Same problem on a fresh install of Ubuntu 19.10 x86_64 on a Toshiba
Satellite U405. Another curiosity is that plymouth fails to display
anything on the splash screen, it is just black until the system fully
boots up.
Removing splash from /etc/default/grub disables plymouth.

See the same bug on my HP Spectre x360 15t.

Well, it's quite frustrating that the bug still persists even on 18.04. I'm
using Xubuntu 18.04 with updates installed and the plymouthd had 25% CPU usage
on ThinkPad T43p. I found a workaround on how to disable it. The process won't
bother you again.

Sorry, made a mistake in previous comment (package version given is for
16.04.5).
Actually, the package version on 18.04.2 is plymouth
0.9.3-1ubuntu7.18.04.1

I did not have this problem until recently changed default theme. Now
plymouthd utilizes ~15% cpu.
sudo killall plymouthd

I just noticed this behavior. "sudo plymouth --quit" is my current
mitigation, as well.

I have the exact same bug. plymouthd runs at a little under 5% all the
time after a reboot. I kill the plymouthd process so it doesn't waste
electricity. But it starts up again and does the same thing next boot.

This is what the daemon is doing wasting the CPU:
$ time sudo strace -p465 -c
strace: Process 465 attached

When plymouthd is burning up 5% of the CPU it also prevents Ctrl-Alt-F6
from giving you a console login. Instead you get a black screen that
just echoes what you type.
After "sudo plymouth --quit", the 5% waste is gone and Ctrl-Alt-F6 gives
you a console login prompt.
