Kiosk mode - swap the X and Y axes of the Mouse

If you are using touch screen in portrait mode, the touch input may have to be aligned to the new directions. One way to do is

• Install xinput - sudo apt-get install -y xinput

• export DISPLAY=:0.0 (sets the HDMI monitor as the display)

• xinput --list (output will be something as follows)

Virtual core pointer                    id=2 [master pointer  (3)]

⎜   ↳ Virtual core XTEST pointer              id=4 [slave  pointer  (2)]

⎜   ↳ Logitech USB Receiver                   id=7 [slave  pointer  (2)]

⎣ Virtual core keyboard                   id=3 [master keyboard (2)]

    ↳ Virtual core XTEST keyboard             id=5 [slave  keyboard (3)]

    ↳ Logitech USB Receiver                   id=6 [slave  keyboard (3)]

    ↳ Logitech USB Receiver                   id=8 [slave  keyboard (3)]

• Look for Touch device id - here it is 7 (logitech USB receiver) and use the ID in the below command (7 is used below)

• xinput --set-prop 7 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1
