问题描述
我刚刚购买了带有 7 英寸显示屏和外壳的 Raspberry Pi 3.
I've just bought a Raspberry Pi 3 with a 7" Display touch screen and a casing.
不幸的是，外壳不能让我手动旋转屏幕，所以我的应用程序运行颠倒.
Unfortunately, the casing can't allow me to rotate manually the screen so my apps are running upside down.
我尝试使用以下 adb 命令从控制台执行此操作，但没有成功:
I've tried to do it from the console using the following adb commands but with no luck:
adb shell content insert --uri content://settings/system --bind name:s:accelerometer_rotation --bind value:i:0
然后
adb shell content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:1
或
adb shell content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:3
有什么办法可以直接从配置标志中做到从启动开始处理屏幕方向吗?
Is there any way to do it from a config flag directly that screen orientation is handled from boot ?
推荐答案
我终于找到了如何实现它.
I find out finally how to achieve it.

您必须从笔记本电脑上的 sdcard 挂载启动分区并编辑 /boot/config.txt 文件并添加以下行:
You have to mount the boot partition from the sdcard on your laptop and edit the /boot/config.txt file and add the following line:
lcd_rotate=2
与 display_rotate=2 相比，通过添加这条线，显示器和触摸屏都将旋转，只有显示器旋转，触摸屏保持颠倒.
By adding this line both display and touchscreen will be rotated, compared to display_rotate=2 where only display is rotated and touchscreen remains upside down.
