I see now that I had completely mis-diagnosed the problem. In fact the
problem is that the system is reverting to Unity-2D and if I select
'Ubuntu' at login then it is still using 2D, so the issue is not with
the settings at all (I assume that icon size is not adjustable on 2D).
The system was using 3D before the update.
I see:
$ /usr/lib/nux/unity_support_test -p
X Error of failed request: BadRequest (invalid request code or no such
operation)
Major opcode of failed request: 153 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 22
Current serial number in output stream: 22
which I guess is the problem.
