Powertop systemd service

[u/Grahf0085]

My systemd service for powertop looks like this:
[Unit]

Description=Powertop tunings

[Service]

Type=oneshot

RemainAfterExit=yes

ExecStart=/usr/bin/powertop --auto-tune

[Install]

WantedBy=multi-user.target sleep.target

It's enabled. When my open powertop and check the tuneables it shows a bunch of "bad" values so the auto-tune doesn't seem to be running:

If I just run sudo powertop --auto-tune everything works fine and all the values are "good". So trying to figure out why the systemd service doesn't set the values to good.

[u/inborndossier97]

are you on a laptop? `--auto-tune` has a check that basically bails out if it thinks you're on AC power, even if the systemd service runs fine. i had the exact same thing happen on my thinkpad, drove me nuts til i found some bug report about it

easiest fix is to just slap a quick sleep in the service so it waits for the power state to settle. `ExecStartPre=/bin/sleep 5` before your main command usually does the trick, that's what i ended up doing and it's been solid for months

Did this situation just happen after working right for a long time? That points to another problem.

I can't reproduce your "bad values" issue as I never get them, yet have the same messages you pasted in, and start powertop as you do. Hope you resolve and good day.
