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:
- 使用另一个键盘(Logitech MK120),不会发生冻结现象。
- 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。
- 使用不同的 USB,仍然会出现冻结的情况。
- 切换键盘布局,仍然会出现冻结的情况。
- 使用另一台计算机,冻结现象仍然发生。
- 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)
