[Bug 1823259] [NEW] Update from grub-common AMD64 2.02-2ubuntu8.12 to 2.02-2ubuntu8.13 removed some Grub settings

[emptythevoid]

Public bug reported:

First, let me say that I don't have a lot of information, and will be
happy if this is a "just me" thing.  But here's what happened.  Today
around 8:30am on Ubuntu 18.04.2 HWE, I performed an apt update and apt
upgrade.  Among the things that got upgraded was for grub-common, among
a few others.  Upgrade proceeds without error and I continue to use my
laptop.  A few hours pass and a shut down my laptop.  When I turn it
back on, it boots, but the screen doesn't redraw properly.  Full-screen
windows don't properly show up, everything is real slow to render, mouse
is slow to move.  I did a few things like try to switch to lightdm and
reinstall xserver-xorg, but that didn't help.

What *did* help was check on /etc/default/grub.  My laptop needs to have
the Linux kernel parameter i915.modeset=1 in order for the display to
work normally.  For some reason, this was absent after the update from
this morning.  Considering grub-common updated, this is my suspect,
however I don't know why it happened.

I'd be welcome to include additional information, but I don't know what
to provide.  And as I said, maybe it's just me.
