Missing Dash/Panel/Launcher

[Grizzly]

Hi

Clean install of Ubuntu 16.04.4, worked fine, then update & dist-upgrade (to 
16.04.5)

Now all I have is wallpaper (background) Dash/Panel/Launcher missing, only  
thing that shows (sometimes) is the update to 18.04.1 dialogue, then only for a 
fraction of a second, it goes away before I can click anything, it will come 
back lower on screen a bit later, and go again as quickly

I have tried all the normal solutions I can find, with no success

Booting

Advanced - Recovery - Resume

gets me in and running but would prefer been able to boot normally

Any pointers or tests to perform help find/cure this

It's a Compaq M2000 Laptop if that is relivant
