Thanks for posting that! I wound up selecting the Nouveau driver in the Additional Drivers tab, then switching back to the recommended NVIDIA driver, and then I reset my system. After I did all of that, I was able to launch my system normally again! I guess that the graphics driver wasn't set up properly during the install process.
