This method is only suitable for HDMI capacitive screen, not suitable for GPIO resistive screen
How to rotate display direction:
1. Open the “config.txt” file (the “config.txt” file is located in /boot):
sudo nano /boot/config.txt
2.Add the statement in the “config.txt” file, press Ctrl+X to exit, press Y to save.
display_rotate=1 #0: 0; 1: 90; 2: 180; 3: 270
3. Restart the Raspberry Pi after saving.
sudo reboot
How to rotate Touch direction:
After the display is rotated, the touch needs to be modified.
1. Install libinput
sudo apt-get install xserver-xorg-input-libinput
2. Create the xorg.conf. D directory in /etc/x11 / below (if the directory already exists, this will proceed directly to step 3)
sudo mkdir /etc/X11/xorg.conf.d
3. Copy the file “40-libinput.conf” to the directory you just created.
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
4. Edit “/etc/X11/xorg.conf.d/40-libinput.conf”
sudo nano /etc/X11/xorg.conf.d/40-libinput.conf
Find a part of the touchscreen , add the following statement inside, press Ctrl+X to exit, press Y to save.
Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
5. Restar your Raspberry Pi
sudo reboot
Complete the above steps for a 90 degree rotation.
Note:
0 degrees of rotation parameters: Option "CalibrationMatrix" "1 0 0 0 1 0 0 0 1"
90 degrees of rotation parameters: Option "CalibrationMatrix" "0 1 0 0 -1 1 0 0 1"
180 degrees of rotation parameters: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
270 degrees of rotation parameters: Option "CalibrationMatrix" "0-1 1 1 0 0 0 0 1"
