linux触摸板开关――by xzh
[root@XiaoZH input]# yum install xorg-x11-apps
---------------------------------------------
[root@XiaoZH input]# cd /dev/input
[root@XiaoZH input]# ls
by-id event1 event12 event3 event6 event9 mouse1
by-path event10 event13 event4 event7 mice mouse2
event0 event11 event2 event5 event8 mouse0
看到很多个设备
[root@XiaoZH input]# cat mouse0
[root@XiaoZH input]# cat mouse1
（一些看不懂的字符）
[root@XiaoZH input]# cat mouse2
有三个mouse 用cat mouse 当碰触触摸板时出现乱码就证明这个时触摸板 如我这个是mouse1
确定触摸板名字后
[root@XiaoZH input]# cd /proc/bus/input/
[root@XiaoZH input]# cat devices
