[ubuntu] Booting to a login screen

view story

http://ubuntuforums.org – Hi I've just installed 12.04, which is nice but a little too automated for my liking. I would like to be able to boot to a tty login screen, as I used to be able to do in 8.04. After logging in, I'd like to be able to login and then manually open my windows manager, as I did with 8.04. Could somebody explain how I might do this in 12.04? Following another post, I tried changing the default run level in /etc/init/rc-sysinit.conf to either 1 or 3, rather than the default 2, but neither option gave me an old-fashioned login screen. Thanks! (Hardware)
