触摸屏幕 TouchScreen 校准

[eexpress]

买了一个usb接口的触摸屏幕。看各种误导，搞半天tslib/ts_calibrate/xinput各种参数。nnnnd

接入设备后的变化。

/dev/input/ 目录，插入设备后，增加了 event13 mouse2
xinput -list 增加了
⎜ ↳ eGalax Inc. USB TouchController id=15 [slave pointer (2)]
lsusb 增加了
Bus 003 Device 008: ID 0eef:0001 D-WAV Scientific Co., Ltd eGalax TouchScreen

/proc/bus/input/devices 增加
I: Bus=0003 Vendor=0eef Product=0001 Version=0100
N: Name="eGalax Inc. USB TouchController"
P: Phys=usb-0000:00:14.0-2/input0
S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.0/input/input20
U: Uniq=
H: Handlers=mouse2 event13
B: PROP=0
B: EV=b
B: KEY=400 0 0 0 0 0
B: ABS=3

结果是安装 xinput-calibrator utouch（不确定需要）直接就可以了。

代码： 全选

● xinput_calibrator 
Calibrating EVDEV driver for "eGalax Inc. USB TouchController" id=15
	current calibration values (from XInput): min_x=0, max_x=2047 and min_y=0, max_y=2047

Doing dynamic recalibration:
	Setting new calibration data: -3, 2047, -1, 2039


--> Making the calibration permanent <--
  copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf'
Section "InputClass"
	Identifier	"calibration"
	MatchProduct	"eGalax Inc. USB TouchController"
	Option	"Calibration"	"-3 2047 -1 2039"
EndSection

虽然xinput可以按照行修改参数

电阻屏？
系统识别为鼠标还是触摸屏？支持不支持滑动手势？
貌似现在的桌面环境对触屏优化不好。那举例，win8里能支持手势吗？

当然是电阻。电容的，可都是定制尺寸，不能随便就买到的。
看上面信息吧，mouse2和event13嘛。

你用的ubuntu的版本是多少的？ 10.04吗？？

各位大大，
我刚学用ubuntu,现用12.4的系统，接USB接口的电阻触摸屏，系统安装后，可以正常识别，但每次较正后，重新启动系统后又得重新校准。

代码:
● xinput_calibrator
Calibrating EVDEV driver for "eGalax Inc. USB TouchController" id=15
current calibration values (from XInput): min_x=0, max_x=2047 and min_y=0, max_y=2047

Doing dynamic recalibration:
Setting new calibration data: -3, 2047, -1, 2039


--> Making the calibration permanent <--
copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf'
Section "InputClass"
Identifier "calibration"
MatchProduct "eGalax Inc. USB TouchController"
Option "Calibration" "-3 2047 -1 2039"
EndSection
以上是得到的较正结果，根据提示和路径，我新建立了99-calibraton.conf，并将配置信息复制去，保存，重启系统，依然无效。 另将，配置信息保存到usr/share/x11/xorg.conf.d/10.evdev.conf之中，结果还是一样。


特些，来请教各位有使用过触摸屏的朋友,我接下来应该如何下手？谢谢
