Terry, I am unable to make it through the install process with secureboot enabled.
I did install bionic with non secureboot, then enabled secureboot via EnrollDefaultKeys, and upon the subsequent reboot, the text console was fine, quite readable. The version of shim as reported by 'apt-cache show shim' is: Architecture: amd64 Version: 13-0ubuntu2 This is what shows after installing without secureboot enabled; so I'm not sure if the install process has updated shim from what is on the .iso. The problem really only appears to manifest upon installation. I don't have the know-how to swap out the shim on a bionic .iso.

The GRUB screen works just fine, but as soon as the kernel boots, the "text" mode becomes garbled. One can tell that it is text, but it is wholly unreadable.
