I would like to totally disable text messages on boot. I would like to see only the plymouth animation.

I have this on my /etc/default/grub:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=0 systemd.log_level=0 rd.systemd.show_status=false rd.udev.log_level=0 splash net.ifnames=0 biosdevname=0 vt.global_cursor_default=0"
GRUB_CMDLINE_LINUX=""
GRUB_RECORDFAIL_TIMEOUT=$GRUB_TIMEOUT

But sometimes at the end of plymouth theme appear boot messages show in photo.

How it's possible disable and not only hide text boot message?

The system version is Lubuntu 22.04LTS

Thanks Mauro

  • You could try fastboot kernel option. – lemmy Jul 17 '22 at 16:21
  • I don't think this is 100% achievable on all hardware.. as I've found changes that will do it on 24 of 25 boxes; but there are the odd box around that has firmware that causes the kernel to spit out a message that can appear on some video cards (where all other devices are silenced). That 1 of 25 will need a different/unique config change. 24 of 25 is guess, but I have >25 boxes I occasionally use in QA esp. with Lubuntu – guiverc Sep 04 '23 at 03:20

Try edit your /etc/default/grub file like this:

GRUB_CMDLINE_LINUX_DEFAULT=quiet   #Don't show Ubuntu bootup text
GRUB_CMDLINE_LINUX="console=tty12" #Don't show kernel text

After editing the file, you need to run update-grub.

sudo update-grub

(source)

This might work, in my case no message is shown, but I have Ubuntu 22.04 with full disk encryption.
