Kubuntu Vivid slow to shut down

[Donatas G.]

So now I can do a fast reboot, halt the system, but - only using command
line. If I choose to shutdown the system through the Kicker menu, it still
takes almost two minutes.

I have disabled these plymouth-* services:

plymouth-halt.service
plymouth-poweroff.service
plymouth-quit.service
plymouth-reboot.service
plymouth-quit-wait.service

 but these ones remain enabled, as I am afraid to touch those:

plymouth.service
plymouth-read-write.service
plymouth-start.service
plymouth-kexec.service
plymouth-log.service

Anyway, to disable something is just a workaround. Hope to find real
solution some time.
