If there are multiple windows of the same type shown as asingle task, you can right-click that task; then, select All to Desktop to move allrelated windows to the desktop you pick.

92Part ILinux First Steps .File Associations Describes which programs to launch for each file type. .Web Behavior Click the Behavior (Browser) button to open a window to con- figure the Web browser features of Konqueror. By enabling Form Completion, Konqueror can save form data you type and, at a later time, fill that informationinto other forms. If your computer has limited resources, you can speed uppage display by clearing the Automatically Load Images check box or by dis- abling animations. .Java and JavaScript Enable or disable Java and JavaScript content con- tained in Web pages in your Konqueror window. .Fonts Choose which fonts to use, by default, for various fonts needed onWeb pages (standard font, fixed font, serif font, sans serif font, cursive font, and fantasy font). The serif fonts are typically used in body text, while sansserif fonts are often used in headlines. You can also set the Minimum andMedium font sizes. .Web Shortcuts Display a list of keyword shortcuts you can use to go to dif- ferent Internet sites. For example, follow the word ask with a search stringto search the Ask Jeeves (www.ask.com) Web site. (This feature doesn tappear to be working at the moment.) .History Sidebar Modify the behavior of the list of sites you have visited(the history). By default, the most recent 500 URLs are stored, and after 500days (KNOPPIX) or 90 days (Fedora), a URL is dropped from the list. There salso a button to clear your history. (To view your history list in Konqueror, open the left side panel, then click the tiny scroll icon.) .Cookies Choose whether cookies are enabled in Konqueror. By default, youare asked to confirm that it is okay each time a Web site tries to create ormodify a cookie. You can change that to either accept or reject all cookies. You can also set policies for acceptance or rejection of cookies based on hostand domain names. .Cache Indicate how much space on your hard disk can be used to store thesites you have visited (based on the value in the Disk Cache Size field). .Proxy Click Proxy to configure Konqueror to access the Internet through aproxy server (by default, Konqueror tries to connect there directly). You needto enter the address and port number of the computer providing HTTP and/orFTP proxy services. Alternatively, you can have Konqueror try to automati- cally detect the proxy configuration. .Stylesheets Choose whether to use the default stylesheet, a user-definedstylesheet, or a custom stylesheet. The stylesheet sets the font family, fontsizes, and colors that are applied to Web pages. (This won t change particularfont requests made by the Web page.) If you select a custom stylesheet, clickthe Customize tab to customize your own fonts and colors.

91Chapter 3Getting into the DesktopUsing Other Browser FeaturesBecause Konqueror performs like a Web browser as well as a file manager, it includesseveral other browser features. For example, the bookmarks feature enables you tokeep a bookmark list of Web sites you have visited. Click Bookmarks, and a drop- down menu of the sites you have bookmarked appears. Select from that list to returnto a site. There are several ways to add and change your bookmarks list: .Add Bookmark To add the address of the page that is currently being dis- played to your bookmark list, choose Bookmarks.Add Bookmark. The nexttime you click Bookmarks, you will see the bookmark you just added on theBookmarks menu. In addition to Web addresses, you can also bookmark anyfile or folder. .Edit Bookmarks Select Bookmarks.Edit Bookmarks to open a tree view ofyour bookmarks. From the Bookmark Editor window that appears, you canchange the URLs, the icon, or other features of the bookmark. There is also anice feature that lets you check the status of the bookmark (that is, theaddress available). .New Bookmark Folder You can add a new folder of bookmarks to yourKonqueror bookmarks list. To create a bookmarks folder, chooseBookmarks.New Folder. Then type a name for the new Bookmarks folder, andclick OK. The new bookmark folder appears on your bookmarks menu. Youcan add the current location to that folder by clicking on the folder name andselecting Add Bookmark. Configuring Konqueror OptionsYou can change many of the visual attributes of the Konqueror window, includingwhich menu bars and toolbars appear. You can have any of the following barsappear on the Konqueror window: Menubar, Toolbar, Extra Toolbar, LocationToolbar, Bookmark Toolbar. Select Settings, and then click the bar you want to haveappear (or not appear). The bar appears when the check mark is shown next to it. You can modify a variety of options for Konqueror by choosing Settings.ConfigureKonqueror. The Konqueror Settings window appears, offering the following options: .Behavior Change file manager behavior. .Appearance Change file manager fonts and colors. .Previews & Meta-Data An icon in a Konqueror folder can be made to resem- ble the contents of the file it represents. For example, if the file is a JPEG image, the icon representing the file could be a small version of that image. Using thePreviews features, you can limit the size of the file used (1MB is the default) because many massive files could take too long to refresh on the screen. Youcan also choose to have any thumbnail embedded in a file to be used as theicon or have the size of the icon reflect the shape of the image used.
