[Ubuntu-zh] 求助！触摸屏

[BX]

我买了一个小的5.6寸触摸屏（tft屏幕+电阻触摸面板）
然后在第一次连接的时候，可以正常使用。
xinput list返回结果中，有一个
eGalax Inc. USB TouchController         	id=8	[slave  pointer  (2)]
于是用xinput set-int-prop 8 （后面忘了具体的）对其进行校准
然后将校准命令写进了/etc/X11/Xsession.d
重启后触摸屏失效。（在win7下确认触屏未损坏）
此时用xinput list返回结果变成
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ eGalax Inc. USB TouchController         	id=8	[slave  pointer
(2)] ***************
⎜   ↳ eGalax Inc. USB TouchController         	id=9	[slave  pointer
(2)] ***************
⎜   ↳ Microsoft Comfort Curve Keyboard 2000   	id=11	[slave  pointer  (2)]
⎜   ↳ USB Optical Mouse                       	id=12	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ Microsoft Comfort Curve Keyboard 2000   	id=10	[slave  keyboard (3)]

也就是多了一个触摸屏……用xinput test 8或者9都没有反应
在hal-device中查询：hal-device | grep -i "touch" -5

邮件内容比较长，感谢拨冗阅读。对于这种情况有没有什么提示？
