I pressed ctl alt 1 typed my password in ect the it come up with a green line what to do next as I am new to all this
OK, EXACTLY WHAT
is on the screen after you press <ctrl><alt>F1? It should give you a black screen with some white text... on my system I get:
Linux Mint 17 Quiana <My system Name> tty1
<My System Name> login:
At this point you would put in your user name then it'll ask for your password.
Somehow I don't think you have a text only console at all.
If you substitute F2, F2, F4, F4, F5, F6 or F7 for F1 after <ctrl><alt> you would open different consoles:
tty2,3,4,5,6 and tty7 - as marked in my quote above.
if you used F8 you would get the Graphic User Interface (GUI) if it was available.
Am I right? Can you confirm what you get please?
