To rotate the screen, please follow theinstructions for the Raspberry Pi.
After rotating the screen, you will need to recalibrate the touchscreen or, in X Windows, you can add a transformation matrix like the following:
# 90-degree clockwise rotation xinput set-prop "Microchip Technology Inc. AR1100 HID-MOUSE" "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1 # 90-degree counterclockwise rotation xinput set-prop "Microchip Technology Inc. AR1100 HID-MOUSE" "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1 # 180-degree rotation xinput set-prop "Microchip Technology Inc. AR1100 HID-MOUSE" "Coordinate Transformation Matrix" -1 0 1 0 -1 1 0 0 1
To apply the setting each time the panel PC boots into X Windows, create a file in the /etc/X11/xorg.conf.d/ like /etc/X11/xorg.conf.d/01-touchscreen-rotation.conf with contents similar to the following:
Section "InputClass" Identifier "AR1100 Transformation Matrix" MatchProduct "Microchip Technology Inc. AR1100 HID-MOUSE" Option "TransformationMatrix" "-1 0 1 0 -1 1 0 0 1" EndSection
