how disable power management in terminal?

[Vim]

How can I disable Kubuntu's power management from a command line?
I've searched online for hours, without finding an answer to this question.

I should have mentioned in my previous post that I'm using Kubuntu 12.04 LTS.

(The forum software thinks I'm using Ubuntu 8.04. (I tried to update my profile but the forum software said: "Vim, you do not have permission to access this page. This could be due to one of several reasons: Your user account has less than 50 posts. ...(etc)".))

I have the same question!
The only variant I learned is here http://forum.kde.org/viewtopic.php?f=22&t=37365

Briefly, you are to change
X-KDE-Kded-phase=1
to
X-KDE-Kded-phase=0
in /usr/share/kde4/services/kded/powerdevil.desktop

and then to start
$ kded4

May be there is an easier way?
