These configurations will also effect the HDMI display, so if you want to use HDMI display, you need to remove them.

You need to create Xorg configuration file and autostart script for setting the resolution.

1. Create Xorg configuration file /etc/X11/xorg.conf.d/10-ts050-fbdev-rotate.conf.

Section "Device"
    Identifier "Configured Video Device"
    # Rotate off
#   Option "Rotate" "off"
    # Rotate Right / clockwise, 90 degrees
    Option "Rotate" "CW"
    # Rotate upside down, 180 degrees
#   Option "Rotate" "UD"
    # Rotate counter clockwise, 270 degrees
#   Option "Rotate" "CCW"
 
EndSection
 
Section "InputClass"
    Identifier "Coordinate Transformation Matrix"
    MatchIsTouchscreen "on"
    MatchProduct "EP0000M09"
    MatchDriver "libinput"
    # Rotate Right / clockwise, 90 degrees 
    Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
    # Rotate upside down, 180 degrees
#   Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
    # otate counter clockwise, 270 degrees 
#   Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"
EndSection

2. Create Resolution setting autostart file /etc/xdg/autostart/panel-setup.desktop.

[Desktop Entry]
Version=1.0
Name=pixel
Exec=xrandr --output "default" --mode "1920x1088"
Terminal=false
Type=Application
Categories=

Server OS

You can rotate the framebuffer console in two ways.

  • System Node
  • Configuration File

Framebuffer console rotation value:

  • 0 - default value (landscape mode)
  • 1 - rotate 90 degrees
  • 2 - rotate 180 degrees
  • 3 - rotate 270 degrees

1. Rotate via system node.

  • Check the current configuration of the node.
    khadas@Khadas:~$ cat /sys/class/graphics/fbcon/rotate
    0
  • Modify the configuration to rotate the framebuffer(90 degrees).
    khadas@Khadas:~ $ echo 1 | sudo tee /sys/class/graphics/fbcon/rotate
    khadas@Khadas:~ $ cat /sys/class/graphics/fbcon/rotate
    1
  • Restore framebuffer console to the default setting.
    khadas@Khadas:~ $ echo 0 | sudo tee /sys/class/graphics/fbcon/rotate
    khadas@Khadas:~ $ cat /sys/class/graphics/fbcon/rotate     
    0

The modification will be lost after a power cycle, if you want to save it you can check the other way below.

2. Rotate via configuration file

  • Check related configuration.
    khadas@Khadas:~$ cat /boot/env.txt | grep "fb_rotate"
    fb_rotate=0
  • Change setting(rotate 90 degrees):
    khadas@Khadas:~$ sudo vim /boot/env.txt
    fb_rotate=0 change to fb_rotate=1

You need to save the file and reboot the board.
