I can confirm that systemd logind is in control of the power button on my ASUS UX305 laptop as of Kubuntu 15.04. This means that no matter what the settings in KDE system-settings the power button is handled by logind.
Since the power button is right above backspace and I often hit the backspace key (and have accidentally shut off my laptop several times) I have changed the line in /etc/systemd/logind.conf to: HandlePowerKey=ignore This renders the power key useless, but that is better then accidentally shutting my computer off in the middle of typing. If logind is going to "handle" the power key, maybe system-settings should deal with logind and not acpi or whatever else system-settings is trying modify to get configuration control of the power key? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1201180 Title: powerbtn.sh conflicts with logind Status in acpid package in Ubuntu: Fix Released Status in gnome-session package in Ubuntu: Fix Released Status in kde-workspace package in Ubuntu: Triaged Status in systemd package in Ubuntu: Fix Released Status in systemd-shim package in Ubuntu: Invalid Bug description: In saucy the PC powers down as soon as I press the power button, it seems that systemd is calling "poweroff", but I'm not sure if it's doing that in response of some other event (i.e. as callback of a dbus call): root 4998 0.0 0.0 177932 2104 ?
