Thank you very much.
Before the update, I had a working NVIDIA driver installed and both
monitors were functioning normally. After the update, the second monitor
stopped working. So it would appear the update left the system without a
working nvidia kernel driver.
I ran " sudo ubuntu-drivers autoinstall " and it now appears to be
fixed. :) :) :)
