Disable ACPI power button = shutdown host?

[luckman212]

Hi,
I'm new to Proxmox and just getting started with a couple of small homelab machines (Intel NUCs)

One thing I noticed right away (quite by accident) was that if someone merely bumps the front panel power button (ACPI) - the Proxmox host will immediately and without any confirmation just initiate a shutdown sequence!

I'd like to disable this or at very least, require holding the button for >4 seconds etc. to prevent accidental shutdowns.

Is this possible? I searched a bit and found nothing - so please forgive me if this is a simple/stupid question

You can edit the file '/etc/systemd/logind.conf' and set 'HandlePowerKey' to 'ignore'.

Wow this is great, thank you - I will try it today

Cool, found this by searching for how to do it, which service needs to be restarted to changes to take effect, if any?

 

[Stefan_R]

systemctl daemon-reload
systemctl restart systemd-logind.service

should do the trick (note that this will log you out), or just reboot.

Thanks. And it did not even log me out

it doesn't work. Proxmox still shutdown when i press power button.
