如何将校准参数应用于Elo系列TouchScreen？
如何将校准参数应用于Elo系列TouchScreen？
提问于 2019-12-18 10:00:05
在Xubuntu18.04中，我试图将校准参数应用到触摸屏上，但没有成功。这是我到目前为止..。
我可以手动连接设备并执行如下校准：
$ sudo /usr/bin/inputattach --daemon --always -elo /dev/ttyS2
$ xinput set-int-prop "Elo Serial TouchScreen" "Evdev Axis Calibration" 32 0 4095 0 4095
$ xinput_calibrator --output-type xinput
$ xinput set-int-prop "Elo Serial TouchScreen" "Evdev Axis Calibration" 32 -97 4087 -48 4108但是我设置的新参数没有效果，即使xinput列出了更新后的值。我发现的所有信息都相当陈旧。一些人建议应该使用evdev而不是libinput (稍后会详细介绍)，但是不能安装它。
下面是我在图形服务器配置中自动附加输入和处理校准时所做的工作：
$ cat /etc/udev/rules.d/99-elographics.rules
ACTION=="add|change", SUBSYSTEM=="tty|pnp", KERNEL=="ttyS2", TAG+="systemd", ENV{SYSTEMD_WANTS}+="elo-inputattach@%k.service"
$ cat /etc/systemd/system/elo-inputattach@.service
[Unit]
Description=inputattach for elo serial devices
[Service]
Type=simple
ExecStart=/usr/bin/inputattach -elo /dev/%I
$ cat /usr/share/X11/xorg.conf.d/99-calibration.conf
Section "InputClass"
Identifier "calibration"
MatchProduct "Elo Serial TouchScreen"
Option "MinX" "-1587"
Option "MaxX" "66954"
Option "MinY" "-690"
Option "MaxY" "67633"
Option "SwapXY" "0" # unless it was already set to 1
Option "InvertX" "0" # unless it was already set
Option "InvertY" "0" # unless it was already set
EndSection在99年的校准中，我尝试了各种选择，比如
Option "Calibration" "-97 4087 -48 4108"我还试图在该部分中将驱动程序设置为evdev，但它将恢复为libinput。

我从供应商那里收到了一个安装包，它不起作用，但帮助我找到了解决方案。
首先，要安装evdev，请执行以下操作：# apt install xserver-xorg-input-evdev-hwe-18.04。第二，使用驱动程序需要额外的X配置。最后，标定参数语法不正确。改进和补充情况列示如下：
$ cat /etc/udev/rules.d/99-elographics.rules
ACTION=="add|change", SUBSYSTEM=="tty|pnp", KERNEL=="ttyS2", TAG+="systemd", ENV{SYSTEMD_WANTS}+="elo-inputattach@%k.service"
$ cat /etc/systemd/system/elo-inputattach@.service
[Unit]
Description=Serial touch display enablement
Before=display-manager.service
[Service]
Type=simple
Restart=always
RestartSec=3s
ExecStart=/usr/bin/inputattach -elo /dev/%i
[Install]
WantedBy=graphical.target
$ cat /usr/share/X11/xorg.conf.d/50-touch-screen.conf
Section "InputClass"

MatchIsTouchscreen "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
EndSection
$ cat /usr/share/X11/xorg.conf.d/99-calibration.conf
Section "InputClass"
Identifier "calibration"
MatchProduct "Elo Serial TouchScreen"
Option "Calibration" "10 4080 80 4100"
Option "SwapAxes" "0"
