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.
Further to this it might be nice to have an image for each of the choices in
the grub menu which gets displayed when the menu item is selected.
