Lenovo Yoga 260/KDE - No tablet mode (Screen rotation / On screen keyboard)


I am new in the openSUSE world and installed Tumbleweed KDE on my Lenovo Yoga 260 convertible. In general, everything works out of the box but I cannot find any settings regarding tablet mode.
That means: Nothing happens/changes if I fold my display. There is no auto rotation of the screen and no auto on screen keyboard appearing.

Did I miss something in the settings? The needed sensors are working, the rotation works in other distros.

Thank you!
