[SOLVED] systemd service file for powertop

[doktor5000]

Running Mageia 5 on a MacBook Pro with KDE.

I created a file powertop.service and placed it in /etc/systemd/system. It looks like this:

Code: Select all

[Unit]
Description=Powertop tunings

[Service]
Type=oneshot
ExecStart=/usr/sbin/powertop --auto-tune

[Install]
WantedBy=multi-user.target

I enabled the service with:
systemctl enable powertop

I rebooted but the powertop service did not work properly.

Code: Select all

# systemctl status powertop

Not sure what the failing part is, the missing TERM variabe set or that it cannot load the config file /var/cache/powertop/saved_para...

Disappointing. I followed the approach outlined by the archlinux folks...

This powertop.service file works!

Code: Select all

[Unit]
Description=Powertop tunings

[Service]
Type=idle
Environment="TERM=dumb"
ExecStart=/usr/sbin/powertop --auto-tune

[Install]
WantedBy=multi-user.target

You might as well open a feature request in our bugzilla and propose that such a systemd service file should be added to our package in cauldron.

And FWIW, same as in the battery status thread, please try to use more meaningful thread titles, just using the program name as thread title is not that helpful for people searching for solutions.
