The grub2 EFI binaries in F41 break flicker-free boot by always printing "dynamic_load_symbols %p\n" during boot. Reproducible: Always Steps to Reproduce: 1. Boot a Fedora 41 install with the grub-hidden-menu feature active (default for non multi-boot Workstation installs) Actual Results: 1. Notice vendor logo go away and a text briefly flash by, even though the grub-menu is hidden 2. Also EFIFB switches from the native monitor resolution of 1920x1080 to 1024x768 because of the EFI text console getting initialized. Expected Results: Flicker free boot. I am attaching a patch which fixes this. It would be nice if this fix can be included in the F41+ grub2 build before the F41 final freeze on October 15th.
Created attachment 2050232 [details] [PATCH] Stop grub.efi from always printing "dynamic_load_symbols %p\n" during boot Note I have not submitted this patch to grub upstream since the problem is introduced by a downstream patch.
Hi Hans, thanks for the patch. I am assuming I also need to apply this patch in rawhide ?
(In reply to Nicolas Frayer from comment #2) > Hi Hans, thanks for the patch. > I am assuming I also need to apply this patch in rawhide ? Yes the patch is actually based on top the rhboot/grub2/fedora-42 branch. Offtopic, comparing the distgit patches vs rhboot/grub2/fedora-42 it seems that 0276-efi-loader-Check-if-NX-is-required-in-grub_efi_linux.patch is missing from rhboot/grub2/fedora-42 ?
ok I'll apply your patch on f42/f41/f40 after it's all sync'd Thanks for pointing the missing patch, that must have slipped out of my list.
