一、参考文档：
    tslib移植的问题：No raw modules loaded.ts_config:No such file or directory
        http://blog.csdn.net/imxiangzi/article/details/7472883
二、cat /etc/profile
    ......
    # set tslib
    export TSLIB_ROOT=/usr/local/arm/tslib
    export TSLIB_TSDEVICE=/dev/input/event1
    export TSLIB_CALIBFILE=/etc/pointercal
    export TSLIB_CONFFILE=$TSLIB_ROOT/etc/ts.conf
    export TSLIB_PLUGINDIR=$TSLIB_ROOT/lib/ts
    export TSLIB_FBDEVICE=/dev/fb0
    export PATH=$TSLIB_ROOT:$PATH
    ......

三、cat /ts_confg
    # Uncomment if you wish to use the linux input layer event interface
    # module_raw input
    
    # Uncomment if you‘re using a Sharp Zaurus SL-5500/SL-5000d
    # module_raw collie
    
    # Uncomment if you‘re using a Sharp Zaurus SL-C700/C750/C760/C860
    # module_raw corgi
    
    # Uncomment if you‘re using a device with a UCB1200/1300/1400 TS interface
    # module_raw ucb1x00
    
    # Uncomment if you‘re using an HP iPaq h3600 or similar
    # module_raw h3600
    
    # Uncomment if you‘re using a Hitachi Webpad
    # module_raw mk712
    
    # Uncomment if you‘re using an IBM Arctic II
    # module_raw arctic2

    module pthres pmin=1
    module variance delta=30
    module dejitter delta=100
    module linear

四、错误现象：
    zengjf login: root
    login[1410]: root login on ‘ttymxc0‘
    No raw modules loaded.
    ts_config: No such file or directory
    [zengjf@root ~]# 

五、解决方法：
    把tslib/etc目录下的ts.conf的"#module_raw input"的注释符号"#"去掉，前面别留空格。

六、正常现象：
    zengjf login: root
    login[1410]: root login on ‘ttymxc0‘
    xres = 640, yres = 480
