To do this, I wrote a script:


cpufreq-set -c 0 -u 1000MHz
cpufreq-set -c 1 -u 1000MHz

This script, executed with root permissions, is setting the cpu frequency to
But after some time, suddenly the frequency is up to 1,67 GHz again. IMHO only
an application like kmail or anything else might change this.

Is there something known about?  Is this a bug?

I use cpufreq to adjust the governor, and it seems to work:

# cat cpufreq-set-ondemand.sh
cpufreq-set -g ondemand

2017-02-09 12:43:17 root@cd2533 ~/home
# cat cpufreq-set-performance.sh
cpufreq-set -g performance

2017-02-09 12:43:25 root@cd2533 ~/home
# cat cpufreq-set-powersave.sh
cpufreq-set -g powersave
