Well, I am not sure, but here are my first thoughts:
* Unity needs working OpenGL. Something may have knocked that out.
Stuff to try:
* If you can get a terminal, then you can update, right? So do that:
sudo -s
apt update
apt dist-upgrade -y
apt clean
apt autoremove
apt purge
shutdown -r now
* If that does not help at all, try starting with the kernel parameter
``nomodeset'' in case there are kernel graphics driver problems.
Google for info, it's a little involved and there are better
explanations than I can improvise in an email.
