[Bug 1965689] [NEW] Black screen instead grub menu at boot

[Jeremie Tamburini]

Public bug reported:

Fresh install of Ubuntu 22.04 on multi-boot system.

Steps:
1. Switch on computer.
2. You see for about 10 seconds a black screen instead GRUB MENU.
3. After 10 seconds Ubuntu boots normally.

Extra tests:
- During the 10 seconds of black screen, I can press ENTER and Ubuntu will boot.
- I thought that maybe grub menu was just not visible but still there, so I've tried to use "arrow keys" (up and down) to select a different system and then press Enter... but nothing happened, the screen remained black.

** Affects: grub2 (Ubuntu)
     Importance: Undecided
         Status: New
