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

Sure one can check for "splash nomodeset" to avoid the confusion in most
cases, but that wouldn't fix it for "splash $DRIVER.modeset=0" or less
common architectures which might have no primary framebuffer. I guess we
can tell people who are debugging to remove "splash", and if such a less
common architecture did exist then report a new kernel bug that it has
no primary framebuffer.

Still, I'll keep searching for solutions that don't rely on the primary
framebuffer trick.

P.S. The patch in comment #55, and anything that follows it, has an
unexpected benefit that there is never an onscreen console created if
you never VT switched. And so bug 1870041 is also solved (well enough).

  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.
