As a follow-up, my system ran fine for a little bit with the fixes I mentioned in post #115, but then after a while the screen went black and I couldn't do anything but hold the power button in to power off.

This is not very fun - I am trying to set up Ubuntu for a Windows user, trying to convert her, but if the system randomly crashes like this, the conversion is bound to fail.
