Fedora 29 x86_64 on a Gigabyte Brix.  dnf update berfore Xmas, worked fine.  Booted it today and it won't boot to the GUI.  Shows Gigabyte on the screen.  However, I can ssh into it.  (Thank goodness for ssh !)

The first two kernel packages are highlighted.  What is the significance of that ? 

The last package, 4.19.13-300 isn't highlighted.  It also doesn't show in the grub menu when the computer boots.  Why ?

How do I get it to boot again ?

Thanks
