Ubuntu 14.04 笔记本电脑键盘不起作用

我有一台装有 Ubuntu 14.04 的 Acer Aspire ES1-131-C77V。有一天键盘停止工作了。它只在 BIOS 和 GRUB 中工作。它在操作系统、恢复模式甚至 LiveCD 中都不起作用。最奇怪的是 FN + 左/右箭头工作正常，直到我按下任何其他键。USB 键盘工作正常。

lsusb 的输出

Bus 001 Device 003: ID 0bda:57b3 Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

根据那些人的说法，可能是代码页问题

类型

locale=en_EN i8042.reset

在 grubs 内核行的末尾

  • 当出现 grub 菜单时，选择 linux 操作系统 > 按“e” > 转到内核行的末尾并编辑 > 按“b”启动

  • 或在操作系统加载后 > 终端 > nano /etc/default/grub > GRUB_CMDLINE_LINUX="quiet splash locale=en_EN i8042.reset" > update-grub
