Question

我已经将带有HDMI和USB的Iiyama T1731SR-W1 17“触摸屏连接到我完全更新的Raspberry Pi。触摸不是即插即用，花了好几个小时才能让它正常工作。

dmesg 会出错，但我不确定它是否与

所以我认为设备已被正确识别，但是当我触摸屏幕时光标没有移动。我一直在尝试使用 xinput_calibrator 校准屏幕，但此工具也无法识别触摸事件。

我正在使用内核4.9.59-v7 +

请帮忙

我有完全一样的问题。我终于在一个荷兰论坛的帮助下修复了它： https://zeilersforum.nl/index.php/forum-125/73-stroom-elektrische-apparatuur-aan-boord/574771-faytech-touch-op-raspberry-pi-werkt-niet?start=25#841523

它归结为：

首先安装evdev：

sudo apt-get install xserver-xorg-input-evdev

在配置文件中更改驱动程序：

sudo nano /usr/share/X11/xorg.conf.d/40-libinput.conf

at the lines with touchscreen driver replace libinput by evdev

重新启动
