笔记本电脑 ACPI 问题

我刚刚在我的华硕 n56vz 笔记本电脑上安装了 Ubuntu 17.10，遇到了几个问题。第一个问题与显示设置有关（我在另一篇文章中问过这个问题）。第二个问题与 ACPI 有关。日志文件中有很多 ACPI 错误，笔记本电脑无法重新启动或关闭，笔记本电脑在合上盖子时无法挂起，等等。

更新：我可以通过编辑 grub 文件来解决重启问题：

sudo gedit /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
sudo update-grub

更新：上述解决方案只需要几次重启就能发挥作用。

更新：请参阅下面的 ACPI 日志消息列表

答案1

通过将 Nouveau 显示驱动程序切换到 Nvidia 384.111 驱动程序，大多数 ACPI 问题都得到了解决。现在我可以毫无问题地重启和关闭笔记本电脑，尽管仍然有一些 ACPI 错误。
