13.10 - Black borders, black terminal
I was able to fix the black borders in Ubuntu 13.10 with the commands below. Although I did not have problems with terminal not showing text.
Reset compiz settings:
dconf reset -f /org/compiz/
Then restart Unity:
setsid unity

I had the same problem. I fixed it by installing Mir, following these instructions:

I had to use XTerm because Terminal was all black.
