CHAPTER 10 PERSONALIZING UBUNTU: GETTING EVERYTHING JUST RIGHT 4. Click the Find button, and then close the Search dialog box. 5. Change the line the Find routine has highlighted to remove the hash mark from the beginning, so it reads like this: spindown_time = 24 You can alter the value to anything you want. Each time unit is five seconds, so 24 equates to 120 seconds (24 5 seconds), or 2 minutes. To set a time of 20 minutes, enter 240 (240 5 seconds). If you specify a number above 240, the time units are increased to 30 minutes. In other words, a value of 241 will equate to 30 minutes, a value of 242 will equate to 60 minutes, and so on. 6. When you ve finished, save the file. 7. Reboot for the settings to take effect. POWER SAVING IS IT WORTH IT? An average computer draws anywhere between 100 to 500 watts of power. An average light bulb draws around 150 watts of power, so you can see that, relatively speaking, computers are low power consumers compared to many household devices. However, it s still worth considering employing power-saving techniques. You might not save yourself a lot of money, but if you switch on power saving, and your neighbor does too, and her neighbor does, then the cumulative effect will add up, and we can all contribute less towards global warming. Try to avoid leaving your computer turned on overnight, or when you re away from it for long periods. As well as saving power, switching off your computer will avoid wear and tear on its components. Although the CPU can work 24/7 without trouble, it s cooled by a fan that s a simple mechanical device. There are other fans in your computer too, such as the graphics card fan and case fan. Each of these will eventually wear out. If your graphics card fan stops working, the card itself will overheat and might burn out. The same is true of the CPU fan. However, by shutting down your computer overnight, you can effectively double the life of the fans and radically reduce the risk of catastrophic failure. Isn t that worth considering? Summary In this chapter, you ve learned how to completely personalize Ubuntu to your own tastes. We ve looked at changing the theme so that the desktop has a new appearance, and we ve examined how to make the input devices behave exactly as you would like. In addition, you ve learned how to add and remove applets from the desktop in order to add functionality or simply make Ubuntu work the way you would like. Finally, we looked at the power-saving functions under Ubuntu and how you can avoid your computer wasting energy. In the next chapter, we will look at what programs are available under Ubuntu to replace those Windows favorites you might miss.
