I had forgotten the gear wheel.. the last time I used it was when unity
came out as the new default and I preferred Gnome Classic. Thanks for
reminding me.

The default on the desktop system was "ubuntu", so I changed to "Gnome
on Xorg". The presentation details are different (obviously) but don't
bother me. However, I get exactly the same errors logged and slow input
events:-

I will try again but this time only start a terminal session. I realise
there is a lot of processes running to support a single graphical user
session, but I'll keep Chrome and Thunderbird out of the variables.
