You are a star Daniel.

I followed the instructions at #80 under Bug 97822.  That is:
Disabled Legacy Mode
Disabled Secure Boot
both options were on the same Advanced BIOS panel.

I then re-booted without success.

So I went with the final bit of the instructions and re-installed Ubuntu.
Success!
I updated the software and re-booted.  Still at full screen.

Now all I have to do is get Ubuntu set up again!

edids.bin was still empty.

Regards,
Glenn Stewart
