When I turn on the computer ( or restart ) the screen turns on and off three times before booting grub. How to stop this behaviour?

Question

OS: Arch Linux x86_64
Host: 81Y3 IdeaPad L3 15IML05
Kernel: 6.8.1-arch1-1

~ λ  lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS

I have updated the UEFI to the latest version "EJCN31WW"

Information about the EFI partition:

File System: fat32
Flags: boot, esp

Grub configuration file:

GRUB_DEFAULT=0
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3"
GRUB_CMDLINE_LINUX=""
GRUB_PRELOAD_MODULES="part_gpt part_msdos"
GRUB_TIMEOUT_STYLE=menu
GRUB_TERMINAL_INPUT=console
GRUB_GFXMODE=1920x1080
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_DISABLE_RECOVERY=true

I have tried missing with the UEFI settings, but with no success.
I have noticed that if i entered the boot menu and selected grub the first time it turns on, it will boot grub right away.

So, what I think that it could be caused by (I'm probably wrong XD):

1. The EFI partition is too large (2Gb).
2. The EFI partition doesn't have the right format.
3. It tries to boot grub, but it fails.

What is the solution?

This is the boot partition tree:

Answer 1

Booting looks fine to me from a technical standpoint.

I think this is happening:

The resolution of the display gets changed for a split second to another resolution. As this is sooo early in the boot process it has no other way as to turn the display on and off.

My guess is that the Boot images you see like Lenovo Logo etc have a different resolution than your grub menu. Most pictures have 800x600.

As you do not get the changes when you halt "fancy" booting with pictures and directly boot the grub menu with the correct size.

I think its like this:

• Initial Power on Resolution -->> Maybe 480x600 don't know really ->> Initial Blank
• Lenovo Logo shows ->> Resolution needs to change for this ->> Resoultion gets changed to show Pic. Second blank
• Grub begins booting and request to change to 1920x1080 ->> Third Blank to show correct Grub resolution.

So my first advice would be lower the grub resolution to 800x600 and test if some of the blanks vanish. Also you could try to boot in debug mode so no picutes and logos are shown.

To answer your questions:

So, what I think that it could be caused by (I'm probably wrong XD):

The EFI partition is too large (2Gb).

• Thats fine. 512GB would be enough tho if you want to save some space

  The EFI partition doesn't have the right format.

• It does otherwise booting would not succeed. You would see and EFI shell if this would be the case.

  It tries to boot grub, but it fails.

• Then you would see a shell and would not be able to boot.

Answer 2

I didn't find an answer, so at last, I gone to the bios settings.

choose Legacy boot,

and Try UEFI first,

and that worked fine.

but still it won't work when I choose UEFI instead of legacy boot. I think it's something wrong with the firmware Lenovo shipped.

Thanks
