#StackBounty: #20.04 #power-management #shutdown #hibernate How to disable the behaviour of the power button on Ubuntu 20LTS

Bounty: 100

I disabled the power button on my desktop (pressing it did nothing, no shutdown, no hibernation/sleep, because my kids like it to press)
After I upgraded my ubuntu from 18LTS to 20LTS, the disabled power button behaviour does not work anymore. When it is pressed, it hibernates the PC.

Here are my current settings gsettings list-recursively org.gnome.settings-daemon.plugins.power

org.gnome.settings-daemon.plugins.power lid-close-ac-action 'suspend'
org.gnome.settings-daemon.plugins.power time-critical 300
