Description Zoey Ahmed 2024-06-22 19:40:39 UTC
SUMMARY
On a new Install of Fedora KDE 40, in the power management profile I am unable to change my power profiles or get the battery life left in my laptop [Image 1] , and when I hover it, it states I do not have a battery in my laptop despite the fact I do [Image 2] , and it is detached using upower [Image 3] .
Power-profiles is running without any errors [Image 4]. All 3 power profiles are detected in powerprofilectrl and I am able to change them and have the changes detected. [Image 5].
For reference, I am using the power management widget by itself instead of in the system tray as by default in KDE Plasma. 
When I installed GNOME, it detected my battery and allowed me to change my power profiles properly.

SPECS
My laptop is a Lenovo Ideapad 5i Pro Gen 5, with these specs:
Operating System: Fedora Linux 40
KDE Plasma Version: 6.1.0

Qt Version: 6.7.1
Kernel Version: 6.9.5-200.fc40.x86_64 (64-bit)

System Version: IdeaPad 5 Pro 14ITL6 

STEPS TO REPRODUCE
1. Install Fedora 40 KDE Plasma on a laptop with a battery
2. Remove the system tray and add the power profile
3. Observe the above described behaviour.
Comment 1 Zoey Ahmed 2024-06-22 19:47:09 UTC
FWIW, I just checked and in the power management panel in the system tray it does report all the information correctly.

Comment 2 Jakob Petsovits 2024-06-23 10:25:23 UTC
Let me confirm: You added a Power and Battery widget to your desktop, and displays different (incorrect) values there compared with the version in your system tray?

But also in the original imgur album, the second image shows "No Batteries Available" when hovering over the system tray icon... so it's not just the stand-alone widget that's showing wrong values?

That is correct. The system tray version is fine, but the standalone power widget is broken.

Nope thats the standalone widget, the system tray power widget does show my battery, sorry for the confusion
Comment 4 Totore 2024-06-24 07:20:38 UTC
I'm also having that issue.
I can look at battery level and infos in "Infos about System" in KDE Control Center but not in the Plasma Applet.

Comment 5 César Montoya 2024-06-27 15:46:33 UTC
Can confirm same behavior, from a fresh install of KDE Plasma on Fedora 40, I added the "Power and Battery" widget to the panel, and it displays no batteries, as well as the power-profiles not supported message, relevant terminal outputs (https://pastebin.com/t75TdtHc).

Additional information: Removing the widget and adding it again fixes the issue, but it will appear again on next boot.

I am also experiencing the same issue. This happens every time I boot up linux. I am using an empty panel and I have added the battery as a widget in that. I have to manually remove and re-add the widget for it work properly.

Comment 8 César Montoya 2024-07-28 12:57:23 UTC
I found something interesting about this bug, it would be useful if the others can confirm the behavior:

This issue only appears if you boot WITH the charger connected, when booting the laptop without the charger connected (a.k.a. using battery) the issue is not reproducible.
Comment 9 Nate Graham 2024-07-29 20:27:44 UTC
Fascinating. I can reproduce that with my Lenovo ThinkPad X1 Yoga (gen 4) laptop.

Zoey, can you reproduce it as well?

I tried two times without the charger connected, I can't confirm what you saying, still the issue persist.

And that is indeed my fault, forgot to add some details :P

While trying to fix the issue I added "acpi_osi=Linux" to the kernel parameters, that's what mitigated the issue and made everything ok when booting without the charger connected, for reference.

Give it a try and tell me if there's any difference.

Tried but nothing changed, the only workaround it's the one you mentioned before. Adding again the widget in the panel resolve the issue, but that has to be done every restart of the system.

Sorry for the previous noise, I don't know how it solved consistently that time, but it is in fact not a solution, only workaround is what we already agreed upon
Comment 14 Jakob Petsovits 2024-08-12 20:48:56 UTC
I'm going to assume that the issue is in the way that the applet [1] initializes its values. When it is started, it sends a query to D-Bus once per D-Bus service ("org.kde.Solid.PowerManagement", "org.freedesktop.PowerManagement", "net.hadess.PowerProfiles") to see if the interface is present. If the D-Bus service does not exist at initialization time, the applet will stay empty forever.

If any of the queried interfaces isn't online yet, e.g. because plasmashell and its wallpaper desktop area with widget were faster at starting up, then the widget will remain empty. I think it's likely that this is what we're seeing here.

The applet should change its code to observe when an interface gets registered or unregistered, probably with a QDBusServiceWatcher. Once the interface is found or disappears, update the values for use by the applet's QML.

Is this something you could start a merge request for?

I can, but I have a few higher-priority tasks on my list that I'd like to land before 6.2 beta gets released. I'll add the "junior-jobs" label in the meantime, in case someone else is looking for a relatively easy fix to contribute :)

applets/batterymonitor: React to D-Bus service (un)register events

Previously, the "Power and Battery" applet only checked for the
presence of PowerDevil's D-Bus services once when it starts up.
This appears to (mostly?) work for applets embedded in a panel,
but does not work for applets on the desktop itself.
Likely there's a timing issue and applets on the desktop start
sooner than PowerDevil will advertise its services.

A better way to work is for the applet to monitor the bus for when
the relevant services appear or disappear. When observing a service
registered or unregistered event, the applet gets set up accordingly.

This fixes the race condition for two out of three applet parts
(power profiles, inhibitions) but does not fix battery status;
the data for that is coming from `BatteryControlModel`
in plasma-workspace. A similar fix will have to be implemented there.
