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