[Bug 1863434] Re: 20.04 grub menu not visible

[Fritz Hudnut]

BTW . . . I had similar issues with getting my various linux distros to
produce a TTY in nouveau, so I got advice to "go nvidia driver" . . . so I
did that, but then, because I'm in rolling or devel for most of them, stuff
started "breaking" with update/upgrades . . . because I don't think nvidia
is "keeping pace" with the bleeding edge distros, or perhaps even leading
edge . . . .  My card is maybe 7400???  posted on the nvidia linux forum,
guy got back to me, basically said, "Your card is very old news, so don't
hold your breath" . . . so I didn't.  Went back to nouveau in my ubuntu
20.04 installs, and some opensuse . . . but for tumbleweed I went with
"default" by not accepting nouveau in the install . . . not sure which
driver it is, but display is just as crispy . . . it's fine.

But, this "grub not showing the menu" issue seems to be working it's way
through all of the various distros . . . I did my chroot maneuver that
worked last time, didn't seem to get it this time . . . but, now in my
MacPro if I boot with no "alt/option" key held I get an OSX dmesg-like
window that loads and then "welcome to grub" shows up, but, if I hold
alt/option to an EFI disk boot . . . grub is all busted up . . . .
