我最近买了一台罗技M500：

Bus 002 Device 004: ID 046d:c069 Logitech, Inc. M500 Laser Mouse

它有九个按钮,我可以识别：

>左侧两个
>左,右
>轮压机
>滚轮向上滚动,滚轮向下滚动
>轮压左,轮按右

最后两个让我疯了.每次我尝试点击滚轮时,我都会意外地点击“左转滚轮”按钮,Firefox会转到最后访问过的页面.这很烦人.

够容易吧？只需找出xev显示哪些按钮并禁用它们.错误！ xev不会生成“ButtonPress / ButtonRelease”事件,但很奇怪
“LeaveNotify / EnterNotify / KeymapNotify”对：

 LeaveNotify event, serial 40, synthetic NO, window 0x4a00001,
    root 0x94, subw 0x0, time 2344319, (104,86), root:(113,207),
    mode NotifyGrab, detail NotifyAncestor, same_screen YES,
    focus YES, state 0

EnterNotify event, serial 40, synthetic NO, window 0x4a00001,
    root 0x94, subw 0x0, time 2344319, (104,86), root:(113,207),
    mode NotifyUngrab, detail NotifyAncestor, same_screen YES,
    focus YES, state 0

KeymapNotify event, serial 40, synthetic NO, window 0x0,
    keys:  4294967188 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

现在肯定的是,4294967188(如果有帮助的话,二进制补码中的-108为32位整数)将是键码,对吧？又错了！水平滚轮左/右和侧后/前按钮的数字相同.

这是我的设备的xinput列表：

它似乎按照正常情况映射按钮.那么当我在循环中编写一个调用“xinput query-state $DEVNO”的小脚本并按下可怕的按钮时会发生什么？你猜到了：

2 classes :
ButtonClass
    button[1]=up
    button[2]=up
    button[3]=up
    button[4]=up
    button[5]=up
    button[6]=up
    button[7]=up
    button[8]=up
    button[9]=up
    button[10]=up
    button[11]=up
    button[12]=up
    button[13]=up
    button[14]=up
    button[15]=up
    button[16]=up
ValuatorClass Mode=Relative Proximity=In
    valuator[0]=538
    valuator[1]=456
    valuator[2]=-2
    valuator[3]=-464

他们总是表现为“向上”,尽管他们显然是“向下”.确实生成正确的ButtonPress事件的鼠标按钮(例如左/右)确实会像他们应该的那样显示广告“向下”.

解决方法:

我有一台罗技M325,它还使用按钮8和9进行滚轮的左右倾斜.我用这个脚本来禁用它们：

#!/bin/bash

set -eu

MOUSE_ID=$(xinput --list | grep Logitech | sed -r 's/.*id=([0-9]+).*/\1/')

if [ -n "$MOUSE_ID" ]; then
    xinput set-button-map $MOUSE_ID 1 2 3 4 5 6 7 0 0
