Hello all. I'm new to Kali Linux so I need a pretty detailed explanation on how to install (or just use) Kali Linux without the GUI. I have an older computer I would like to use this on. Like a VERY old computer. Right now it's running backtrack 5. But I don't use the startx command. Simple. But Kali's super-convenient GUI starts automatically. So again I'll ask:

How do I run Kali Linux without the GUI?

I would really appreciate a detailed answer.
