Bug ID: 510194
Summary: Sensors randomly swap with each other between boots
Classification: Plasma
Product: plasmashell
Version First 6.3.6
Reported In:
Platform: NixOS
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: System Monitor widgets
Assignee: [email protected]

Target Milestone: 1.0
SUMMARY
Between boots, sensors randomly swap with each other. As in you add and name
`/dev/sda` and `/dev/sdb`, reboot, sometimes the name you gave to `/dev/sda` is
swapped with `/dev/sdb`. This leads to the system monitor widgets misleading
you about which drive is being used. I know this is because Linux doesn't
guarantee the `sd*` names are consistent between boots, but the widgets should
probably be using UUIDs which *are* guaranteed to be consistent between boots.
STEPS TO REPRODUCE
1. Have a PC with more than 1 SSD/HDD (not NVMe)
2. Open System Monitor
3. Add a new page
4. Edit the page
5. Click on the widget
6. Set Display Style to Line Chart
7. Add a sensor for SSD/HDD and a sensor for a different SSD/HDD
8. Reboot and check if they've swapped
OBSERVED RESULT
Sometimes they swap.
EXPECTED RESULT
They don't.
