power managment not working under lxqt mga5RC (solved)

[wintpe]

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

Just read this again, and now it struck me - this basically works as designed. You're trying to use KDE power management daemon/tools in an LXQt session.
That means you would have to also start a KDE session when you login to LXQt. At least kded4 and powerdevil would have to be started.
You would have to add that to LXQt autostart, simple as that. Sorry but that is not an LXQt issue.

thats a shame, as when kde does the power managment in this way, it works.
lxqt power managment, pretty much does nothing.

ps ill try and find a way.

What do you mean in particular by "when kde does the power managment in this way, it works."
What do you miss or expect from lxqt power management, what does it not do currently?

Your best bet is to search through the open issues/feature requests in https://github.com/lxde/lxqt/issues
and add a new one what you think should be added.

FWIW there are already some open issues regarding power management:

I don't get it too it works to me out of box have no any problems.

[wintpe]

maybe that was not a helpful reply of mine.

ok lxqt power management, does little as far as i can see, in other words is featureless.

it has watchers but thats about it, that blank the screen when not in use, or shutdown when low on power.

but there's no active power management for energy saving.

kde power management is significantly more feature rich.

You can always add it manually to autostart or start kde session at lxqt start.

thats what ive been trying to get to the bottom of.

and struggling with.

I cant get kde powerdevil to start running.

That means you would have to also start a KDE session when you login to LXQt. At least kded4 and powerdevil would have to be started.

It should be possible to start it via script or in foreground as a test

Code: Select all

kded4; disown

[wintpe]

Code: Select all

[peter@localhost ~]$ kded4; disown
KDE Daemon (kded) already running.
bash: disown: current: no such job
[peter@localhost ~]$

I use kwin as my window manager in lxqt, so its already running.

Try this i get it from kde forum.

Code: Select all

qdbus org.kde.kded /kded loadModule powerdevil

[wintpe]

Yay......

add an autostart in lxqt settings with the line

qdbus org.kde.kded /kded loadModule powerdevil

problem fixed

thank you ozky
