Configuring Ubuntu

Unlike some versions of Linux, Ubuntu doesn’t rely on a centralized configuration software package. Instead, it uses smaller programs to configure hardware. For example, to configure the network, you’ll use the NetworkManager program, and printers are configured using a separate printer configuration program. Because using some of the configuration software involves reconfiguring your entire system, doing so requires administrator privileges. Therefore, you’ll be prompted for your login password each time you use some of the programs. In some cases, after you’ve made changes, you’ll need to click the Apply button to put the changes into effect. When you’ve finished configuration, simply close the program window by clicking the Close button.
