Jay Flory, your information was the key! I removed the -116 kernel and reinstalled it, and the graphics are fine now. It looks like this was indeed due to a timing problem between when my system got the gcc update and the kernel update.
It appears that I'll have to reinstall virtualbox as well. Thanks so much for sharing your insight. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750937 Title: 4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and 16.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1750937/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
