使用evtest工具测试输入事件时,我无法获得鼠标移动事件.

我刚刚得到三个鼠标事件：

left click event: type = EV_KEY, code = 272 (LeftBtn), value=1/0

right click event: type = EV_KEY, code = 273 (RightBtn), value = 1/0

mouse wheel event: type = EV_REL, code = 8 (Wheel), value = -1

没有鼠标移动事件.那么我的鼠标移动事件以及如何捕获它？

ps：在安装了virtualBox-addition的VirtualBox-4中测试Ubuntu 11.04和Gentoo.

解决方法:

如果不是在嵌入式Linux系统上,我更喜欢使用input-utils工具而不是evtest(如果我在Android上,我使用cat / proc / bus / input / devices和getevent)

通过以下方式安装input-utils：

$sudo apt-get install input-utils

列出我的所有输入设备

$sudo lsinput
/dev/input/event0
   bustype : BUS_HOST
   vendor  : 0x0
   product : 0x5
   version : 0
   name    : "Lid Switch"
..
..
   phys    : "isa0060/serio1/input0"
   bits ev : EV_SYN EV_KEY EV_ABS    
/dev/input/event12
   bustype : BUS_I8042
   vendor  : 0x2
   product : 0xa
   version : 0
   name    : "TPPS/2 IBM TrackPoint"
   phys    : "synaptics-pt/serio0/input0"
   bits ev : EV_SYN EV_KEY EV_REL

然后我在我的笔记本电脑的轨迹点上读取事件(不要忘记在启动输入事件后移动它)

$sudo input-events 12
/dev/input/event12
   bustype : BUS_I8042
   vendor  : 0x2
   product : 0xa
   version : 0
   name    : "TPPS/2 IBM TrackPoint"
   phys    : "synaptics-pt/serio0/input0"
   bits ev : EV_SYN EV_KEY EV_REL
