Extra terminal running before shutdown
I'm running linux mint 13. Whenever I shutdown a terminal appears (not like the application but an actual fullscreen terminal) with the label tty1 and a prompt for a username to login. The computer always shuts down just fine but I am wondering why there is an extra terminal running in the background. I recently used ctrl-alt-f1 to bring up a terminal and shutdown, could that have caused this to happen? How do I stop the terminal from running in the background?
