I have a Dell 11 chromebook on which I downloaded crouton, and through that, ubuntu 12.04. 12.04 was working perfectly well until I got a message from the update manager asking me to update to trusty 14.04, so I did.
I clicked yes and forward on whatever I needed to. When it was finished I shut down my chromebook and did something else. On my return I boot up crouton and type sudo startunity. It says stuff and eventually brings me to a black screen with an x cursor that has a white border.
A password prompt comes up and I type in what my password was for ubuntu 12.04. Nothing happens, so I hit the keys Ctrl+Alt+-> and try to log on there, but it also doesn't work. I am so confused, can anyone help me? :(
