When you exit the nano-X server, it just exists, and anything you had on the
screen will stay in the framebuffer memory, becuase there are no other
processes that will be writing to the screen. Most of the time thats not a
problem, because you will normally have the graphics engine active the whole
time, but if you really want to clear the screen, I suggest clearing the
memory right before the driver closes the framebuffer (in drivers/scr_fb.c).
