I just updated to Ubuntu 12.10 and once the computer booted I get the issue described here:
I want to try the first solution, reinstalling ubuntu-desktop, but when I enter CTRL + ALT + F1, I get prompted to enter my login details (attached).
I thought my username would be 'Zach', but I tried that and numerous other possibilites and none of them worked. I am entering in the correct password.
Is there another "Zach login:" that I should be trying?
