[Bug 1869655] Re: Boot animations start too late to be useful

[Daniel van Vugt]

** Summary changed:

- The Plymouth splash starts too late to be useful on modern fast systems
+ Boot animations start too late to be useful

** Description changed:

- The Plymouth splash starts too late to be useful on modern fast systems.
+ Boot animations start too late to be useful
  
- Such systems spend all their boot time (a couple of seconds)
+ 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.
