因此，当我输入正斜杠键时，整个系统会冻结几秒钟。这只发生在我的 Corsair K90 键盘上。

我目前得到的是：

  1. 使用另一个键盘（Logitech MK120），不会发生冻结现象。
  2. 使用 Ubuntu 和 Pop_os 时会发生冻结。Windows、Manjaro XFCE 和 Fedora 上不会发生这种情况。
  3. 使用不同的 USB，仍然会出现冻结的情况。
  4. 切换键盘布局，仍然会出现冻结的情况。
  5. 使用另一台计算机，冻结现象仍然发生。
  6. 两种键盘均采用 ABNT2 布局（巴西葡萄牙语）

因此，看起来冻结只发生在我的 Corsair K90 和基于 Ubuntu 的发行版上。

修改映射

使用我得到的命令xmodmap -pke | less：

...
keycode  97 = slash question slash question degree questiondown degree questiondown slash question degree questiondown
...

我尝试使用命令删除一些重复xmodmap -e "keycode 97 = slash question degree"，但没有帮助。

使用另一个键盘进行测试（Logitech MK120，无冻结）

输入“/asd”。此键盘似乎不会发生“MappingNotify 事件”，也不会发生冻结。

接下来我可以尝试什么来阻止 Corsair 键盘冻结？

答案1

引用 Corsair 论坛：https://forum.corsair.com/forums/topic/107444-unofficial-linux-osx-driver/

安装非官方驱动程序。（它可能会有帮助。）

答案2

我在 Fedora 37 上安装了瑞士布局 (QWERTZ) 的 Strix 键盘。反斜杠 (ALTGR+<) 也导致了类似的冻结。

禁用 NKRO（N 键翻转）解决了该问题（按 FN+PGUP 切换开/关）
