Power button not working

Support KDE Plasma
1

Hi!

My power button (on the desktop, not the physical button) does not work in Plasma desktop anymore. When I push it nothing happens. Switch user and sign out still works but look strange, with no theme, just black background.

I’m pretty sure that this happened after the second last update. I was waiting for the last update to possibly fix it but it’s still the same.

As of now I am getting around the issue by typing “systemctl reboot” in console, but would like to get the buttons back, even if it’s only a minor annoyance.

I would appreciate any solutions or ideas. Thanks in advance!

You have a “power button” on the desktop? If so you added it. Is it a widget, like the Lock/Logout widget? Most people put those in the system tray or a panel rather than the desktop itself. If it is a widget, right click and check the configuration settings for the widget and set as you desire. If that doesn’t help, then delete the widget from the desktop or panel and then re-add the widget. If it is a widget other than Lock/Logout - check with the widget developer and see if it is still supported. If my assumption about the “power button” being a widget is wrong, please give us a little more information to work with.

Hi, thank you for your reply!

I’m sorry if my description was unclear. What I mean is the overall power/reboot/shutdown function on the desktop. I do have extra widgets added for this purpose and they do not work either but neither does the power button in the start menu, the standard one that comes with the desktop. All my other widgets work fine, as well as all other links in the start menu.

Edit: I’ll add pic here to make it more understandable. My system is in Swedish but it is the last two buttons that don’t work at all (restart and shut down) as well as log out. Switch user and lock both work but look strange with all black background, not themed as they should be.

Please provide some information.

Hi again.

The problem in short is that power-related buttons on the desktop are unresponsive.

The issue started after the second last update. I have tried systemctl reboot and it works so the problem seems to be at the desktop level.

I’m currently using the latest kernel 5.15.7-1 and have also tried LTS 5.10.84-1. No difference there concerning the problem.

You have BIOS update available: ROG STRIX B450-E GAMING | ROG Strix | Gaming Motherboards｜ROG - Republic of Gamers｜ROG Global

Hi, thank you for your input :slight_smile:

Checked settings, mine looks the same.

Regarding the bios update, this is complicated with these ASUS boards as they use the same bios for different generations. The version I have is the latest one for Zen+ boards, the later ones are for Zen2 and Zen3. I made the mistake once of upgrading to a Zen2 bios. It worked but messed up a lot of things. I had to go through a painful process of rolling back the bios, which the regular update does not allow. So, after reading about it and seeing people recommend not to update, I chose to stay with this one.

Do you think it could be connected to the issues I’m having?

When you logout and get to SDDM, does the power off or reboot buttons work from there? Lastly, are you using a global theme other than Breeze or Breath? If so, try going to a vanilla Breeze theme and see if you have the same problems. I’m not smart enough to know if your bios might be the issue, but since systemctl reboot works, it seems like that would be less likely.

9

One more quickie. If your SDDM theme has changed, go to settings → startup and shutdown → Login screen (SDDM) → click on the behavior button on the bottom → the halt and reboot commands should be visible and pointing to systemctl shutdown and systemctl reboot.

I’m running out of ideas…

I can’t log out, poweroff, restart and logout are all unresponsive, only “switch user” and “lock” work and they don’t provide any power-related buttons.

I was using a custom SDDM theme but tried switching to both vanilla Breeze and Breath with no result. Global theme is already just ordinary Breath, but I will try switching and re-applying, maybe it helps?

Under SDDM - behaviour - halt and reboot everything looks fine:

/usr/bin/systemctl reboot
/usr/bin/systemctl poweroff

I suppose last chance is to try to switch global theme, but it seems doubtful.

What I find strange is that “switch user” and “lock” are working but not the other 3 alternatives. Do you know if these are connected to different things? Does SDDM handle the 3 options that do not work but not the other 2? Then maybe something with SDDM is broken? I never really understood the different login features available in Linux.

Edit: I checked my logs for errors and found the following which maybe be relevant:

org.kde.kdeconnect ICE default IO error handler doing an exit(), pid = 6674, errno = 2

systemd plasma-kactivitymanagerd.service: Failed with result ‘exit-code’

Edit 2: Never mind the above errors, unable to reproduce them so they seem to have been connected to that particular boot.

I also solved the issue with the buttons after a day of troubleshooting. The issue was quite ridiculous and not at all as deep as I had assumed. I realized that it had nothing to do with SDDM as both switch user and lock worked fine and at least “switch user” seems to drop me to SDDM. Restoring global theme also made the “switch user screen” look like it used to. Then I remembered that the restart and poweroff options do not put you in SDDM but rather some form of graphical overlay on the desktop.

For future reference this is what I did:

Settings - Startup and Shutdown - Desktop sessions - deselect “confirm logout” and “offer shutdown options” - apply. Now the buttons work. Next session after restart simply apply them again and the overlay works again.
