Ubuntu – How to turn off the filesystem check message which occures while booting


What I want to achieve:

I want to customize my complete boot of my Ubuntu 16.04 LTS installation to show the same wallpaper which is actually on my desktop.

What I achieved till now:

  • added the wallpaper to the grub menu by adding the following lines to /etc/deault/grub and doing an update-grub afterwards.

    export GRUB_MENU_PICTURE="/boot/grub/wallpaper.png"
    export GRUB_COLOR_NORMAL="white/black"
    export GRUB_COLOR_HIGHLIGHT="black/white"
  • added the wallpaper to the splash-screen and login screen


When I boot up the picture is showing while in grub, but then I rarely see the splash screen, instead I get an almost blank screen showing the file-system check like following:

/dev/sda1: clean, 201776/60878736 files, 4991277/243040256 blocks

This prevents me from having the boot experience I want to achieve since after that the splash-screen just shortly popping up after that message.


How can I remove this message from showing up so I get a seamless booting with my beloved wallpaper, without switching the file-system check completely off (if possible)?

Silencing boot messages

You should be able to achieve this with the kernel parameter loglevel= or quiet

loglevel=       All Kernel Messages with a loglevel smaller than the
                console loglevel will be printed to the console. It can
                also be changed with klogd or other programs. The
                loglevels are defined as follows:

                0 (KERN_EMERG)          system is unusable
                1 (KERN_ALERT)          action must be taken immediately
                2 (KERN_CRIT)           critical conditions
                3 (KERN_ERR)            error conditions
                4 (KERN_WARNING)        warning conditions
                5 (KERN_NOTICE)         normal but significant condition
                6 (KERN_INFO)           informational
                7 (KERN_DEBUG)          debug-level messages

quiet       [KNL] Disable most log messages

I am not sure at exactly what level this would be hidden (or how quiet you would like your boot to be).


reboot your computer, and at the grub menu hit e to edit the boot parameters.

scroll down to the end of the linux... line using the arrow keys

add desired loglevel parameter or quiet to the end of that line. example:

linux      /vmlinuz-4.4.0-21.generic.efi.signed root=/dev/mapper/encrypted ro loglevel=4


linux      /vmlinuz-4.4.0-21.generic.efi.signed root=/dev/mapper/encrypted ro quiet

when done editing, proceed to boot by pressing F10


To do this, edit /etc/default/grub


uncomment it if needed, and add the desired log level or quiet -- for example GRUB_CMDLINE_LINUX_DEFAULT="loglevel=4" or GRUB_CMDLINE_LINUX_DEFAULT="quiet"

and run sudo update-grub

fsck messages

remove fsck from initramfs

fsck is run by default by the initramfs. by removing it and having systemd run fsck we will be able to redirect the output.

see man initramfs and wiki.ubuntu.com/Initramfs for more info on removing fsck from the ramfs.

systemd fsck

From the arch wiki:

Now copy the files systemd-fsck-root.service and systemd-fsck@.service located at /usr/lib/systemd/system/ to /etc/systemd/system/ and edit them, configuring StandardOutput and StandardError like this:



In Ubuntu, these files are both located in /lib/systemd/system

If the file system is not checked by the initramfs during boot, systemd-fsck-root.service will automatically be run.

see http://manpages.ubuntu.com/manpages/wily/man8/systemd-fsck@.service.8.html
