Summary: Grub2 freeze on boot when display is reconnected during boot countdown Group: GNU GRUB Submitter: saversa Submitted: Thu 19 Sep 2024 07:21:38 AM UTC Category: Booting Severity: Major Priority: 5 - Normal Item Group: Software Error Status: None Privacy: Public Assigned to: None Originator Name: saversa Originator Email: Open/Closed: Open Discussion Lock: Any Release: other Release: Reproducibility: Every Time Planned Release: None _______________________________________________________ Follow-up Comments: ------------------------------------------------------- Date: Thu 19 Sep 2024 07:21:38 AM UTC By: saversa <saversa> 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.
