eoan boot hides grub menu

[Alan Griffiths]

I dual boot several Ubuntu versions and have edited /etc/default/grub to show them on boot (and default to the last used).

When eoan installs grub I no longer see the grub menu listing them during boot.

Holding the shift key doesn't help.

Although not displayed the menu seems to be active as I can select another install by using the cursor keys and enter.

Reinstalling and updating grub from 18.04 restores normality - once I've found 18.04 by guessing where it is on the (hidden) boot menu.

Uh, ok, apparently apport-collect needs to be told the binary package name to collect against instead of the source package? apport-collect -p grub-common 1836934, please

What are the contents of /etc/default/grub now?

Setting a GRUB_TIMEOUT to -1 should be sufficient to always show the menu, I'd expect, or is that what is not working?

I'm setting it to 10 (attached) but, yes, that's what is not working: I can use the menu (up/down/enter) but can't see it - just the "Lenovo" logo.

I can confirm seeing this on Thinkpad W550s. Grub menu is there, but not visible on screen, which is stuck on previous bios output. Installing 18.04 grub fixes the problem.

Happening to me on HP EliteBook 8460p UEFI install and Ubuntu MATE 20.04!
Tried all sorts of GRUB_TIMEOUT and GRUB_TIMEOUT_STYLE settings to no avail.

GRUB menu *IS* actually there but it won't show up: it just freezes on a black screen until the timeout expires or a key is pressed.

[tom (gcvl)]

Manually downgrading to GRUB 2.02 from Bionic "solves" the issue.
Grub-efi 2.04 seems to be broken, then.

[tom (gcvl)]

grub-efi version 2.04-5 installed from Debian archives does not have this issue.

Is this a duplicate of #1863434 ?
