我正在尝试改变键盘，以便通过输入 AltGr（右 Alt）+ u 会出现 ü 键。
添加了 /usr/share/X11/xkb/symbols/us
键 { [ u, U, udiaeresis, Udiaeresis ] };
Ubuntu 似乎识别它：
但如果同时按下右 alt 和 u 键，则不会发生任何反应。知道缺少什么吗？我尝试调整组合键设置，但没有帮助。
答案1
解决方案是使用
github.com/SnakeJesus/Umlaute-on-US-layout
似乎还需要定义 AltGr 键（参见 Gunnar Hjalmarsson 的评论）：
包括“level3（ralt_switch）”
答案2
x11/xmodmap 不适用于 Wayland。Wayland 使用 xkb
所以有两种方法
1. 使用 x11/xmodmap
第一：在启动登录时设置 x11 上的 ubuntu
在登录时选择“x11”而不是“wayland”。您可以在登录时单击右下角的按钮来执行此操作。
显示哪种键盘布局：
如果setxkbmap -print -verbose 10仅显示
...
layout: us
...
.Xmodmap 上的更改没有效果。
设置正确的国际键盘
setxkbmap -layout 'us(intl)'
必将导致
setxkbmap -print -verbose 10
Setting verbose level to 10
locale is C

Trying to load rules file /usr/share/X11/xkb/rules/evdev...
Success.
Applied rules from evdev:
rules: evdev
model: pc105
layout: us(intl)
Trying to build keymap using the following components:
keycodes: evdev+aliases(qwerty)
types: complete
compat: complete
symbols: pc+us(intl)+inet(evdev)
geometry: pc(pc105)
xkb_keymap {
xkb_keycodes { include "evdev+aliases(qwerty)" };
xkb_types { include "complete" };
xkb_compat { include "complete" };
xkb_symbols { include "pc+us(intl)+inet(evdev)" };
xkb_geometry { include "pc(pc105)" };
};
设置 .Xmodmap
例子：
- 使用修改后的 .Xmodmap
