因此，我查看了一些有关 Ubuntu 16.04 中键盘崩溃的其他帖子，但它们似乎没有我遇到的完全相同的问题。
我的情况很有趣，因为键盘崩溃了，而且只有键盘崩溃了。鼠标仍然可以移动光标，左键单击/右键单击仍然可以执行预期的操作。额外的好处是，当这种情况发生时，我必须强制重启。正常重启会无限期挂起，迫使我按住电源按钮。
我的系统是联想 Ideapad，配备 i7 四核处理器、Nvidia 专用显卡、12GB 内存、M2 SSD 和 Sata SSD。

在 Windows 中更新联想 BIOS
幸运的是，您仍在第二个 SSD 上安装了 Windows（/dev/sdb），因此您仍然可以将 BIOS 更新应用到您的笔记本电脑。许多用户报告说 BIOS 错误导致键盘冻结。解决方案只能通过 Windows 应用，而且似乎没有 Linux BIOS 更新对于该错误。
更新 Linux 的 Intel 微代码
当您遇到问题时，在 Ubuntu / Linux 中获取最新的英特尔微码是一个好主意：
从 Ubuntu 软件设置中，选中底部选项英特尔微码以便在下次启动时启用支持。
返回旧内核或获取最新的 4.14.xx 内核
许多 Ubuntu 用户报告了与 2018 年初匆忙发布的 Meltdown 补丁有关的问题，导致内核 4.10.0-42 用户提前升级到内核 4.13.0-26。
您可以阅读更多这里。
