Chapter 4. How Linux Works

Before you can effectively use a desktop environment, you need to know some Linux fundamentals. This chapter explains basic Linux concepts that underlie graphical and nongraphical system use. It describes Linux user accounts and how Linux organizes data as filesystems, directories, and files. This chapter also explains how to use the X Window System (often known simply as X). Because both GNOME and KDE are built on top of X, an understanding of X is central to using either desktop environment. Even though you're probably eager to get working with your new system, I suggest you at least skim this chapter. I also predict that you'll come back to it when you have some more experience and run into something confusing.
