我无法暂停 Ubuntu，我想是自上次更新以来（我认为安装了内核 5.13.0-37）。当我按下关机或暂停按钮，或通过菜单选择任一按钮时，我的系统会注销而不是执行相应的操作，并将我带到启动屏幕。没有其他用户登录。
我到目前为止尝试过但没有帮助的方法：
- 清除 NVIDIA 驱动程序。
- 尝试使用 GRUB 中安装的另一个内核：5.13.0-35。
- 安装了 20.04 的最新 GA 内核：5.4.187。

根据同事的建议，我检查了一些 NVIDIA 链接systemd，发现它们确实坏了：
$ ls /etc/systemd/system/systemd-*/*
/etc/systemd/system/systemd-hibernate.service.requires/nvidia-hibernate.service
/etc/systemd/system/systemd-hibernate.service.requires/nvidia-resume.service
/etc/systemd/system/systemd-suspend.service.requires/nvidia-resume.service
/etc/systemd/system/systemd-suspend.service.requires/nvidia-suspend.service
解决这个问题的方法是删除它们，根据栅栏状‘回答在此相关主题中： Ubuntu 20.04 暂停注销并唤醒
