So I tried JH's solution and it didn't work. Just to make sure I'm not skipping a step here's what I did:
1) after initial GPU hang, I logged in via ssh, edited /etc/apt/sources.list
2) added the gpg key
3) sudo apt-get update
4 sudo apt-get upgrade -u
5) restart
6) a few minutes after login, much less time than before, GPU hung again.. This time however I get a different error:

So it looks like it's not the back cache this time.. I think it's because those drivers are nvidia and mine is not?
