想搞这个很久了，一直不会搞，今天看了 qinqin 的帖子才知道怎么做。

装好了那个啥，结果出来这个：

analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU

这样就好了：

sudo modprobe -a acpi-cpufreq

很好很节能。

$ cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 0
  hardware limits: 2.00 GHz - 2.33 GHz
  available frequency steps: 2.33 GHz, 2.00 GHz
  available cpufreq governors: powersave, userspace, ondemand, conservative, performance
  current policy: frequency should be within 2.00 GHz and 2.33 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 2.00 GHz.
analyzing CPU 1:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 1
  hardware limits: 2.00 GHz - 2.33 GHz
  available frequency steps: 2.33 GHz, 2.00 GHz
  available cpufreq governors: powersave, userspace, ondemand, conservative, performance
  current policy: frequency should be within 2.00 GHz and 2.33 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 2.00 GHz.

PS：为什么电费要在星期一才能交呢。
