evdev ButtonMapping 记录正常但没有效果

忽略命令有效，但按钮映射无效。

我创建了一个文件/usr/share/X11/xorg.conf.d/39-myinput.com：

Section "InputClass"
        Identifier "Apple MagicKeyboard"
        MatchIsKeyboard "on"
        MatchProduct "Magic Keyboard"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "Ignore" "off"
        Option "ButtonMapping" "1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 0"
EndSection

我目前正在测试 ButtonMapping，但似乎没有效果。您能给我指明正确的方向吗？

我已evtest确定键 16 和 17 是Q和 W：

Event: time 1512268567.675999, type 4 (EV_MSC), code 4 (MSC_SCAN), value 70014
Event: time 1512268567.675999, type 1 (EV_KEY), code 16 (KEY_Q), value 0
Event: time 1512268567.675999, -------------- SYN_REPORT ------------
Event: time 1512268568.531055, type 4 (EV_MSC), code 4 (MSC_SCAN), value 7001a
Event: time 1512268568.531055, type 1 (EV_KEY), code 17 (KEY_W), value 1
Event: time 1512268568.531055, -------------- SYN_REPORT ------------

...我已经将它们设置为0在KeyMapping字符串中将它们设置为以禁用它们，但在重新启动 X 后我发现它们并没有被禁用。如果我将指令更改Ignore为on而不是off，我发现我的整个 MagicKeyboard 都被禁用了（而我连接的其他键盘仍然有效）。

ButtonMapping 是一个指针函数（用于鼠标），但您已设置 MatchIsKeyboard，这意味着您正在尝试将其应用于键盘。键盘没有按钮。您可以使用以下命令检查：

xinput list

进而

xinput get-button-map <id-of-your-device>

无论如何，您可能不想为此使用 evdev 函数，听起来您想更改键盘映射。
