Power management -hardware settings missing - KDE Neon

Hi all,

I’m running the latest build of Neon, with all applicable updates through pkcon, apt and discover.

There’s no hardware section of my settings menu, nor is there a search result for sleep, hibernate or power, besides monitor sleep settings.

I’m sure there’s probably a config file I need to edit (already tried sleep.conf in etc/systemd, to no avail, after a rudimentary search)

Does anyone have any ideas where best to look? I don’t want to blindly edit config files and break something down the line.

Looking to set a sleep timer for an hour past last input, excluding VLC/media/YouTube playback, as it’s a media/gaming machine for the TV

Resolved, powerdevil was missing, a reboot later after installing it seemed to have worked.

I can now successfully set power options based on inactivity
