Bug Description

Boot animations start too late to be useful

Modern systems spend all their boot time (a couple of seconds) decompressing the kernel. During that time the user only sees the static BIOS logo (ACPI BGRT). Then when Plymouth can finally start animating, the startup process is already finished and there's virtually no time left to show any useful animations.

This could be fixed in:

  grub: By adding a splash under the BIOS logo to show some progress _before_ a Linux kernel is even started

and/or

  plymouth: By preferencing legacy framebuffer devices (like EFI) over DRM, if we find those are available a few seconds sooner. That would also fix bug 1868240 completely, and bug 1836858 mostly as the flicker moves to when the login screen starts.
