系统偶尔不会暂停

  • 772

我的系统时不时无法正常挂起。关闭盖子、选择从图形界面挂起或运行命令都会关闭屏幕，但系统会在几秒钟后重新启动。运行故障排除显示某些设备阻止系统挂起。如何才能让我的系统挂起？

suspend

    可能是某个特定设备阻止了您的系统挂起，因此几秒钟后系统会再次启动。为了避免这种情况，请尝试禁用一些可能导致唤醒的设备，以便您的系统可以正常挂起。

    以下是我的情况：

    1. echo mem | sudo tee /sys/power/state尝试暂停（也可以以root 身份运行命令）
    2. 以 root身份运行journalctl -b。
    3. 识别表示设备阻止系统关闭的条目。在我的例子中，有问题的输出是这样的：

    1. 搜索可以唤醒设备的设备，或者，由于这个错误，可能会阻止设备挂起。为此，请查看 的内容/proc/acpi/wakeup（例如使用cat /proc/acpi/wakeup）。您应该会得到一个设备列表，其中一些设备发出disabled信号表示它们无法唤醒您的机器，其他设备则发出信号enabled。我的文件如下所示：

    1. 将阻止挂起的设备的输出与设备列表进行比较。如果有任何标识符指向 的设备enable，请考虑disabling它们。为此，请以 root 身份编辑文本文件，并将此特定设备 替换为disabled。enabled（我对 进行了替换HDAS）。
    2. 尝试暂停你的机器。

    奖励： 要了解阻止挂起的设备，请lspci以 root 身份运行。

    就我而言，我得到：

    有问题的设备是00:1f.6，我得出的结论是以太网控制器阻止了系统暂停。

    注意：当然还有其他问题导致无法暂停系统。这只是旨在补充现有解释的贡献。
