Hi,
Can anyone tell me is it possible to configure F31 to power down directly (without prompting) when the power button is pressed?
I can’t find any reference online.
Regards,
Owen.

Thank you Vitaliy for your reply, however it seems you misunderstood the question. I want the machine to shut down gracefully when I press the button.
I note some debate about this on the forums of another Linux flavour. Also, this behaviour is standard in ‘that other’ OS!
Obviously this is not a show stopper but I firmly believe that as I am the human, if I press a button I expect the machine to do what it’s told.
Looks like I’ll have to learn how to patch and rebuild if I want this functionality. Think I’ve come to Linux a little late. My enthusiasm for programming waned some time ago!
Regards,
Owen.
Oh…That is asks for confirmation, actually…
-
Also your can write a script:
#! /bin/bashsystemctl poweroff
chmod u+x script.sh-
and make a shortcut.
- Err... yes, needs sudo, sucks...
systemctl poweroff doesn’t need sudo here.
Indeed, if you issue this command:
gsettings get org.gnome.settings-daemon.plugins.power power-button-action
While in the GUI you see “Power Off”, it is actually “interactive”.
And the possible values are:
$ gsettings range org.gnome.settings-daemon.plugins.power power-button-action
'nothing'
'suspend'
'hibernate'
'interactive'
So, I guess, one thing to do could be to set to nothing and find a way to intercept (using dbus? acpi? udev? polling journalctl?) that the power button was pressed (indeed in journalctl you can see this line systemd-logind[1350]: Power key pressed. )
Sorry but I can’t be of more help.

Gnome devs about that decision (Sounds sane).

8 inhibitors listed.
First
Then
Set InhibitorsMax=0 in /etc/systemd/logind.conf.HandlePowerKey=poweroff is default
Setting PowerKeyIgnoreInhibited=yes instead of above is not working...
( 🤪️man logind.conf: "Low level inhibitor locks ("handle-power-key", "handle-suspend-key", "handle-hibernate-key", "handle-lid-switch"), are always honored, irrespective of this setting.")
Finally
Pressing power button causes shutdown -- without confirmation.
PS: Now, obvious question: Where is i am exhibit idiotic and dangerous behavior?
Disclaimer: If i were your, i'm rather use a custom shortcut!

I don’t understand: with these steps, power off without confirmation works or not?
(Take into account that as far as I can understand, gnome considers the power button as a media key, like volume up, and it is not in line with systemd?.. Well too complex for me).
Who says that it is idiotic? I agree that it is dangerous, because there are computers where it is too simple to hit the power button by accident.

- Power Button Action [Nothing]
- Set InhibitorsMax=0 in /etc/systemd/logind.conf.
- Works, if HandlePowerKey=poweroff is default
Just a PowerKeyIgnoreInhibited=yes is a wrong option.
PS: In dconf-editor:
org.gnome.settings-daemon.plugins.media-keys power-static [‘XF86PowerOff’]
Setting it to [‘’] gives me nothing.
Hi All,
Just wanted to say many thanks for all the feedback, much appreciated!
Owen.
