查看当前的调节器：
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
更改使用的调节器，需再更改scaling_governor文件（在sudo su条件下）：
echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

设置CPU的频率需要安装cpufrequtils,因此终端执行:
sudo apt-get install cpufrequtils查看cpu当前频率信息,终端执行:
sudo cpufreq-info设置模式,对应于{最省电（最低频率），用户控制，最高或最低，正常，最大性能} ,终端执行:
cpufreq-set -g {powersave, userspace, ondemand, conservative, performance}以上是wiki上的，我照做了，但是最后一步，cpufreq-set -g conservative就出错了，不管是否用sudo都不行，报错如下：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?
