我有一个想要配置的蓝牙鼠标，我的 99-eleocmtrackball.conf 文件如下/etc/X11/xorg.conf.d所示：
Section "InputClass"
Identifier "evdev mouse"
Driver "evdev"
MatchProduct "ELECOM TrackBall"
MatchIsPointer "yes"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "8"
Option "AccelProfile" "flat"
Option "AccelSpeed" "-0.9"
Option "ButtonMapping" "3 2 3 4 5 0 0 8 9"
EndSection
虽然滚轮模拟可以很好地与按钮 8 配合使用，但未应用 ButtonMapping，并且鼠标输入采用默认设置。我的/var/log/Xorg.0.log文件如下所示：

Configuring as keyboard我该如何让 ButtonMapping 选项工作？行后的日志是否Configuring as mouse正常？如果您需要任何其他信息，请告诉我。谢谢！

我以前使用 xorg.conf 进行按钮映射。但如果我想更改映射，我必须重新启动。最近我转向绑定键并xte作为xautomation更通用的替代方案。要点是添加xbindkeys到您的~/.xprofile或~/.xinitrc文件并编辑~/.xbindkeysrc。
这是我的~/.xbindkeysrc：
# Fn2 to middle btn
"xte 'mouseclick 2'"
b:10+Release
# Fn3 to right btn
"xte 'mouseclick 3'"
b:12+Release
# Forward/Back
"xte 'key Page_Up'"
b:9+Release
"xte 'key Page_Down'"
b:8+Release
