[Bug 1970069] Re: Annoying boot messages interfering with splash screen

[Mario Limonciello]

Yeah; so try forcing plymouth to the Ubuntu initrd like this:

echo "FRAMEBUFFER=y" | sudo tee /etc/initramfs-tools/conf.d/splash

Then if you rebuild the initrd you'll end up with plymouth in it.

This unfortunately DOUBLES the initramfs size; but it's because it puts all the drm modules in there.  
Here is where simpledrm really shines.  I belive /usr/share/initrams-tools/hooks/plymouth can be modified to stop including any drm modules and /usr/share/initramfs-tools/framebuffer can be totally dropped.

I believe this will guarantee plymouth wins the race.

Title:
  Annoying boot messages interfering with splash screen

Bug description:
  Since upgrading from 20.04.6 Desktop to 22.04, the boot screen is not
  as clean as it used to be.

  Basically, the flow used to be in 20.04:

  GRUB > Splash screen > Login prompt

  Currently in 22.04:

  GRUB > Splash screen > Messages (in the attached file) > Splash screen
  again for a sec > Login prompt

  All of those messages already existed in 20.04, the difference is that
  they were not appearing during boot.

  I was able to get rid of the "usb" related messages by just adding
  "loglevel=0" in GRUB. Currently is "quiet loglevel=0 splash".

  Regarding the fsck related message, I can get rid of them by adding
  "fsck.mode=skip".

  However, I do not want to just disable fsck or set the loglevel to 0.
  This is not a sustainable solution.

  Something definitely changed here. These messages are not of enough
  relevance to be shown at boot by default, and they should remain
  hidden like they were in Focal.

  Obviously a minor issue, but important to the whole look and feel of
  the OS for desktop.
