Powertop自动图腾错误-无法从文件中加载

Question

我正在尝试执行--在powertop中进行自动调优，但是我得到了以下错误

无法从文件/var/cache/powertop/已保存的参数s.powertop加载

如果我浏览到该目录，该文件确实存在。

我从跑步开始--先校准一下，这样就完成了。

这是完整的打印出来；

Answer 1

这是正常的。你可以看到File will be loaded after taking minimum number of measurement(s) with battery only的解释。

过了一段时间，这个警告就会消失。

Answer 2

运行sudo powertop一段时间，计数器将达到0
