Elo触摸屏型号：
- Elo TouchSystems, Inc. Elo TouchSystems 2700 IntelliTouch(r)
问题描述：
- 我的问题 + 其他人的问题是，当我触摸（鼠标悬停）触摸屏时，鼠标光标不跟随我的（手指/触摸）移动。按下时，光标按（单击）在错误的位置。
我的目标是修复它，以便按压位置准确。
尝试过
我已进行以下尝试，但没有成功。
1）查询/设备状态
--
udi = '/org/freedesktop/Hal/devices/usb_device_4e7_20_20B23159_if0_logicaldev_input'
button.has_state = false (bool)
info.addons.singleton = {'hald-addon-input'} (string list)
info.capabilities = {'input', 'button', 'input.mouse'} (string list)
info.category = 'input' (string)
info.parent = '/org/freedesktop/Hal/devices/usb_device_4e7_20_20B23159_if0' (string)
info.product = 'Elo TouchSystems, Inc. Elo TouchSystems 2700 IntelliTouch(r) USB Touchmonitor Interface' (string)
info.subsystem = 'input' (string)
info.udi = '/org/freedesktop/Hal/devices/usb_device_4e7_20_20B23159_if0_logicaldev_input' (string)
input.device = '/dev/input/event11' (string)
input.originating_device = '/org/freedesktop/Hal/devices/usb_device_4e7_20_20B23159_if0' (string)
input.product = 'Elo TouchSystems, Inc. Elo TouchSystems 2700 IntelliTouch(r) USB Touchmonitor Interface' (string)
input.x11_driver = 'evdev' (string)
linux.device_file = '/dev/input/event11' (string)
linux.hotplug_type = 2 (0x2) (int)
linux.subsystem = 'input' (string)
linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0/input/input11/event11' (string)
2）添加新文件
$ vim /etc/X11/xorg.conf.d/elo.conf
Section "InputDevice"
Identifier "touchscreen1"
Driver "elographics"
Option "Device" "/dev/ttyS0"
Option "MinX" "470"
Option "MaxX" "3670"
Option "MinY" "600"
Option "MaxY" "3550"
Option "ScreenNumber" "0"
Option "ReportingMode" "Scaled"
Option "ButtonThreshold" "17"
Option "ButtonNumber" "1"
Option "SendCoreEvents"
EndSection
3）注销并重新启动X
4）结果仍然一样，没有任何改善。
我感谢您对此的建议。

现在，我的右屏幕分辨率为 1024x768，左笔记本电脑屏幕分辨率也为 1024x768，使用上述语句，鼠标光标可以很好地适应。如果我的分辨率不同，当然需要对其进行微调。

我有一些装有 Fedora 25 的 PC 和一个 Elo 显示器，它们都在运行，我只需运行 Elo 触摸校准工具来校准精度即可
