I updated my linux last night and now I can't start unity. To open up the OS, typically I use the sudo startunity command and it opens, but now when I use that command it goes back to the terminal. I'm on an Acer Chromebook. I'll see if I can upload any screenshots. I'm pretty new to all of this, so I really need help.

EDIT: I couldn't get a screenshot here, so here is the script it gives me when I try to open up linux:


chronos@localhost / $ sudo startunity
