我在 Ubuntu 上使用蓝牙触摸鼠标，注意到它有一些额外的键盘映射，对我来说没有实际用途。向左滑动鼠标会产生“d”，向右滑动会产生退格键。我尝试使用 xinput 和 input-kdb 更改键映射，但到目前为止没有任何运气。
$ xinput list "ThinkPad Bluetooth Touch Mouse"

禁用按钮没有帮助（将它们映射到 0），仍然会生成各种字符。
使用input-kbd更改键映射会导致错误。
$ sudo input-kbd 6

创建一个将0x70007 = 240d 映射到的文件KEY_UNKNOWN会导致
$ sudo input-kdb -f keymap 6

是否有另一种方法可以以某种方式映射这些源自鼠标的键盘输入？
