无法从/ dev / input / event *获取鼠标移动事件 [英] can't get the mouse move event from /dev/input/event*
问题描述
当使用 evtest >时,我无法获取鼠标移动事件a>测试输入事件的工具。
I can't get the mouse move event when using the evtest tools to test the input events .
我只需要三个鼠标事件:
I just get three mouse events:
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
无鼠标移动事件。所以我的鼠标移动事件和如何捕获它?
No mouse move event. So where my mouse move event and how to capture it?
ps:测试在$ code Ubuntu 11.04 和 Gentoo
在VirtualBox-4中安装了virtualBox-addition。
ps: Tested on Ubuntu 11.04
and Gentoo
in VirtualBox-4 with virtualBox-addition installed.
推荐答案
如果没有嵌入式linux系统,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
)
If not on an embedded linux system I prefer to use the input-utils tools rather than evtest (and if I'm on Android I use cat /proc/bus/input/devices
and getevent
)
通过以下方式安装input-utils:
Install input-utils via:
$ sudo apt-get install input-utils
列出我所有的输入设备
$ 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
然后我在笔记本电脑的追踪点上看到事件(不要忘了在开始输入事件之后移动它)
Then I read events on my laptop's trackpoint (don't forget to move the it around after starting input-events)
$ sudo input-events 12
/dev/input/event12
bustype : BUS_I8042
vendor : 0x2
