Power button triggers does nothing after Plasma 6.8

Hello!
I upgraded to plasma 6.8 like 2 hrs ago, It was a massive upgrade and everything seemed okay.
But when I press the power button nothing happens, the global shortcuts are cleared too.
I did the EVTest for power button but no avail.
Can someone guide me to this.

Re: Power button triggers does nothing after Plasma 6.8

Please use [code][/code] tags.

Did you reboot after the update?
(Or at least re-login)

the global shortcuts are cleared too.

printenv
qdbus6

Yes I did reboot, relogin , created new profile to check if its working there or not, but no avail.
Its not getting detected at all, checked the shortcuts and try to set it but its not taking the power button -> like nothing happens.

Re: Power button triggers does nothing after Plasma 6.8

The idea was that you post the output of the two commands.

On a formal note, please avoid bloating the thread w/ unmotivated full quotes.

Edit: plasma might be innocent, try to downgrade the kernel

Re: Power button triggers does nothing after Plasma 6.8

Edit: plasma might be innocent, try to downgrade the kernel

I checked the thread you added, and as you say downgrading might help me too, but is there hope if I wait for an bug fix update or something like that?
Also will the downgrade cause any problems?
Thanks

Re: Power button triggers does nothing after Plasma 6.8

No. The kernel is pretty much self-contained and unless you're trying to use ancient precompiled ones you're extremely unlikely to run into issues (just keep in mind that optional headers and/or out-of-tree module packages must be downgraded accordingly)

Environment looks harmless and org.kde.kglobalaccel is registered, so you want to see whether this came from the kernel (in particular if global shortcuts like win+l or so still work)

Ah Okay, and yes all other shortcuts works like ctrl+alt+del and win+I
Also how do I safely downgrade?

Re: Power button triggers does nothing after Plasma 6.8

I had the same problem. It is not related to kde. I downgraded to 6.18.56 and fixed the issue.

Hello!
I upgraded to plasma 6.8 like 2 hrs ago, It was a massive upgrade and everything seemed okay.
But when I press the power button nothing happens, the global shortcuts are cleared too.
I did the EVTest for power button but no avail.
Can someone guide me to this.
