I edited the /etc/default/grub file and changed:
This does make Ubuntu boot up into text mode; however, it gets stuck while booting up and it does not show me the login text. Instead it says something like this:
Begin running /scripts/init-bottom USB hub found ...More irrelevant things... *Stopping LightDM Display Manager
I can press Ctrl + Alt + F2 and see the login and boot up like normal, but is there any reason for this? How can I change it so it does not get get stuck?
Edit: After 5 minutes, a new line came up:
