Решил поменять схему энергопотребления процессора:
Код: Выделить всё

performance powersave

Код: Выделить всё
MyHome1 pastordi # cpupower frequency-set -g ondemand
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?

Под root'ом ничего сделать нельзя. Хм... Или я чёта туплю?
Ядро 3.14.33
мне не нужно "как надо", мне нужно ondemand.
cpupower не стартует, режим по умолчанию стоит powersave.
Ладно, оставлю его пока.
