这个问题已经困扰我一段时间了。我有一台运行 Ubuntu 10.04 的小型上网本。它时不时地会进入待机状态，关闭屏幕，降低磁盘转速，暂停约 10 秒钟，然后敲击键盘后再次唤醒并提示输入密码。只要我输入密码，一切都会从中断的地方恢复正常，这就是我确信它正在进入待机状态的原因。
但是，我似乎无法根据症状确定待机的原因。Coretemp 和其他温度实用程序不会报告高温（通常低于 30C），GNOME 电源首选项面板根本没有设置为待机，而且据我所知，我的内存运行良好，没有被过度使用。
我被难住了。在日志和/或设置中开始诊断此问题的最佳方法是什么。我在其他 Ubuntu 10.04 安装中从未遇到过此问题，并且我运行了一个满是此类设备的实验室，因此我认为这与笔记本电脑有关。
我的模块在启动时加载（/etc/modules）：
lp
battery
ac
thermal
processor
acpi-cpufreq
cpufreq-userspace
coretemp
干杯!

答案1
在这种情况下，我会确保我可以从另一台计算机通过 SSH 进入上网本。在上网本靠近且可见的情况下，在第二台计算机上运行命令top并密切监视输出，以便当上网本进入待机状态时，您将看到执行了哪些命令/应用程序。从那里您可以进一步解决问题。
