Bug 483454

SUMMARY

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 #474016, except that according to powerprofilesctl switching profiles is successful, so it's most probably not a bug in power-profiles-daemon?

STEPS TO REPRODUCE

1. Click battery icon in taskbar
2. move slider to middle or right position

OBSERVED RESULT

The slider moves back to the left, `powerprofilesctl get` shows new state.

EXPECTED RESULT

The slider stays where I moved it, `powerprofilesctl get` shows new state.
