it defaults to "None" already. But Kconfig defaults are only applied on the first run. Once you saved a config and re-opened it, Kconfig can't tell anymore what is left to the default and what was set on purpose, so it treats everything as if it was set on purpose. > >> This is very odd.

I can pull the logs for you. A common issue with GRUB, loaded from SeaBIOS, is that its configuration might expect a specific resolution (and the ability to ask the BIOS for it). With libgfxinit, the BIOS can't change the resolution. Maybe just try with the textmode framebuffer and without any `grub.cfg`. If that works, you can try to switch to the linear framebuffer.
