This is probably one of the weirdest problems I have ever had in all my years of using linux. I recently installed Ubuntu into a chroot on my Chromebook, and installed a lot of software. Today, after rebooting and re-entering unity, I see weird black bars around menu items, and over top of almost all windows. I've tried everything I can think of. I've reset unity and compiz multiple times, reinstalled ubuntu-desktop and unity, but nothing has worked. I can't even take a screenshot of the problems because the screenshot window is also just a black box. I still have access to the command line. Please help.
EDIT: I was able to take a picture with my phone and upload it. Black boxes
