Just corrupted my system trying to upgrade my amdgpu driver and had to move to
Focal (20.04) a few years sooner than planned. In doing so I realized
posthumously that the newest driver did not support versions of the linux
kernel greater than Linux 4.15.0-112. As it was an AMD issue I have marked my
report as "invalid".
(written from my new 20.04 system)

Title:
After grub updates the video display is wrong
Status in linux package in Ubuntu:
Invalid
Bug description:
After today's updates, including:
grub-common:amd64 2.02-2ubuntu8.18
grub-efi-amd64-bin:amd64 2.02-2ubuntu8.18
grub-pc-bin:amd64 2.02-2ubuntu8.18
grub2-common:amd64 2.02-2ubuntu8.18
grub-pc:amd64 2.02-2ubuntu8.18
grub-efi-amd64-signed:amd64 1.93.20+2.02-2ubuntu8.18
I was dual booting into Windows and back, so that I can say with
certainty that the bug started affecting me today when I came back
into Ubuntu.
I get the error "Failed to start Load Kernel Modules" and my video
monitor is restricted to "Unknown Display" 1024 x 768 but works
correctly otherwise.
On August 26 the kernel updated to 4.15.0-115 from 4.15.0-112 which
seemed to cause no problems.
I don't see any other likely suspects in today's upgrade, BUT it is
fixed by booting into the prior kernel version 4.15.0-112, leaving an
interplay between grub and the newer kernel as a likely culprit.
