SUMMARY
My tablet with mouse buttons, steam deck, does not expose accelerometer via iio-sensor-proxy. I believe plasma mobile will need to see an valid sensor in order to show any screen rotation toggle.

https://www.phoronix.com/news/Steam-Deck-IMU-For-HID-Driver


STEPS TO REPRODUCE
1. sudo systemctl start iio-sensor-proxy.service
2. monitor-sensor


OBSERVED RESULT
doof@localhost:~> monitor-sensor
    Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared

** (monitor-sensor:7534): WARNING **: 18:11:08.079: Failed to claim accelerometer: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name is not activatable

No screen rotation toggle.


EXPECTED RESULT
I can see the screen rotation toggle in the navigation bar

Comment 4 Devin Lin 2025-06-22 00:23:09 UTC

The intended function of https://invent.kde.org/plasma/plasma-mobile/-/merge_requests/624 was to allow users to change the screen orientation if the orientation sensor output differs from the orientation of the screen, and auto-rotate is disabled.

It will not show if the orientation sensor doesn't exist, because it can't determine what the system orientation is. What is the expected usecase?
