How do I turn-off verbose logging during boot?

Support
1

Hello guys,
When I installed Manjaro, the booting process would be non-verbose and I could see the login manager directly after POST. However, after updating Kernel, I now get a full verbose output before login screen is launched. The same thing happens while logging out. I would to like to turn off this behavior. Please help.
Changing grub to quiet has done nothing.
Thanks for any suggestions!

normally, the boot process is (relatively) silent
unless you changed the grub configuration
to not be silent

what could certainly help here - if you can’t figure it out - is:
post the contents of

/etc/default/grub

If you made no changes to it - the boot process should be … silent

… lets see what you have got

Here it is:

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=hidden
GRUB_DISTRIBUTOR="Manjaro"
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3"
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on"
GRUB_CMDLINE_LINUX=""

# If you want to enable the save default function, uncomment the following
# line, and set GRUB_DEFAULT to saved.
GRUB_SAVEDEFAULT=true

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"

# Uncomment to enable booting from LUKS encrypted devices

Merge the content of the second line into the first line. Then delete the empty second line.

After changing the file enter the command

sudo update-grub

and reboot.

I did as advised.
Should I also delete the third line which has nothing but quotes?

No.
Leave it as it is - and perhaps read up on what this is used for.

Do as @Wollie suggested - I suspect that of the two identically named lines
with different content
GRUB_CMDLINE_LINUX_DEFAULT= ...
only the last one (the second one) is taken into account - thus the settings to make the boot quiet are not applied - only the
intel_iommu=on
setting in the latter line

Thanks worked like a charm.
