kde 4.5.3 power management profiles missing

[fedor]

Hi,

I have a problem with kde power management after upgrading to 4.5.3 from 4.4.3.
Note that, to be sure, I deleted former .kde4 directory and .config/Trolltech,conf as well.

I noticed that in "System settings/Power Management/Edit Profiles" there are only three profiles (Aggressive Powersave and Extreme Powersave missing). This is not so bad because you can add as many profiles as you wish so I could create them from scratch. But, in the "CPU and System" tab I cannot select cpu power profile anymore (such as "ondemand" or "performance").
Furthermore I noticed that in the "Capabilities" tab some lines are missing now...

What can I do?

Thanks in advance...

Maybe I found the answer by myself:
in the Ark Wiki I can read that cpufreq capabilities have been removed starting from kde 4.5.x!
Honestly, I don't understand: while ondemand profile should be reliable by now, I always want to be in the place to choose to sacrifice performance to the benefit of power saving.
So, I put these commands in the "When loading profile execute" field of my powersaving profiles:

/usr/bin/solid-powermanagement set cpufreq powersave

And this one for the performance profiles:

/usr/bin/solid-powermanagement set cpufreq ondemand

Maybe in the real life the difference is not that noticeable but I think Linux is about control...and I want to be in control here...

Interesting:
I noted the problem too, mainly the lack of "ondemand", I thought it was a personal problem...

thanks for investigate into the problem and for the solution, hoping that next KDE 4.5.4 would solve natively the problem

bye, NicCo

and here, maybe, the rationale behind the kde group choice:
