SUMMARY *** I have a Zenbook UM425QA (with a Ryzen 7 5800H), and selecting a power profile does absolutely nothing. The option has recently appeared in the system tray, but it's hard stuck on Balanced. The slider snaps back to Balanced if I try to drag it to Performance or Power Saver. However, the setting still applies according to `powerprofilesctl`, but you can't set it back to Balanced, because the slider says that the active profile is Balanced (even though it's not). Going into the Power Management settings, trying to set power profiles based on charging status works, but isn't represented by the slider. It's still stuck on Balanced. *** STEPS TO REPRODUCE 1. Go to Battery and Brightness on the system tray 2. Try to drag the slider to Power Saver (or Performance) 3. Check with `powerprofilesctl` if it works 4. Try setting the power profile to Balanced 5. Check with `powerprofilesctl` if it applies 4. Set power profiles for AC and battery power 5. Check with `powerprofilesctl` if the correct profile applies on AC and battery power respectively. OBSERVED RESULT The slider instantly snaps back to Balanced every time I try to move it in either direction, but the profile chosen does show as active if checked with `powerprofilesctl`. Setting it back to Balanced via the slider doesn't work. You'll be stuck either with Power Saver or Performance. In addition, unplugging or plugging in the laptop does set it to the profile chosen in Power Management, but it isn't represented correctly in system tray. This is a way to go back to Balanced mode, but it's finicky. EXPECTED RESULT The slider should stay on the active setting that is reported by `powerprofilesctl`.

Hmm, if `powerprofilesctl` works, than it sounds like it's not https://gitlab.freedesktop.org/hadess/power-profiles-daemon/-/issues/106.

While this bug report was done on an up-to-date system when I made it, I've since updated my laptop and it seems to be fixed. The actual scrolling is a little glitchy, but it at least works now. Should this be marked as resolved?
Sure. If you can't reproduce it, there's no chance any of us can debug it. And if it did really just randomly start working again, then it might indeed be https://gitlab.freedesktop.org/hadess/power-profiles-daemon/-/issues/106.
Created attachment 164877 [details] X11 plasmashell I have the exactly same issue: * powerprofilesctl successfully switches between profiles * KDE power manager is stuck on a single value (usually "balanced") * KDE power manager successfully switches the profile when the bar is dragged, but instantly returns to the default position * When you `kquitapp5 plasmashell && kstart5 plasmashell`, it starts to switch the profiles, but with bouncing (check the video) Seems like there's race condition somewhere. This is the recording on X11 Plasma session, works fine on plasmashell restart.

Can confirm. I used to have it on Intel i7 8550u laptop with Plasma 5 and hoped it would be eliminated in Plasma 6, but it's still present, and even on another machine with Ryzen 7840H. However it didn't manifest itself right after the fresh install of Manjaro which I am using on both machines, but a couple of weeks later I started to see it again.
*** Bug 483454 has been marked as a duplicate of this bug. ***
I've periodically had the same problem (jumps back in the applet but works via powerprofilesctl) recently in Plasma 5 too; I'll have to observe if it shows up in Plasma 6 as well.
For sake of completeness, I'll post the gist of my other report (that has been closed as a duplicated of this one): I'm using the current development version of KUbuntu 24.04 with plasma 5.27.10-1ubuntu1 and power-profiles-daemon 0.20-3ubuntu1 on a Framework Laptop 13 with AMD Ryzen 5 7640U. The energy profile slider always jumps back to the "Save Energy" state, no matter which mode is actually set according to `powerprofilesctl`. Both setting another profile with the slider and with `powerprofilesctl set balanced` (or "power-saver" or "performance") works, according to `powerprofilesctl list` and `powerprofilesctl get` and `cat /sys/firmware/acpi/platform_profile`. The slider however always jumps back to the left, and the text above it always resets to "Power Save" This is very similar to the existing reports in this bug, except that according to powerprofilesctl switching profiles is successful, so it's most probably not a bug in power-profiles-daemon?

Can someone tell me where I can find the source code for this? Searching for "battery" on https://invent.kde.org/ didn't give me any results.
According to my observations the slider jumps back to the previous state (not only left), which was set during the start of Plasma. No matter what that state was. Profiles switching works, it's only slider acts weird until plasmashell is restarted.

Invent's search functionality is not particularly useful in many cases. lxr.kde.org does a better job in general, in particular for cross-repository searches. You'll mainly want to look in two places: The PowerDevil action that implements power profile switching: https://invent.kde.org/plasma/powerdevil/-/blob/v6.0.2/daemon/actions/bundled/powerprofile.cpp Also look at: - the associated .h file - the corresponding .xml files for the D-Bus interfaces that it's using to communicate with power-profiles-daemon - org.kde.Solid.PowerManagement.Actions.PowerProfile.xml which uses the PowerProfile class to expose its own D-Bus service The Power and Battery applet: https://invent.kde.org/plasma/plasma-workspace/-/blob/v6.0.2/applets/batterymonitor/package/contents/ui/main.qml Also look at: - PopupDialog.qml and PowerProfileItem.qml in the same directory, which are child items of main.qml - The associated dataengine that exposes PowerDevil's D-Bus service to the applet: https://invent.kde.org/plasma/plasma-workspace/-/blob/v6.0.2/dataengines/powermanagement/powermanagementengine.cpp
Thank you, I might take a look at the source if I find some more time :)
I haven't looked at the code, but quickly tried the following (I'll add comments starting with "#" between the lines to document what I did): $ dbus-monitor "interface='org.kde.Solid.PowerManagement.Actions.PowerProfile'" signal time=1710353718.842724 sender=org.freedesktop.DBus -> destination=:1.164 serial=2 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameAcquired string ":1.164" signal time=1710353718.842774 sender=org.freedesktop.DBus -> destination=:1.164 serial=4 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameLost string ":1.164" # set profile to balanced with the slider (which immediately jumped back) method call time=1710353728.906855 sender=:1.41 -> destination=org.kde.Solid.PowerManagement serial=3938 path=/org/kde/Solid/PowerManagement/Actions/PowerProfile; interface=org.kde.Solid.PowerManagement.Actions.PowerProfile; member=setProfile string "balanced" signal time=1710353728.972333 sender=:1.46 -> destination=(null destination) serial=2018 path=/org/kde/Solid/PowerManagement/Actions/PowerProfile; interface=org.kde.Solid.PowerManagement.Actions.PowerProfile; member=currentProfileChanged string "balanced" # run `$ powerprofilesctl set power-saver` signal time=1710353735.988951 sender=:1.46 -> destination=(null destination) serial=2020 path=/org/kde/Solid/PowerManagement/Actions/PowerProfile; interface=org.kde.Solid.PowerManagement.Actions.PowerProfile; member=currentProfileChanged string "power-saver" # moving slider to performance (it immediately jumped back) method call time=1710353743.614882 sender=:1.41 -> destination=org.kde.Solid.PowerManagement serial=3939 path=/org/kde/Solid/PowerManagement/Actions/PowerProfile; interface=org.kde.Solid.PowerManagement.Actions.PowerProfile; member=setProfile string "performance" signal time=1710353743.654630 sender=:1.46 -> destination=(null destination) serial=2021 path=/org/kde/Solid/PowerManagement/Actions/PowerProfile; interface=org.kde.Solid.PowerManagement.Actions.PowerProfile; member=currentProfileChanged string "performance" This makes me wonder if this is the same bug as "my" other bug: https://bugs.kde.org/show_bug.cgi?id=471010 In both cases PowerDevil sends the correct DBus messages, but the UI sticks (or in this case reverts) to some nonsense-value, maybe one it set on boot or something. TBH I have zero experience with Qt development, so it would be nice if someone else could debug what's exactly going wrong in the battery monitor - or if you can't reproduce it, instruct me what to do :)
I'm experiencing the same with plasma 6.0.4 on arch. Killing and restarting the plasmashell fixes the slider and a possibly related bug where video playback and games would not inhibit sleep/screensaving.

Apparently there was an issue on our side, as it went away completely for me with a recent change to the widget for Plasma 6.1.

We generally aren't backporting anything to 5.27 anymore, sorry. There are exceptions for narrowly-targeted fixes and well-understood code. In this case that's not possible since the widget has been received a huger number of large changes between 5.27 and 6.1.
