I was somehow able to get past this by removing then reinstalling all NVIDIA packages.
I ran this to remove the packages:
sudo apt-get remove "nvidia-*"
sudo apt-get autoremove
Then I rebooted, and then ran
software-properties-gtk
This brought up the Software & Updates window. In the Additional drivers tab, I selected 331.113 from nvidia-331-updates, and rebooted.
Unity would then not run (not sure if this would happen for others). I reenabled it by running
sudo apt-get install compizconfig-settings-manager
ccsm
And in the CompizConfig Settings Manager, I enabled the Ubuntu Unity Plugin.
I still have nvidia-331-updates version 331.113-0ubuntu0.1 installed.
