OK i know how to make power management work, but ive not yet managed to make it stick.
heres the problem, in an lxqt session using kwin as wm
go into kde settings and select power management , but its disabled.
it gives you a hint to ensure that power management is started in start up and shutdown services manager.
so start it and power management appears to be available.
but it wont stay started, how do you make it stay?
IE it wont survive a reboot
