Set up your Raspberry Pi

Configure device

• Raspberry Pi rotate display 90 degree
  • Append display_rotate=1 to /boot/config.txt (0=no-rotation, 1=90, 2=180, 3=270, 0x10000=h-flip, 0x20000=v-flip)
  • Append gpu_mem=128 to /boot/config.txt
  • OpenGL Driver를 사용하는 경우, vc4-kms-v3d driver가 dispay의 rotate를 지원하지 않는다고 한다. 아래와 같이 수정해준다.

tee -a ~/.config/lxsession/LXDE-pi/autostart << __EOF__
@xrandr --output HDMI-1 --rotate right
__EOF__
