Greetings to all,

Is there someone could tell me if it is possible to get working fbsplash with a Macbook Pro (9.1) and UEFI stub kernel ?
I tried a lot of different way without any success.

Then I installed splashutils with themes according to the Gentoo Wiki and enabled the fbcondecor flag.
I also added in fbcondecor to the rc-init boot.

In my kernel configuration I put for the kernel parameters this
Code:
root=PARTUUID=D43FF789-F974-4472-82A8-3AE027B3DB8D


To manage fbsplash initramfs I created a new entrie with efibootmgr like this
Code:
efibootmgr --create --part 2 --label "Gentoo-Splash" --loader '\efi\gentoo\grubx64.efi' -u "splash=verbose,theme:powered_by_gentoo initrd=\efi\gentoo\initramfs-bootsplash.img"


The kernel boot with success but I do not get any splash during the entire boot and even after.

I'm finally just asking myself if it is possible.

Something also strange the entrie created by efibootmgr looks not good:
Code:
Boot0000* Gentoo-Splash HD(2,GPT,be8fb9d4-93dc-444a-ae9e-053490ae6de0,0x1800,0x40000)/File(\efi\gentoo\grubx64.efi)s.p.l.a.s.h.=.v.e.r.b.o.s.e.,.t.h.e.m.e.:.p.o.w.e.r.e.d._.b.y._.g.e.n.t.o.o. .i.n.i.t.r.d.=.\.e.f.i.\.g.e.n.t.o.o.\.i.n.i.t.r.a.m.f.s.-.b.o.o.t.s.p.l.a.s.h...i.m.g.


Thank you for your help

I think you need to use CONFIG_INITRAMFS_SOURCE instead of passing the initrd via efibootmgr.

EFI uses UCS-2 encoding for strings so efibootmgr output looks normal.

Thank you for your answer.

I found something! If I tried to set manually on tty the fbsplash theme I get this message :
Code:
Failed to open the fbcon_decor control device
