Re: Change Full Disk Encryption Password Prompt Font and/or Background Image (stage 1)?

[Cullen Ross]

Hi Hans,

Thanks for the response! Sorry if there is some confusion, I'm not trying
to set the keyboard layout. Thanks for the suggestions though!

Regarding fonts, I'm not sure which modules need to be loaded. I'm looking
at `moddep.lst` like you mentioned and there are a handful of various video
modules. My video card is intel if that helps. From what I understand, do I
place modules <some_video_module>, gfxterm, font in `GRUB_PRELOAD_MODULES`?
The gfxterm module requires the font and video modules, so do I place those
in front of gfxterm in the `GRUB_PRELOAD_MODULES` setting? Finally, where
do I put the `loadfont` command and where can the font file be if the disk
is encrypted? Perhaps in /boot/grub?

Lastly, if gfxterm is loaded early, does this mean I can issue a command to
set the image background?

Thank you so much!

Best,
Cullen
