Thanks Samuel. Are you saying that grub command is not allowed if F37
because F37 is now booting via grub with full secure boot enabled,
whereas with the way F36 booted that grub command was honoured and the
menus and theme were displayed in that resolution with full secure boot
enabled?
That was just a guess and I think it was wrong now. I checked the
source and that error message is related to file loading. I would have
to see your config file to make a guess about what file it was trying to
load.
