Issue with chroot on Chromebook

Ok, I seem to have this random crashing issue with Xenial on my Chromebook. It runs fine for weeks, then decides it will crash every time I switch from ChromeOS to Linux. Usually, I can open a Linux session but when I flip-flop back and forth, the whole machine freezes.

Annoying.

For my own sanity, I've started logging the troubleshooting I have done.

First, I ran an update. Then I decided maybe I wanted to do this in a tab to prevent these problems. So I added xiwi: 

sudo sh ~/Downloads/crouton -t xiwi -u -n xenial

Something seemed to die when I did that process. My next step was to check the updated install.

sudo enter-chroot

This line is annoying, the first time I replaced "-chroot" with "xenial". That's wrong, actual use the term provided: "-chroot". That went wrong, too. However, this seemed to work: 

sudo enter-chroot -n xenial

Next, I installed the crouton integration extension.  

Next step:

sudo startxfce4

Now, we wait to see what happens.
