在16:10屏幕上调整4:3宽宽比的触摸屏坐标
在16:10屏幕上调整4:3宽宽比的触摸屏坐标
提问于 2019-07-12 19:46:36
你好，我最近有个奇怪的设备。这是一款本机分辨率为800x1280的平板电脑-是的，它是向后的。显示器处于纵向模式，我必须做一些xorg配置编辑，以旋转屏幕和旋转触摸屏。如果我使用本机分辨率，这是很好的，但是我试图让它使用一个768x1024分辨率。我已经成功地在4:3模式下获得了768x1024分辨率(旁边有黑条，这正是我想要的)，使用以下命令在平板上显示：
user1:~ # xrandr --newmode "768x1024_60.00" 65.25 768 816 896 1024 1024 1027 1037 1063 -hsync +vsync
user1:~ # xrandr --addmode DSI-1 768x1024_60.00
user1:~ # xrandr -s 768x1024_60.00我遇到的问题是如何让实际的触摸屏数字化器与它保持一致，就好像它还停留在16:10。下面是我的xorg配置文件：
user1:~ # cat /etc/X11/xorg.conf.d/99-touchscreen.conf
Section "InputClass"
Identifier "evdev touchscreen catchall"
MatchIsTouchscreen "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "SwapAxes" "true"
Option "InvertY" "true"
EndSection
user1:~ # cat /etc/X11/xorg.conf.d/50-monitor.conf
Section "Monitor"
Identifier "DSI-1"
Option "Rotate" "right"
EndSection以下是触摸屏的属性：

我能够用xinput_calibrator解决这个问题，这给了我正确的xorg校准数据。
基本上，打开一个终端窗口并启动xinput_calibrator并触摸它要求您触摸的点。完成后，终端窗口将显示与xorg一起使用的信息：
user1:~> xinput_calibrator
Calibrating EVDEV driver for "Goodix Capacitive TouchScreen" id=11
current calibration values (from XInput): min_x=66, max_x=725 and min_y=-5, max_y=1284
Doing dynamic recalibration:
Setting new calibration data: 61, 730, -3, 1272
--> Making the calibration permanent <--
copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf'
Section "InputClass"
Identifier "calibration"
MatchProduct "Goodix Capacitive TouchScreen"
Option "Calibration" "61 730 -3 1272"
