外部键盘重复按键 - lliiikkkkeee tttthhhhiiiiis

Question

每当我用外部 USB 键盘按下按钮时，它们就会被按下多次（如标题所示）。我的 Lenovo T460s 上的内置键盘工作正常。

\n\n

\n
• 从 USB 启动的 Live 发行版：同样的问题
\n
• 测试的内核：4.8.4，当前为 4.10.0-041000-generic
\n
• 更新了联想 BIOS/UEFI (1.22)
\n
• Ubuntu 16.04.02 LTS
\n
• 键盘：Coolermaster MasterKeys S（似乎适用于 Linux 上的其他人）
\n
• 其他 USB 键盘（罗技）工作正常
\n
• 尝试了所有 USB 端口（对接、直接）
\n
• 当我第一次插入键盘时它就起作用了。
\n
• 设置键盘设置以禁用键盘重复但没有成功
\n
• 当单击一次快速打字时，它仅输入一个字符

在 中出现两次但未完全出现是正常dmesg的xinput吗lsusb？难道是该设备被“安装”了两次，所以“第一个”设备和“第二个”设备发生了干扰？请帮助我找到原因，我失去了理智......很高兴提供更多日志。

Answer 1

这不是 Ubuntu 或操作系统的问题，简单的键盘重置就可以解决问题（手册没有告诉如何正确重置）请参阅此博客文章重置键盘（格式化自己）：

\n

\n

选项1：

\n

\n

• 拔下键盘

  \n
\n

• 按 FN+右 Alt

  \n
\n

• 重新插入键盘（同时按住 FN+右 Alt 键）

  \n
\n

\n

\xc3\x83 此选项应该使键盘返回到工厂\n设置/演示模式。

\n

选项2：

\n

\n

• 保持键盘插入电脑

  \n
\n

• 按 FN+E 约 3 至 5 秒

  \n
\n

\n

\xc3\x83 此选项将清除键盘板载内存
