Couldn‘t open tslib config file : No such file or directory

使用sudo执行tslib报错

song@imx6ul:/opt/tslib/bin$ sudo ./ts_test
[sudo] password for song: 
Couldn't open tslib config file : No such file or directory
ts_config: No such file or directory
ts_open: No such file or directory

切换到root执行问题解决

song@imx6ul:/opt/tslib/bin$ su
Password: 
root@imx6ul:/opt/tslib/bin# ./ts_test

执行./ts_test后触摸按键发现lcd上的描点与触点成镜像，获取到的原定坐标在lcd屏的右下角
解决办法：
打开 /opt/tslib/etc/ts.conf
屏蔽 module linear
