Rotation
Method 1: Graphical Interface Rotation
In the start menu, select: Preferences -> Screen Configuration -> Configure -> Screens -> DSI-1 -> Orientation, select the corresponding angle in it, click "√", select Yes, and restart.
Method 2: Rotation Display In Lite Version
sudo nano /boot/cmdline.txt #Add a command corresponding to the display rotation angle at the beginning of the cmdline.txt file, save it and restart it to take effect #display rotated 90 degrees video=DSI-1:400x1280M@60,rotate=90 #display rotated 180 degrees video=DSI-1:400x1280M@60,rotate=180 #display rotated 270 degrees video=DSI-1:400x1280M@60,rotate=270
Touch To Rotate
sudo nano /boot/config.txt #Modify the instruction of the touch rotation angle at the end of the config.txt file, and it will take effect after restarting (there is a 0° touch direction instruction by default) #90°： dtoverlay=WS_xinchDSI_Touch,invertedy,swappedxy #180°： dtoverlay=WS_xinchDSI_Touch #270°： dtoverlay=WS_xinchDSI_Touch,invertedx,swappedxy #0°： dtoverlay=WS_xinchDSI_Touch,invertedx,invertedy
Disable Touch
At the end of the config.txt file, add the following commands corresponding to disabling touch (the config file is located in the root directory of the TF card, and can also be accessed through the command: sudo nano /boot/config.txt):
disable_touchscreen=1
Note: After adding the command, it needs to be restarted to take effect.
Precaution
1. Update the system, such as executing the following command:
sudo apt-get update sudo apt-get full-upgrade
After updating the system, some files of the originally installed driver may be overwritten, and the driver needs to be reinstalled to display normally.
2. Replace the motherboard
If the driver is originally installed on the Raspberry Pi 4 Model B, the user replaces the motherboard, such as modifying it to a Raspberry Pi 3 Model B+, the display will not display properly.
Because Pi4 and Pi3 need to load different driver files, you need to reinstall the driver on the new motherboard to display properly.
