2.02+dfsg1-12ubuntu2: terminal not initialised in GRUB_TIMEOUT_STYLE=menu

[Andy Whitcroft]

Since the update to 2.02+dfsg1-12ubuntu2 my grub menu is no longer visible, specifically the bios vendor splash is maintained right through grub to plymouth. I am (perhaps) unsual in that I have the menu always enabled:

  GRUB_DEFAULT=0
  GRUB_TIMEOUT_STYLE=menu
  GRUB_TIMEOUT=10

A downgrade to 2.02+dfsg1-12ubuntu1 restores the terminal.

It looks very much like the changes in the patch below are insufficient for the menu activation to initialise the terminal:

  * debian/patches/efi-console-set-text-mode-as-needed.patch: in EFI console,
    only set text-mode when we're actually going to need it.

I'm unable to reproduce this on an X230 or T450s. I would have thought the firmware to be pretty similar, at least enough that I could see this issue when a similar config is applied.

This needs more investigation in the code for the console module. I've had a quick look, nothing obvious jumped out; and I've also confirmed that while this patch is still not upstreamed, it is applied on other distros (Fedora).

Could you give some details on the installation? Is it using bios or uefi mode?
Do you have only one OS installed? (likely, otherwise you would get the menu without having to change the configuration)

Could you add your boot log to the bug?

It's a bit weird that menu works in case of multiple OS installed but that it's behaving differently changing the config?
