Wolna praca ubuntu 14.04 LTS na HP 8540W

[kenpo]

U mnie pojawiły się tylko trzy kroki. Poza tym najwyższy to 2.67 GHz. Zastanawiam się dlaczego nie 2.80GHz.
Robiłem to tak:

Kod: [Zaznacz]

sudo apt-get install install cpufrequtils

sudo nano /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
