The GRUB project unfortunately does not consider bugs from downstream projects. Ubuntu adds a bunch of patches not in the official GRUB releases. Please file a bug with Ubuntu.

Having said that, if you would like to help fix it. Build GRUB from git and see if you have the same problem.

If you do, could you see if this is fixed by this patch, which has not been accepted yet?

Also, you will get more eyeballs looking at this if you communicate directly with the grub-devel mailinglist.

System: Ubuntu 24.04 LTS with 6.8.0-31-generic kernel
Grub2 package version: 2.12-1ubuntu7
Various hardware: ASUS Nuc12WSKi3, Intel NUC12WSHi5, Intel NUC13ANKi5, Intel NUC7

The systems boots normally showing the countdown; if I disconnect and connect the display during the countdown, the system freezes at the countdown, doesn't boot and I have to turn off and on to recover the system.

I verified the problem on different hardware: the BIOS is configured to use EFI boot with secureboot enabled.

- ASUS Nuc12Pro (model: Nuc12WSKi3): the system freezes at boot countdown, after reconnecting the display I see the grub interface on the display

- Intel NUC13ANKi5/Intel NUC12WSHi5: the system freezes at boot, after reconnecting the display it remains black

- Intel NUC7DNK2E: the system boots correctly, after reconnecting the display I see the grub interface on the display and the countdown continues until the system is booted

I tried to update the bios with the latest version and nothing changed; the same freeze happen with or without secureboot enabled.

Attached files:
- /etc/default/grug
- /boot/grub/grub.cfg

If there's any other test to do, I'm a skilled C/C++ developer and I can build grub2 with additional debug info.

Thanks
