hI,
After installing minimal Sparky 4.3.0, I dist-upgraded the system (openbox) to 4.4.0-1-amd64. My laptop is lenovo with i5 4200 processor.
When booting using kernel 4.4.0-1 cpu frequency is about 700 MHZ ,is not scalled and remind so despite running different applications.
When booting 4.3.0 it is properly scaled 0.8 to 3.1 GHz. I see it using - watch grep \"cpu MHz\" /proc/cpuinfo.
Did the same on bare debian. It is similar.
What I'm doing wrong?
Greetings from germany
try to install the cpufrequtils the way you want to... and after that
try cpufreq-info
and check which governor is activated....
the governor by default should be "on demand" ... maybe you are
on powersave... so the cpu can't speed up... :-[

I think the problem was specific to lenovo i5. With next kernel frequency adopts to workload as needed.
Thanks seonine for replay & greetings
