Description Akseli Lahtinen 2022-02-23 11:27:59 UTC 
SUMMARY
I've made my own widget presets in the System Monitor app for GPU and CPU temperatures. 
Sending the widget directly from System Monitor works fine. 

However, loading preset through the System Monitor Sensor widget doesn't load it properly. For example instead of getting the GPU temperature line chart, i get an empty piechart.


STEPS TO REPRODUCE
1. Create a CPU temperature linechart preset with System Monitor  app
2. Add System Monitor Sensor widget to desktop
3. Load the CPU Temperature preset in the widget settings
4. Widget wont load correctly

This also fails if you try to directly load the preset through the Add Widget menu.

OBSERVED RESULT

Widget fails to load and shows an empty pie chart instead of the created linechart preset. 

EXPECTED RESULT

Widget would load the correct preset.

SOFTWARE/OS VERSIONS
Operating System: Kubuntu 21.10
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0

ADDITIONAL INFORMATION

I have checked the preset `faceproperties` file in the `~/.local/share/plasma/plasmoids/org.kde.plasma.systemmonitor.cputemperature/contents` folder and to me it looks correct, so System Monitor should be saving the preset correctly at least.

Here's the preset I used

```
[Config]
highPrioritySensorIds=["cpu/cpu0/temperature"]
lowPrioritySensorIds=[]
totalSensors=["cpu/cpu0/temperature"]

[FaceConfig]
historyAmount=60
lineChartFillOpacity=10
lineChartSmooth=true
lineChartStacked=false
rangeAutoX=false
rangeAutoY=true
rangeFromX=0
rangeFromY=0
rangeFromYMultiplier=1
rangeFromYUnit=-1
rangeToX=50
rangeToY=100
rangeToYMultiplier=1
rangeToYUnit=-1
showGridLines=true
showLegend=true
showYAxisLabels=true

[SensorColors]
cpu/cpu0/temperature=122,66,3

To add, I also use the kubuntu backports ppa.
Comment 2 Arjen Hiemstra 2022-04-28 14:15:58 UTC 
Yeah I can reproduce this. I wonder if it's more fallout from the desktop-to-json conversion...

Faces: Write preset faceproperties to the right location

When loading presets we expect the faceproperties file to be located in
"contents/config/" but when writing we are placing it in "contents/"
which means that custom presets are not loaded properly.

Comment 5 Arjen Hiemstra 2022-05-11 09:28:11 UTC 
Note that unfortunately the above commits don't fix presets that were exported previously - we actually did not write the correct thing. If you have presets that you want to preserve, you will need to find them in "~/.local/share/plasma/plasmoids/org.kde.plasma.systemmonitor.*". Those directories contain a "contents" directory that contains a single file "faceproperties". This needs to be moved to a "config" subdirectory in the contents directory and then the preset should start working.

Tested it, can confirm this works
