I think this is a combination of two things: first, we currently need to
unlock the drive once for GRUB, and then once when Linux boots, hence
the two password prompts. This is a known limitation, but the usual
workaround of adding a keyfile to the initrd wouldn't work in our case
for security reasons: the keyfile would end up in the store and be
world-readable, a disaster.
Regarding the second prompt being invisible, I think it might be related
to the framebuffer initialization for Libreboot since there have been
lots of reports about this. I don't know anything myself, but maybe
someone else could chime in?
Best,
