The situation is now that, after much experimenting and rebooting,  I'm not able to boot to my normal desktop (mate),  but can get to a terminal on the Ubuntu desktop.  I've switched off the new USB drive for the moment. And I'm having to type this from my tablet. So unless someone specifically knows the answer I'm going to have to reinstall 😣
