Acer C720 running in low-graphics mode

[Ichigo1174]

I have an Acer C720 with Ubuntu 14.04.2 and it installed just fine. When I boot it up it gives me an error "The system is running in low-graphics mode" Like this I can not go into any of the settings or change anything. I can access the console
CTRL-ALT-F2 and then it prompts me for a login.

mojombo told me to use this command:
sudo bash main.sh -u USERNAME -n

Replace USERNAME with your desired username. Your password will be codestarter. If you install this way, then you'll be able to login with those credentials.

I tried it using sudo bash main.sh -u Ichigo1174 -n
and many other variations as I can think of.
it keeps telling me login incorrect.

any other ideas?
