Maybe my mistake, but in most docs about installing nvidia drivers thye say
remove -- purge old drivers first

A mix of 640x480 windows on a 1920x1200 screen (bottom of each window not
reachable) and if I tried to shrink a window the system froze up, as did any
terminal at random points

I did after another day wasted, conceed and go for a fresh install option,
(with intent to try thord party ppa) on the grounds that anything I may learn
sticking with it was out weighed but the lost time
I did not have any backups of the 20.04 system, as /Home had not changed really
since the upgrade 18.04.5 > 20.04, but I did have one from 18.04,
I did the fresh install (with update during install) and had a working (albeit
only 1024x768) system, added the ppa, ran the fix, all looked good, was going
to backup before doing anything else, got as far as starting backup app, but
changed mind and went for a reboot first
On reboot screen was now 1920x1200, did a few minor changes, icon size, set
night-light, added terminal to dock, and then thought a backup would be a good
way point (just in case) BUT Backup had gone, no sign of it anywhere, have I
found another strange bug? I cant even find it in Ubuntu Software to install
(assumes app is called Backup ??)

that had me confused, as 5.8.0-59 did have NI
lshw & lspci both show the card as "unclaimed" on 5.11.0-27

It is a "normally" stable work horse on most OS's and as I'm no gamer fine for
my use, it plays 720p & 1080p movies without a twitch (on VLC)
Many thanks, I've learned a lot
