Changing the Screen Orientation

The Screen Orientation of the display can be changed. To implement this,

there are two things that need to be changed:

1. Rotate Screen Orientation

Run the command:

Find the "Device Section" with "Builtin Default fbdev Device 0"

identifier as below and add the text in red in the section.

Section "Device"

Identifier "Builtin Default fbdev Device 0"

Driver "fbdev"

Option "Rotate" "CCW"

EndSection

2. Rotate and set the touch coordinates

Run the command:

Find the "InputClass" section with "libinput touchscreen catchall" identifier as

below and add the text in red in the section.

Section "InputClass"

Identifier "libinput touchscreen catchall"

MatchIsTouchscreen "on"

MatchDevicePath "/dev/input/event*"

Driver "libinput"

Option "TransformationMatrix" "0 -1 1 1 0 0 0 0 1"

EndSection

Save the files and reboot. The screen should already be in portrait mode after

rebooting.

sudo nano /etc/X11/xorg.conf

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