5. 在 XFree86 4 之下进行设定

(from Lee Monamy) ELO touch screen 的XF86Config-4设定:

---

Section "InputDevice"
        Identifier "ELO touchscreen"
        Driver "elographics"
        Option  "Device"        "/dev/ttyS0"
        Option  "MinimumXPosition"      "300"
        Option  "MaximumXPosition"      "3700"
        Option  "MinimumYPosition"      "300"
        Option  "MaximumYPosition"      "3700"
        Option  "UntouchDelay"  "10"
        Option  "ReportDelay"   "10"
        Option  "SendCoreEvents"        "yes"
EndSection

---

值得注意的是这个设定和 version 3 设定Device的不同, *not* a Port, otherwise you get an error.同样 version3 的 AlwaysCore 被 SendCoreEvents 取代.

你也要加入到ServerLayout,不用管X的信息: "(II) XINPUT: Adding extended input device "TOUCHSCREEN" (type: Elographics Touch Screen)"

---

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen  "Default Screen"
        InputDevice "Generic Keyboard"
...
        InputDevice "ELO touchscreen"
EndSection

5.1 其它的例子

from Dirk Mueller (for Microtouch SMT3 Series):

---

Section "InputDevice"
        Identifier  "MicroTouchFinger"
        Driver      "mutouch"
        Option      "Type" "finger"
        Option      "Device" "/dev/ttyS0"
        Option      "ScreenNo" "0"
        Option      "MinimumXPosition" "0"
        Option      "MaximumXPosition" "16383"
        Option      "MinimumYPosition" "0"
        Option      "MaximumYPosition" "16383"
EndSection

---

Option "Type" 可以是 "finger" 或 "stylus" Since Microtouch was bought by 3M-Touch, 参照 http://www.3M.com/3MTouchSystems/downloads/legacy.jhtml#Linux

5.2 附录

依据 Wong Yeow Sen, 设定的 option 名字在 XFree86 4.2 (at least with Red Hat 7.3)有所改变. 如果你的校准有误差请试试这个:

---

...
        Option  "MinX"      "100"
        Option  "MaxX"      "4000"
        Option  "MinY"      "100"
        Option  "MaxY"      "4000"
...
