Rotation

Note: To rotate the touch, you can re-compile the kernel as well. There is an example for reference (use 7inch HDMI LCD (C).)

Display Rotating

To rotating the display, you can append this statement to the config file

display_rotate=1 #1: 90; 2: 180; 3: 270

Reboot the Raspberry Pi

sudo reboot

Touch rotating

With the operation above. The screen could rotate in display. However, the touch works improperly. To rotate the touch as display, you could do as below:

1. install libinput

sudo apt-get install xserver-xorg-input-libinput

2. create an xorg.conf.d folder

sudo mkdir /etc/X11/xorg.conf.d

3. copy file 40-libinput-conf to the folder which we created

sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

4. Append a statement to touchscreen part of the file as below:

sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

5. save and reboot your Pi

sudo reboot

After completing these steps. The LCD could rotate 90 degree both display and touch.

Note:

90 degree: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

180 degree: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"

270 degree: Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"
