[pic] Manage desktop

You have already learnt about the desktop. Let us try to revise what we studied. When the computer starts, the screen you see is referred to as desktop. On the desktop, you see icons that represent the different applications. You can start the activity by bringing the pointer of the mouse on top of the icon, then clicking on the mouse button once to select the icon and pressing the Enter key. The background is also called wallpaper

In this lesson, you will learn how to change the look of your desktop.

Imagine that after vacations when the school re-opened, you friend changed her hair style. Does she look different?

(kaumudi, insert a picture of a girl with 3 or 4 different hair style, one may be her tied in 2 plates, one very short hair and so on)

Similarly, what if your family decide to paste wallpapers on the walls of your room. Will it look different?

(kaumudi pics needed, of a room with a variety of wallpapers)

You can change the way the desktop of your computer looks. Just as new hairstyle of your friend makes her look different, the change of the wallpaper will give a new look to your computer desktop.

The following pictures illustrate two desktop wallpapers:

Let us learn how we can change the look of out desktop. Keep the mouse cursor anywhere on the desktop (not on icons/taskbar) and press the right mouse button. A dialogue window is displayed giving all the available desktop backgrounds and ask us to select a background.

The following figure illustrates the dialogue window that pops up.

All the available desktop background options are listed. You can also add wallpapers and remove existing wallpapers from the available desktop background list. For example, you may have the snap of your family stored in the computer. Yow can put it up as the wallpaper of your computer desktop.

We can also change the background colour using this option and the colouring can be given vertical or horizontal gradient effects. You can also change the Style of the wallpaper. The Style functionality helps us to decide upon how the selected wallpaper is displayed on the desktop screen. The four options under style are: Centered, Fill screen, Tiled, Scaled.

Centered: The selected wallpaper is displayed in the center of the desktop

Fill screen: In this option according to the size of the wallpaper it can be stretched to fill the whole desktop background.

Tiled: The wallpaper selected will be displayed in a tiled format.

Scaled: The wallpaper selected is scaled so that just covers the desktop area.

After you have selected the wallpaper and the style of how it is displayed, click on Finish. The following figure illustrates this. In the dialogue window shown, we click on the Edubuntu young wallpaper. The desktop changes as shown below. We then click 'finish' to exit.

For the Teacher

▪ First, revise the ideas of left-click and right-click taught in a previous class. Earlier, the emphasis was only on left-click. If required let the children play some games for exercising the right click. Suitable games can be found in the Childsplay and gcompris suites that are part of the Edubuntu system. To change the wallpaper:

▪ Keep a computer ready with a Desktop having simple and not so interesting/no wallpaper. Ask the children to identify the Desktop. Now tell them “ Let's make the desktop more colourful”.

▪ Let them distinguish between left click and right click. Once they are able to do that ask anyone of the kids to do a right mouse click anywhere on the desktop (not on the icons). A window opens up. (Make sure that you are ready with some nice wallpaper (for example figures with some cartoon characters like Tom and Jerry, Mickey Mouse or Superman, which will grab the attention of the children) in the available wallpaper list. Now you select the desired wallpaper and click the “Close” button.

▪ Now ask the children whether the new wallpaper is appealing, and if they would be interested in doing the exercise again. Then show them how you can select another wallpaper. Repeat the exercise twice or thrice.

▪ Adding or removing wallpapers can wait as it is too much of work for the little ones!! You can do the following exercises in the lab:

• Give a computer with a desktop having no wallpaper. Now ask them to select wallpaper and display it on the desktop (Don't insist on a particular wallpaper).

• Ask the children to change the existing screensaver (the computer can be set such once the computer is idle, within seconds the screensaver is active).

• Let them also change the desktop background colour.
