Re: [Trisquel-users] [ACPI] Disabling power button handling?

[infinityfallen]

I would suspect your guess is correct. Trisquel 7 Mini uses systemd- which  
takes over handling that sort of thing. As such, according to the last answer  
at  
https://superuser.com/questions/699905/change-behavior-of-linux-power-button,  
all you need to do is add the following line to /etc/systemd/logind.conf:
HandlePowerKey=ignore
Then reboot, and (hopefully) the power button should stop responding to short  
presses. Long presses will still kill the system, but I presume that's not an  
issue.
