Dear Brian,

I have been able to have grub2 display a background image on my
fedora linux system. It works as long as I don't use secure boot.
After I have my selection the image remains on the screen until the
boot is complete and I see a login screen. Fedora adds a spinner
during this process. What I would like to see is the framebuffer
cleared to black (zeroed??) similar to the code in
gfxterm_background.c
if (grub_gfxterm_background.bitmap)
{
grub_video_bitmap_destroy (grub_gfxterm_background.bitmap);
grub_gfxterm_background.bitmap = 0;
grub_gfxterm_background.blend_text_bg = 0;
/* Mark whole screen as dirty. */
grub_gfxterm_schedule_repaint ();
}
Just don't know where to put the code and what the real code would be.
I do not fully understand, what you want to accomplish.
But, you can disable ACPI BGRT in the Linux kernel with by adding
`bgrt_disable` to the Linux command line.
Otherwise, you should probably look into Plymouth, on how to configure
the background in GNU/Linux [1].

Kind regards,
