nvidia-legacy-304xx-alternative:i386 (304.131-1, 304-135-2)

One of possibly hundreds of packages upgraded on:

Start-Date: 2017-03-28 02:17:28
End-Date: 2017-03-28 05:12:29

Nothing else about this package in the log file.  No errors apparently.

# dpkg-reconfigure nvidia-legacy-304xx-alternative
Processing triggers for nvidia-legacy-304xx-alternative (304.135-2) ...

This seems to have fixed it.  Update-glx --config glx now returns 4
choices and /usr/lib/nvidia in auto mode is the current choice.

Thanks!
