我的 Ubuntu 笔记本电脑（华硕 K501UX，Ubuntu 16.04 LTS）在合上盖子并重新打开后死机。屏幕变黑，没有鼠标或任何东西——我唯一能做的就是按 Alt-SysReq- R/E/I/S/U/B 强制重启。我无法按 Ctrl-Alt-F1。
我有一台 GeForce GTX 950M，NVIDIA 驱动程序为 nvidia-384。Nouveau 被列入黑名单，因为我必须在这台机器上设置 Cuda。我的显示管理器是 lightdm。
我尝试了多种解决方案（使用特殊启动选项或安装 xscreensaver，例如暂停后键盘和鼠标无响应)，但没有成功。
以下是我重新启动之前操作过程中 /var/log/syslog 中发生的情况：
