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.

This is a bug. The 'splash' option is configured, but text messages from the kernel are being shown.

Hello,

I have spin up two VMs with the exact same specs, one using the 20.04.4 Desktop ISO and other the 22.04 Desktop ISO.

Please check the attached file "Screencast from 24-04-2022 16:39:39.webm".

GRUB config for both VMs:

GRUB_DEFAULT=saved
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
GRUB_SAVEDEFAULT=true
GRUB_DISABLE_OS_PROBER=false

As you can see, the 22.04 VM is definitely more verbose, taking splash screen out of the way.

And please remember these are VMs. On my real hardware I get even more messages that are interfering even more (just some low severity Kernel warnings that already existed before in Focal but they weren't interfering with the splash screen) (check attached file 20220422_014058.jpg).

The boot time is the same so this is definitely a low prio/cosmetic thing. But still something has changed that shouldn't.

Not sure if this is of any use, but just fyi, the fsck messages seem to come from here [1]. The USB messages are just dmesg logs.
