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"
