cpufreq-set -g performance does nothing

Hello again smile

as the topic tells, sudo cpufreq-set -g performance has absolutly no effect, I am stucked at 800mhz (cpufreq-info) although I loaded everything in rc.conf. 

MODULES=(e1000e pcspkr snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd snd-pcsp snd-hda-codec snd-hda-intel soundcore acpi-cpufreq cpufreq_ondemand cpufreq_powersave cpufreq_userspace).

Any ideas? It worked a few days ago when I set my box up but now it simply stoped working.

Regards, tealson

So, sudo cpufreq-info tells me I'm running at 2.53 and without sudo I'm running at 800mhz? Sorry for the german language output, my arch does it by default wink

Re: cpufreq-set -g performance does nothing

I see that both outputs sais you are running at 2,53GHz

momentane Taktfrequenz ist 2.53 GHz

so whats the problem? smile

EDIT May, 14, 18:22

What is output if you try to use

sudo cpufreq-set -g performance

Passt schon wink

You can tell your terminal to output english texts by this line

export LANG=C

Afterwards it'll all be english

Re: cpufreq-set -g performance does nothing

Well the problem is, why are 2 different core frequencies reported?
Would be fine to do the clock settings as user though...

ps: Thanks Army wink

Re: cpufreq-set -g performance does nothing

tealson I do not know if we see different log, but could you tell me where in the log which you send here is the differentce showing that you are at 800MHz? (I just do not see reported two different frequencies)

you cou use

sudo visudo

and add there a line

%users ALL=(ALL) NOPASSWD: /usr/bin/cpufreq-set

all the user with this line should get power to use "cpufreq-set" without running "sudo"

Re: cpufreq-set -g performance does nothing

Thanks, i'll give visudo a try right away.

Here is the log, I posted the wrong version sorry for this.

This is done by a normal user, the first output is 2.53, the second is 800mhz. This cannot be because both cores can only be clocked at the same speed!

ps: the output is still in german, sorry folks! smile

Re: cpufreq-set -g performance does nothing

I had this problem when trying to set cpufreq to lower speed. Turns out that cpufreq-set -g governor sets only for one core (a bug or a feature?)
So I now use:

[root@lightbringer dheart]# cpufreq-set -g powersave -c 0
[root@lightbringer dheart]# cpufreq-set -g powersave -c 1

-c NUMBER represents the desired cpu.
You should try this.

My victim you are meant to be
No, you cannot hide nor flee
You know what I'm looking for
Pleasure your torture, I will endure...
