Login black screen?

[Jarvis]

So I had been using 2.0 for about three weeks or so and today I open my laptop and boot up. Everything was normal until I logged in... When I logged in I still had my cursor but nothing else loaded, it was just black. I have not made any big changes to my laptop since I started aside from fixing it so I could use my volume up and down buttons. I currently have it in command line and I am wanting to update all of its packages and have it install them but I don't know how and I am unsure if that is referred to in another thread.

I am running a stock acer c720 chromebook (minus the chrome part) I just need to find the update install script to see if updating will fix the issue.

Any help would be great.  ~Jarvis
