Hello,

Since KDE 4.4 (Mandriva distro), I'm no longer able to change power saving schemes, like 'performance', 'xtreme powersave' ..., using the battery indicator plasmoid. Moreover, plugging/unplugging doesn't change the power saving scheme at all.

Is it a known problem with KDE 4.4 ? It was fine in KDE 4.3. Is there a fix ?

Thank you.

Please post the output of the following command:

Code: Select all

qdbus org.kde.kded /kded loadedModules

Thank you for your reply.

Here's the output :

networkstatus
remotedirnotify
kephal
favicons
nepomuksearchmodule
khotkeys
dnssdwatcher
solidautoeject
ksvnd
randrmonitor
kwrited
networkwatcher
konqy_preloader
freespacenotifier
desktopnotifier
ktimezoned
kcookiejar
kpasswdserver

I made a quick comparison with the output from another installation with KDE 4.3, it seems t be missing powerdevil namely.

Please suggest a fix if any.

What is the output of "qdbus org.kde.kded /kded loadModule powerdevil"?

Also check in System Settings > ... > Service Manager to ensure PowerDevil is enabled.

qdbus org.kde.kded /kded loadModule powerdevil

does load the powerdevil module and restores expected behaviour.

System Settings > ... > Service Manager / PowerDevil is enabled but does not start up after logging.

Code: Select all

qdbus org.kde.kded /kded isModuleAutoloaded powerdevil

returns true, even if it does not get loaded.

Code: Select all

qdbus org.kde.kded /kded setModuleAutoloading powerdevil true

doesn't cure the problem.

I ended up loading the powerdevil module in a script run upon KDE start.

Thank you very much for your help.
