Kded

hi, a problem in my kde 3.3.2:
i've the process kded which is continuosly polling on the hard drive, so i can't apply any power mgmt policy on it.
If i kill kded all works fine.
What's kded and could i tell to kded to not to poll on the hard drive so frequently? or (better) tell it to never poll on it?
I red bug reports and seems someone is having the same problem with kde3.4 too, but only seems a configuration trouble.

http://bugs.kde.org/show_bug.cgi?id=103073

I also looked at ~/.kde/share/config/kdedrc: there's an update info line... what's it? can i try to comment it?? but another similar line is into kdeglobals...

Thank you
Alessandro

kded is a daemon for KDE functionality that does not need any GUI but needs to be present for other applications to use.

You can usually configure which plugins it loads in control center under KDE components -> services

Perhaps you have some plugin like the mount watcher running.

Thanks but i didn't solved:
i tried to stop ALL plugins but kded continues polling :(
i also found this interesting web page, and i tried disabling FAM (even if i don't want to disable it permanently) and adding these lines to ~/.kde/share/config/kdedrc config file:

[General]
# PollInterval=500
# NFSPollInterval=5000
# HostnamePollInterval=5000
CheckSycoca=false
CheckUpdates=false
CheckHostname=false

nothing solved :(
i don't know which are the default kded setting, but i think it's not possible to have a continuous hd access every few seconds only in a kde session!
In this case, how to apply a good power mgmt on a laptop to obtain the max power saving? I tried evaluating xfce desktop environment, and in an xfce session i can obtain the maximus power saving. However, i use kde since 2 years and i don't want to change to another DE.
I'm sure there would be a way to avoid this continuos hd polling... but howto... :rolleyes:?(

If any idea, please post it... ;)

Hmm, maybe it is one of the modules which load on demand.

You could check bugs.kde.org if this is a known bug or feature request.

Is it really gaining much battery duration?
I am a laptop user myself but I usually have other applications access the harddisk every few seconds, so constant spin down/spin up would cost much more.

Problem identified?

It seems that I had the same problem: The HD spinning up every 20 seconds.

Finally, I think I solved it by deactivating the KDE Battery Monitor!

Lateron I noticed that the bug has already been reported:
http://bugs.kde.org/show_bug.cgi?id=95751

Please check whether deactivating klaptop helps you as well and perhaps add comments/votes to that bugreport

RE: Problem identified?

Indeed, KLaptopDaemon is a nasty tool. It sucks your battery empty. To see the battery status in my panel I modified the KSysGuard kicker applet. It doesn't warn you for empty batteries, but it works.

Or use the new kpowersave which is a KDE frontend for powersaved

Even lets you change CPU frequency settings (if this is possible for you processor)
