Are you running linux currently? You have a number of virtual terminals, commonly Ctrl+Alt+F1 through Ctrl+Alt+F7, with 1-6 running text consoles and 7 with your X11 session on it. If you boot into the GUI and spend all your time there, then although 1 will probably contain remnants of the boot process, 2-6 will be unused, a blank screen with some text in the corner.
