我在用Ubuntu 18.04.2 索尼 Vaio。
我合上盖子并尝试重新启动操作系统后，键盘没有响应。
以下是输出dmesg | grep i8042

答案1
我最近遇到了这个奇怪的问题（我的笔记本电脑也是索尼 Vaio）。我只需按下背面 Vaio 徽标下方的按钮（按钮在一块塑料下面）即可关闭笔记本电脑（您也可以等待电池耗尽）。重新启动后，问题就解决了。
答案2
我在运行 Pop!_OS 19.04（基于 Ubuntu）的现代 System76 Darter Pro 上也遇到了这个问题。System76 支持人员也遇到了这个错误。重新挂起和重新恢复有帮助吗？
恢复后，我收到 dmesg：
i8042: failed to resume active multiplexor, mouse won't work
重新挂起笔记本电脑然后再次恢复可以解决这个问题。只有当我运行 linux-lowlatency 内核（启用 rtirq）时，它才会对我产生影响。我还没有能够在 linux-generic 上重现（就我所知/记忆而言）。
答案3
我也遇到过这个问题，但是这个脚本似乎解决了这个问题。
