我已安装了来自waveshare的HDMI触摸屏 - https://www.waveshare.com/7inch-HDMI-LCD-C.htm
触摸事件在Raspian Stretch上运行良好，但在Kivy应用程序中不起作用。
这是输出：

我尝试将输入提供程序添加到~/.kivy/config.ini中，如下所示：
[input]
mouse = mouse
mtdev_%(name)s = probesysfs,provider=mtdev
hid_%(name)s = probesysfs,provider=hidinput
不确定[input]部分应该是什么。
答案 0 :(得分：0)
我正在使用这个确切的显示屏和触摸屏。尽管我在rpi4上使用了buster。 我发现如果kivy应用程序在没有装饰的情况下全屏运行，那么只要[input]下的ONLY项为
[input]
mtdev_%(name)s = probesysfs,provider=mtdev
基本上，您将不会使用Xwindows输入或HID输入。 还要确保[kivy]部分下的keyboard_mode = systemanddock。
