8. A Booted System
a. The board will have a mouse pointer appear on the screen as it enters the Linux boot step.
You may have to move the physical mouse to get the mouse pointer to appear. The system
can come up in the suspend mode with the monitor in a sleep mode.
b. After a minute or two a login screen will appear. You do not have to do anything at this
point.
c. After a minute or two the desktop will appear. It should be similar to the one shown in

system to look exactly like the one in the figure, but it will be very similar.
d. And at this point you are ready to go! Figure 16 shows the desktop after booting.
