Kubuntu Vivid slow to shut down

[Donatas G.]

Thank you Felix and Kaj for suggestions. I could not get to see what
happens during shutdown, no mater what I tried according to the link Felix
suggested.

However, I have sort-of solved the problem. For some reason (although I had
no proof it might be related) I continued investigating the the possible
plymouth involvement in the long shutdown process. Maybe because I would
not get the splash during shutdown - only a black screen with cursor
blinking at the top left corner.

first of all I noticed that in the plymouth conf scripts in /etc/init/
there are references to lightdm being waited for, while lightdm is no
longer used as a default. I tried to change those entries to sddm, but it
changed nothing.

Then I tried to see what services related to plymouth there are on my
system.

$ sudo service plymouth-<tab> revealed these ones:
plymouth-halt        plymouth-quit        plymouth-quit-wait
plymouth-read-write  plymouth-reboot      plymouth-start

so I stopped plymouth-reboot by running

sudo service plymouth-reboot stop

and tried rebooting. To my surprise, the system rebooted in three seconds.

So I googled on how to disable plymouth-reboot service and came up with
this:

sudo systemctl disable plymouth-reboot.service

and now the system reboots fine.

Hope the

sudo systemctl disable plymouth-halt.service
and
sudo systemctl disable plymouth-poweroff.service

will do the same for shutdown.
