I have a machine running Ubuntu 18.04.3 LTS server.
At some point it stopped the verbose onscreen kernel messages during a shutdown or reboot, including the status of the stopping of services.
For the most part the screen is just empty now, without any messages showing the status of shutdown.
The messages I am thinking of are the same you'd see by default in Debian and if you tapped Esc on the splash screen for a standard Ubuntu install.
The startup messages still show, it's only the shutdown messages.
A setting may have been changed at some point to change this behavior, but if so, I can't remember what.
The value of kernel.printk in /etc/sysctl.d/10-console-messages.conf is 4 4 1 7
The value for GRUB_CMDLINE_LINUX_DEFAULT is maybe-ubiquity. There are no quiet or splash values.
Thanks.
