Silent Shutdown

---

I running silent boot.

But i want to complete silent the shutdown :)

But stil got messages from reboot or shutdown… Watchdog is currently disabled, but see just stil logout messages?

In /etc/default/grub I have variable

GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=3"

and see almost nothing at boot or shutdown, compared to the default setting.

Or course, changing that file requires also

sudo grub-mkconfig -o /boot/grub/grub.cfg

Which settings have you used?

i got :

GRUB_CMDLINE_LINUX="quiet loglevel=3 rd.systemd.show_status=auto rd.udev.log_priority=3 vga=current nmi_watchdog=0 nowatchdog"

and some stuf in sysctl and somestuf to silent the fsck …

using the ly tui , but stil got some bootmessages if i shutdown…

rd.systemd.show_status=auto becomes handy if your system is changes or whatever handy then it shows messages :)

i see on boot nothing after grub… then ly show up thats good only reboot or shutdown, i see things that stopped… dont know why exact but will see even got blacklist things :)

put watchdog back in :p but added splash seems some effect i guess…
but i shutdown a service probably was that also a case

Seems that kernel updates have quite much effect on what is shown at boot and shutdown.
And for me, currently kernel 4.20 often causes about 2 minutes of unexpected wait at shutdown, kernel 4.19 does not do it. But that could be reversed at the next kernel updates…

yeah dont know why probably is more systemd update ? recent i did go back to sddm myself before was more a ly tui from aur… would rater use lxdm but i dont know how it goes with systemd exactly since lxdm only in maintainance mode is, but basicly is death :)

will see how it goes further but i gues is more to systemd

Just as a reminder, you can always test any settings like another DM on a virtual machine. Then you don’t mess up your production system. :)

those idont need so much :)
