Hello KDE community,

I'm having an issue with the Power Management settings of my KDE neon installation: the power button has no action at all when pressing it.

My Power Management settings:


What I know:

• The button is not broken. If I assign the shortcut sleep to the button, pressing it puts the system to sleep.
• PowerDevil is working. If I set the "when lid closed" action to "lock screen", my screen is indeed locked after closing the lid.
• The only setting not working is the power button behavior.
• It doesn't work no matter which option I select "sleep, hibernate, ...".

What I tried:

• Playing with the different options to see if it fixes anything -> Nope.
• Assigning a shortcut to the power button. It works but doesn't reproduce the behavior that I want.
• Executing `systemd-inhibit --list` to see if anything looks odd. It doesn't to me :
  

  Code: Select all

       Who: UPower (UID 0/root, PID 1074/upowerd)
    What: sleep
     Why: Pause device polling
    Mode: delay

     Who: ModemManager (UID 0/root, PID 884/ModemManager)
    What: sleep
     Why: ModemManager needs to reset devices
    Mode: delay

     Who: PowerDevil (UID 1000/antoine, PID 16901/org_kde_powerde)
    What: handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch
     Why: KDE handles power events
    Mode: block

     Who: NetworkManager (UID 0/root, PID 900/NetworkManager)
    What: sleep
     Why: NetworkManager needs to turn off networks
    Mode: delay

     Who: Screen Locker (UID 1000/antoine, PID 16741/ksmserver)
    What: sleep
     Why: Ensuring that the screen gets locked before going to sleep
    Mode: delay


My system info:
- KDE neon 5.18 user edition
- KDE Plasma 5.18.3
- KDE Framework 5.67.0
- Qt 5.14.1
- Kernel 5.3.0-40-generic

Note: I don't have a long experience with Linux, an even shorter one with KDE and none with asking for help on forums.
So, feel free to request any additional information.

Thanks for your help!

Are these your power management settings for AC Power or Battery? It works without problems on my system, so maybe something is different in yours.

Those were my AC settings but I tried both.

I actually fixed my issue by resetting to default my power management shortcuts.
I still don't know exactly what happened. All I can tell is that I assigned the power button to the "Hibernate" shortcut and that unassigning it did not solve my problem.

Thank you
