Shutdown button reboot the machine

Hello,

openSuse Tumbleweed on laptop Lenovo x270 running KDE.

I can’ tell when it started but for some weeks now when I click on shutdown button (KDE menu), the machine do no shutdown actually. Instead it reboot. I have no idea where to look in order to solve this issue. The behavior is not random. It occurs every time.

Do you have any idea ?

Thank you.

I’m not a KDE user myself Maybe this could help: KDE System Settings/Power Management

System info?
Here is what I see when pressing the power button and shutdown from the laucher. I’m setup to show logout screen. see screenshot

I just updated and ran into the same problem, only “session” was available in the KDE menu.

The following post on the arch forum worked as a temporary workarround, but it definitely needs a proper fix.
