如何让普通用户获得足够权限运行cpufreq-set ？

1. 
   
2. $ cpufreq-set -g ondemand
   
3. Error setting new values. Common errors:
   
4. - Do you have proper administration rights? (super-user?)
   
5. - Is the governor you requested available and modprobed?
   
6. - Trying to set an invalid policy?
   
7. - Trying to set a specific frequency, but userspace governor is not available,
   
8.    for example because of hardware which cannot be set to a specific frequency
   
9.    or because the userspace governor isn't loaded?

visudo编辑一下，添加这项到NOPASSWD那行可以不

不知道为什么要这么做呢？

当sensors-applet 或 ksensors 检测到 CPU 温度
达到温度53的时候就会执行
cpufreq-set -f 1800000
当降了后仍然达到更高的温度55的时候
cpufreq-set -f 1000000
当温度下降到38以下时，又恢复ondemand状态
cpufreq-set -g ondemand

还有，gentoo的cpufreq-selector默认给了普通用户权限，但cpufreq-selector是gnome-applets附送的。可是现在换了口味用kde 4.2.4 ，只好用 cpufreq-set 。

debian的cpufreq-selector默认普通用户不能调，但是可以通过dpkg-reconfigure gnome-applets 开关这个权限。

我还想问gentoo怎么关闭cpufreq-selector的普通用户权限呢？
