Powersave mode extrem

Linus67

I was monitoring the journal with “sudo journalctl -f” while I turned the Wi-Fi on and off. I noticed that when turning on the Wi-Fi, a connection attempt by the daemon fails.

sudo journalctl -f

dekko does it too.
IIRC every app that is installing a systemd service I have looked at don't remove it when uninstalled.

Thank you! That's a bit above my paygrade.

As @uxes wrote

Run the following commands in the Terminal.

systemctl --user stop ubconnect-daemon.service
systemctl --user disable ubconnect-daemon.service
rm -f ~/.config/systemd/user/ubconnect-daemon.service
systemctl --user daemon-reload
systemctl --user status ubconnect-daemon.service

result:

Unit ubconnect-daemon.service could not be found.

@Linus67 As I said, the first two were what I did, after figuring out they might be helpful.
Can I be a little proud of myself for figuring that out? I'm not a terminal user at all.

rm -f ~/.config/systemd/user/ubconnect-daemon.service

Thanks to this hint, I knew where to find it and removed it using the file manager.
All clear now!

The advantage of using the GUI in this case was that it showed me what else lived there. There was another daemon that was no longer needed. So that was helpful.

@gpatel-fr yes that is just missing thing of click packages since they don’t have some kind of postinstall and postuninstall hooks to insert and remove those systemd services

@uxes

It's a feature, taken from the click documentation:

4.3.2 Specification
• Only system packages (i.e. .debs) may declare hooks. Click packages must be declarativeinclude code executed outside AppArmor confinement, which precludes declaring hooks.

@Moem If you're still experiencing increased battery drain when using Wi-Fi,
go to Wi-Fi -> Network Settings -> Saved Networks and tap “Forget” to remove all saved networks. Then reconnect to your home Wi-Fi network.

I also had a few stale connections here—sometimes even two Wi-Fi icons in the status bar.

Thanks... the truth of the matter is that I've just migrated to a different device. So there are no saved networks. But also I don't know the state of my current battery.

@Moem
After clearing the saved Wi-Fi connections, power consumption is minimal.
