missing sysvinit config for power-profiles-daemon

I am trying to access power profiles for AMD laptop (thinkpad 14s Gen4 AMD).

Devuan daedalus works well in general on this laptop but trying to set power profiles fails.

install:

apt install power-profiles-daemon

try to access power-profiles:

# powerprofilesctl get
Failed to communicate with power-profiles-daemon: g-dbus-error-quark: Error calling StartServiceByName for net.hadess.PowerProfiles: Launch helper exited with unknown return code 1 (25)

looks like the service is not running.

There is no sysvinit definition but there is a systemd unit file:

[Unit]
Description=Power Profiles daemon
Conflicts=tuned.service auto-cpufreq.service system76-power.service
Before=multi-user.target display-manager.target

[Service]
Type=dbus
BusName=net.hadess.PowerProfiles
ExecStart=/usr/libexec/power-profiles-daemon
Restart=on-failure
# This always corresponds to /var/lib/power-profiles-daemon
StateDirectory=power-profiles-daemon
#Uncomment this to enable debug
#Environment="G_MESSAGES_DEBUG=all"

# Lockdown
ProtectSystem=strict
ProtectControlGroups=true
ProtectHome=true
ProtectKernelModules=true
PrivateTmp=true
RestrictAddressFamilies=AF_UNIX AF_LOCAL AF_NETLINK
MemoryDenyWriteExecute=true
RestrictRealtime=true

[Install]
WantedBy=graphical.target

running the command directly does allow access to power profile:

/usr/libexec/power-profiles-daemon

I am looking to create a sysvinit file for this daemon.  I think I can do that with just the daemon command, but not sure if it should be connected to Dbus more explicitly?

Re: missing sysvinit config for power-profiles-daemon

There is another solution - power management using DE.
In Trinity, for example, there is a tdepowersave program in which everything is configured in 15 seconds.
It hangs in the tray and issues warnings when necessary.
KDE5 has something similar.

Another question is that in Daedalus, turning off the laptop when closing the lid (this is how I set it up) happens every other time, sometimes it “falls asleep” in the middle of the process and to continue you need to open the lid.
There was no such glitch in Chimaera.

Regards.

I have a copy... (not sure if I may post it here in code tags???)
happy to share.

Maybe it'll work for you. Just look out for start and stop levels being consistent with your system.

Re: missing sysvinit config for power-profiles-daemon

Thanks GlennW, a useful script!

There are a few things to consider as far as the best power management solution...

Here are some useful references:
- https://www.reddit.com/r/thinkpad/comme … ittle_fan/
- https://wiki.archlinux.org/title/Lenovo … -State_EPP
- https://www.phoronix.com/review/linux-65-thinkpad
- https://www.phoronix.com/news/Linux-6.6 … Management

Currently, I am using the 6.5.0.0. kernel from daedalus-backports.

aluma, if you are having sleep issues, you may want to try that kernel, no sleep issues for me.
However, the wifi driver doesn't wake from hibernate (known issue for that kernel driver)
- https://wiki.archlinux.org/title/Lenovo … ibernation

Note that I have tried the suggestion from the reddit post above and getting good power utilisation rate now (around 5.5 - 7W which should give close to 10hr battery life).

echo 'power' | tee /sys/devices/system/cpu/cpu*/cpufreq/energy_performance_preference

I will write up an install guide for Devuan for the laptop soon, but looks really good and should improve even further with new kernel releases.
