I've tried again with 20.04. The story is not great so far.

20.04 seemed to install fine over the top of 18.04. The usual
whimpering about missing files, etc. but basically it came up OK with
the settings I had already.

A weird thing showed up when I attempted a reboot - my password no
longer worked, When I looked at it using the show-password option it
turned out the special characters on the keyboard were all over the
place, and at least two (_ and |) were totally missing, I was using
one of them in my password. Fortunately  there's an on-screen
mouse-operated keyboard option and I was able to get in that way and
change my password. Once I was fully logged in the keyboard was OK.

Can anyone suggest what may be going on with the keyboard?

Anyway the next thing was to see if the issue with the NVIDIA graphics
card was fixed, which meant removing the "nomodeset" option from the
grub parameters. The short answer is that almost nothing has changed -
it's back freezing once I get to the login page. This time, however, I
can get Alt-Ctrl-F3 to work occasionally, so I've been able to edit
the /etc/default/grub file, but when I tried to run "update-grub2" it
just hangs. A few sites suggesting tracking down and killing a couple
of processes which might be blocking it. Unfortunately at that stage
I've still got the screwed-up keyboard and can't pipe ps's output
through grep.

Any suggestions on this? If I can get 20.04 back where it was a couple
of hours ago I can live with it (no "suspend" is the main problem.)
Failing that, it will be a complete new install, which is a pain.
