The first thing you will need to know is how to log on and log off using your allocated user (or login) name.
At the login screen (which will appear similar to the one shown in figure 1.6 on page ) type
If you make a mistake typing your username and password, you will get the message `Login incorrect', or something similar. Should this happen, just try again. When you enter your username and password correctly, you will see several windows on your screen. These are explained in more detail in The X Window System (chapter 4, page ). For now, just move the mouse pointer over one of the larger windows (known as xterms) to enter UNIX commands in that xterm.
Logging off is simple, you simply move the cursor onto the background window, hold down the right-most mouse button, and select the Logout option from the menu bar. The menu bar should look like figure 2.1.
