旋转的debian触摸屏上的触摸屏校准错误

Question

Debian映像安装在HDD上。当debian映像启动并且屏幕位置水平时，触摸屏正常工作，校准正在工作。但是当屏幕旋转90度时，触摸屏校准无法正常工作。它需要校准。我试过xinput_calibrator但它没有工作。

如何解决触摸屏旋转时的校准问题？

Answer 1

当您使用xinput_calibrator时，它会在/etc/X11/xorg.conf.d/99-calibration.conf（例如：1399 15891 421 15482）上创建一组校准值。这些值以“常规”水平方式正确显示屏幕。

当您旋转屏幕时，值和轴的交换不是自动的，因此它不能正常工作。这有点复杂，但您可以通过制作bash脚本来更正轴交换和校准值来解决此问题。

我创建了一个我们公司使用的程序 - 它可以免费使用。以下是该程序，请注意，您必须稍微玩一下，然后找到适合您的东西（您可能不需要取消注释所有行，它因屏幕而异）。在下面的情况下，我使用Fujitsu Component USB Touch Panel作为屏幕的名称，您应该使用xinput来标识您的屏幕名称并替换该名称。此外，旋转后重新启动“面板”非常重要，在我们的情况下，我们使用LXDE，因此我用lxpanelctl restart重新启动，在您的情况下可能会有所不同。

试着去理解剧本的逻辑并使其适用于您的需求：

## rotatezz version 1.0.0 
## This file is part of the rotatezz program. This program will attempt 
## to rotate the screen orientation of your computer in a clockwise way. 

## Important notes: in case of a wacom being present, need to update the device name (or number, if many devices present with same name, 
## although risky because numbers can change), and comment/uncomment specific lines below, including the "xsetwacom set" line. 
## Also, when rotating, the touchscreen not always invert the touch map; in addition, the calibration (that works for normal) won't work well 
## because it will be inverted. Thus, uncomment lines below (changing the device name) to swap axis as it rotates, and also swap calibration 
##(1st value swaps with 3 value, and the second swaps with the 4th)

那么这个程序是keybinded与使得屏幕旋转（每次按下旋转按钮计时按钮，这程序应该启动）。我希望这有帮助！
