Raspberry pi eGalax触摸屏&x2B；覆盆子皮

我已将Iiyama T1731SR-W1 17英寸带HDMI和USB的触摸屏连接到我的完全更新的Raspberry Pi。该触摸屏无法即插即用，并花费了数小时试图使其工作

dmesg给出了一个错误，但我不确定是否与此有关

因此，我认为设备已被正确识别，但当我触摸屏幕时光标未移动。我一直在尝试使用xinput_calibrator校准屏幕，但该工具也无法识别触摸事件

我正在使用内核4.9.59-v7+

---

请帮助我，我也有同样的问题。 在荷兰论坛的帮助下，我终于修复了它：

归结起来是：

• 首先安装evdev：

sudo apt get install xserver xorg input evdev

• 更改配置文件中的驱动程序：

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

• 重新启动

---

首先尝试

sudo rpi update；sudo apt get update；sudo apt get upgrade

然后重试…驱动程序的版本似乎有问题？！…或者最好按照制造商手册进行安装。我忘了告诉您我已经完成了：）。以下制造商的自动驱动程序安装不起作用Eitermine是

Linux4.9.70-v7+

然后你必须至少做

sudo rpi更新

然后重新启动并检查againIt说

你的固件已经是最新的

你是在rpi3上使用NOOBS还是Raspbian…还是其他什么…？NOOBS有很多问题…我已经改为Raspbian，很多事情都是在低级别上修复的l设备管理…如usb模块和UART同步等
