IBUS修改输入法和设置切换快捷键

### 1. 安装libpinyin

```
sudo apt install ibus-libpinyin
```

### 2. 设置默认输入法引擎

通过 `gsettings set` 命令直接指定预加载的输入法引擎（如智能拼音）：

```bash
# 设置默认预加载引擎（智能拼音）
gsettings set org.freedesktop.ibus.general preload-engines "['libpinyin', 'xkb:us::eng']"

# 设置引擎顺序（优先级）
gsettings set org.freedesktop.ibus.general engines-order "['libpinyin', 'xkb:us::eng']"
```

此操作将智能拼音设为默认输入法，英文键盘为备用输入法

### 3. 查看 gsettings 中 libpinyin 支持的相关键值

```

```

### 4. 修改切换快捷键为 Ctrl

```bash
gsettings set com.github.libpinyin.ibus-libpinyin.libpinyin main-switch  '<Control>'
```

若 `Control` 键与其他应用快捷键冲突（如终端中的 `Ctrl+C` 中断命令），建议改用组合键（如 `Ctrl+Space`）

```bash
gsettings set com.github.libpinyin.ibus-libpinyin.libbopomofo main-switch '<Control>space'
```

### 5. 重启IBus服务

根据情况可重启IBus输入法框架

```bash
ibus-daemon -drx
```
