Well, nothing showed up in the log.

Things change as soon as the GRUB2 menu is past it's process off.  I
searched for video, mirror, clone, resolution and everything I could.  I
didn't find anything about the change in video.

I have not had time yet to look at how to change the boot process to
single step to find which process is changing the screen setting.

I don't have my notes handy.

Part of me is thinking of waiting for F19 and doing a clean install
again to see what happens.  I may do that on a partition for testing.

On the other hand, it would be worth knowing to make sure it doesn't
happen to others.
