Dear F1ash!
Thank You very much indeed!
I really need a workable non-console utility to change cpu frequency for KDE 4 OpenSuse 13.1. And I was searching it for a long time. I tried applets for cpufrequtils that do not work in my system or adjust only one core like CpuFreqTray-0.9. But Your plasmoid is not only workable for all cores. Your plasmaCpuFreqUtility is the best from all cpu frequency regulators that I can find. It even has a very useful autorun option. The best functional and the best design of cpu regulators that I have ever seen. Now my notebook can be not so hot.
Thank You very much indeed!

Good plasmoid! Just what I need! But... could be possible to change all CPU governors wth only one move? I mean set all cpu governors to conservative (for exameple) at same time, not going one by one.

OK, I'm sorry. I see this option now. Thanks again!

I'm fine. Maybe you forgot to install the kdelibs5-dev package?

Thanks, that solved the compiling problem but now when I add the plamoid to my kde panel I get a warning that says "KAuth returned an error code: 3" twice and when I click on the plasmoid icon it shows a red "ERROR" message.

This occurs when an error reading\writing (as I understand, your comp have two core). It is likely that the rules for polkit not been applied. Relogin user.

I like this plasmoid very much, but what I found is that once I disable a CPU, there is no way to get it enabled again. The line with the disabled CPU is not showing anymore.

I can not reproduce this bug. Try to find errors in the file ~/.xsession-errors .

Hi,

I installed the plasmoid from the kde-files service on my debian-sid machine. It says twice:
KAuth returned an error code: 3
and then appears the square orange button that says "error" when pressed.

I haven't compiled nothing, just installed from plasma service.

In Fedora the compile requires is gcc-c++ & kdelibs-devel packages.
In Ubuntu : kdelibs5-dev ( https://github.com/F1ash/plasmaCpuFreqUtility/issues/1 ).
In Debian : I don`t know. It`s may be kdelibs5-dev or similar.

I don't understand why does it need compiling, being python.

Besides, I think it's wrong to let install a plasmoid without making the user aware of the missing packages or automatically installing them.
Also, installing kdelibs-dev requires tens dependencies of dev-packages. All that stuff for a plasmoid? Isn't there any better way? Why the other plasmoids don't need compiling and all that dependecies?

thanks

Part of the code written in C++ (no other way). It is therefore necessary compiling, and this requires a similar package kdelibs-devel.
You can write a spec for Debian, and I will add it.

Hi guys,
I'm still having this problem:

This object could not be created for the following reason:
Can't open the package kde-plasma-cpufrequtility requested by the object CPUFreq Utility.

I have read the answers above,but I cannot find out how to make it work...I'm using Arch Linux...Has anyone made it to work...
Btw thank you about this really useful plasmoid...

//sorry about my poot English...

Unfortunately, I can not test on Arch. Then for Arch needs to rewrite some parts of the plasmoid.

Hi

Thanks for what looks like a great plasmoid.

Hi,

Has the code been updated it looks like I'm getting the same errors. I have a 6 core CPU.

Try to sure that a code changed in path:
/usr/share/kde4/apps/plasma/plasmoids/kde-plasma-cpufrequtility/contents/code/main.py

now in line 98-99 :
procData['online'] = {}
for i in present : procData['online'][int(i)] = readCpuData(str(i), 'online')

If code is changed, but a bug is stay, then I will make the debug-version for you.
