我遇到过许多 Linux 发行版的一个奇怪问题，如果我锁定 PC 并在一段时间后重新打开，我的电脑将不会响应。硬盘活动 LED 似乎没有闪烁，屏幕一片漆黑。显示器处于睡眠模式，因为它没有检测到任何活动。我尝试移动鼠标并使用键盘，但同样，它不会响应。这很奇怪，因为有时鼠标底部的激光会像 PC 关闭一样关闭。我真的不知道如何找出问题所在。我试过使用 journalctl，但我不知道如何读取它。
编辑：这是输出lscpi

太棒了，我从来没有对笔记本电脑做出过如此错误的判断。这真是一台很酷的笔记本电脑！你遇到的问题是 NVIDIA 卡。我想到两件事：
- 安装当前的 NVIDIA 驱动程序（如果还没有安装）
- 确保您使用 uefi 启动（检查您的 bios 并可能重新安装）
由于我不知道您的笔记本电脑品牌，所以这可能是您的设备的电源管理 (acpi) 和卡本身之间的通信问题。为了找出原因，请尝试以下操作（如果两个建议都不起作用）：
/etc/default/grub以 sudo 身份使用编辑器打开。quiet splash用以下行替换quiet splash nomodeset- 然后执行
sudo update-grub。
这不应该是最终的解决方案，因为 nomodeset 只会破坏你的能源管理。如果它不起作用，我就没有主意了，如果它起作用，我们应该进一步调查……
