20.04 从挂起唤醒后冻结

Question

我认为我的问题与已经问过的问题非常相似：

1. 从 18.04 升级后，20.04 挂起时崩溃
2. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1882917 - 我也厌倦了该用户尝试做的所有事情。
3. https://github.com/pop-os/pop/issues/1172 - POP OS 上发生了非常类似的情况。

我认为这是更深层次的东西，与内核有关。我使用的是 AMD Ryzen 7，此行为重现于：

• 乌班图20.04
• 乌班图21.04
• 流行操作系统20.04
• 软呢帽 34

一个运行没有问题的发行版：

• 深度20

我花了三天不眠之夜尝试设置我的新机器，从一个发行版跳到另一个发行版，并试图找到解决方案。

以下是一些有用的命令输出：

我还打开了全盘加密！

如果我可以提供任何其他信息来帮助解决此问题，请告诉我。

Answer 1

使固定

我也遇到了这个问题*，如果在我执行以下操作后得到解决：

1. 编辑/etc/default/grub

1. 使用例如 vim 打开：sudo vim /etc/default/grub

2. 添加amd_iommu=off到 的选项GRUB_CMDLINE_LINUX_DEFAULT。（对我来说，是GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"从一开始，以及GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=off"在编辑之后。）

2.更新grub

跑步sudo update-grub。

在本指南中找到它：https://itectec.com/ubuntu/ubuntu-ubuntu-18-04-crashes-freezes-after-sleep-suspend/

*我的问题

我在修复之前遇到的确切问题（如果有人有类似但不相同的问题）。

重现步骤

与提问者相同，不过您也可以通过简单地使屏幕进入睡眠（待机）状态而不是挂起计算机来触发它。

1. 点击ctrl+alt+L锁定屏幕。等待屏幕变黑。
2. 按任意键将其唤醒。

行为

当屏幕唤醒时，我可以看到锁定屏幕，但它被冻结了；密码字段中的插入符号没有像平常那样闪烁，并且来自鼠标或键盘的输入似乎确实做了任何事情。唯一的例外是REISUBalt+SysRq （在键入R, E, I, S, U,时按住B），它确实重新启动了机器。

Answer 2

该问题似乎与暂停相关。每当系统暂停时，它就会冻结，除了强制重新启动之外不响应任何操作。所以暂时禁用挂起功能就解决了这个问题。

• 禁用所有睡眠选项：

  sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
  

• 阻止系统在盖子向下时休眠：

  sudo vim /etc/systemd/logind.conf
  

  并添加/更新这三行：
