[RHCE-124] single yuan, GNOME graphics desktop entry

Originally in version 5, the RedHat official team barely paid much attention to graphic desktops. However, in version 6, it may be due to the habit of migrating SAS from windows, therefore, in the RH124 course, the basic operations of some systems are demonstrated in the form of a graphical interface. In this regard, there are not many things to talk about, which is basically a little drag-and-drop problem. Main Content: log on to the desktop, change the password, log out, restart (reboot), shutdown (shutdown), lock screen (for root use)

Use of gedit Editor

The Gedit editor is similar to notepad in windows, but it is much more powerful than notepad, such as setting the background, setting the programming language, and supporting automatic indentation, it is good for programmers. However, I still do not recommend that you get used to it. Later we will learn the powerful text editor vim (enhanced version of vi)
