Guys Chat GTP managed to solve it. It was about autostart order. He created script to restart powerdevil after start.

patryk@devuan:~$ cat ~/.config/autostart/powerdevil-restart.desktop
[Desktop Entry]
Type=Application
Name=PowerDevil restart
Exec=sh -c "sleep 5; /usr/lib/x86_64-linux-gnu/libexec/org_kde_powerdevil"
X-KDE-autostart-after=panel
patryk@devuan:~$

Thank you steve_v

Process is not alive, because it runs on demand/trigger. But it works. It changes profile when (un)plugging power source.

That's dbus activation failing to start whatever is providing UPower.PowerProfiles (likely because the shipped definitions expect systemd and the "Exec" entry is /bin/false, see /usr/share/dbus-1/system-services/org.freedesktop.UPower.PowerProfiles.service), which implies that it isn't already running, or if it is, it didn't register on the system bus.

Note sysvinit has no service supervision, so it'll say tlp-pd is "started" even if it later exited or crashed. Check that the process is actually alive.
The manual suggests tlp-pd takes a '--debug' flag, that's probably worth a look too.

That might be because tlp isn't advertising profiles that match what ppd would offer, or it might be a polkit thing... but those are just guesses. The message has changed at any rate, so kde/powerdevil sees a ppd implementation now, it just doesn't like it.

The only time I've messed with this nonsense is replacing ppd with tuned-ppd on gentoo/openrc... None of which is particularly relevant here.
You could perhaps have a look what tlp-ppd is providing on dbus (e.g. with qdbusviewer) and compare it to ppd.

Ed. What says (as root)

dbus-send --system --print-reply --dest=org.freedesktop.UPower.PowerProfiles /org/freedesktop/UPower/PowerProfiles org.freedesktop.DBus.Properties.GetAll string:"org.freedesktop.UPower.PowerProfiles"

(aside, the above BS syntax also illustrates why and how very much I hate dbus)

Thanks for your input.
What do you think about installing from source?
Script seems to be supporting sysvinit

TLP_SYSV
	/etc/init.d
Install directory for sysvinit script

https://linrunner.de/tlp/developers/makefile.html

Edit: I installed from source. Archive cointains tlp-pd and now it running but KDE is not talking to it. Any ideas?

patryk@devuan:~$ sudo service --status-all | grep tlp
 [ ? ]  alsa-utils
 [ ? ]  hwclock.sh
 [ ? ]  kmod
 [ ? ]  mount-configfs
 [ ? ]  networking
 [ ? ]  speech-dispatcher
 [ + ]  tlp
 [ + ]  tlp-pd

It appears Devuan does not ship a sysvinit script with tlp-pd (as usual, it's just the Debian package and no attempt was made to ensure it works properly without systemd), so somebody will need to write one.
I don't have any Devuan installs on laptops or any interest in tlp, so that someone isn't me. It should be trivial though, find an init script template and have it start /usr/sbin/tlp-pd after dbus and tlp.
...or just ask your artificial-stupid of choice to convert /usr/lib/systemd/system/tlp-pd.service, this is a pretty good example of something they should be able to do without screwing up.

Ed. Upstream just added an init script.
Grab https://github.com/linrunner/TLP/blob/main/tlp-pd.init, stick it in /etc/init.d as tlp-pd, make it executable, and enable it with update-rc.d.
Then either reboot or start the service manually then logout/login to kde.

Should work, YMMV, etc. Again, I have no desktop Devuan installs. vOv.

I installed it from backports, but don’t know how to make it work with KDE

Re: Kde profiles with TLP

dummy@example.com (steve_v) — Sat, 11 Jul 2026 12:04:52 +0000

Try tlp-pd from backports, apparently it provides the same dbus namespace as ppd, which is what kde is after to enable that applet.

dummy@example.com (patgaw) — Sat, 11 Jul 2026 11:34:39 +0000

Is that possible to make it work at Devuan with TLP? I heard TLP is better then power profiles daemon.
