Is there a way to flip the display 180 deg using the smos shell commands?
Yes, is very simple using just one command:
echo 2 | sudo tee /sys/class/graphics/fbcon/rotate
This will rotate 180 deg the text console. Console preview in dashboard will be still normal
echo 0 | sudo tee /sys/class/graphics/fbcon/rotate
This will revert back to normal (0 deg rotation)
Please notice that will work only to first reboot.
You can add this to startup script /root/utils/rclocal, but with nearest rig update with this file your changes will be overwritten with default.
Small hint is add custom cron script in /etc/cron.d/yourfile that will not be everwrite by our rig updates.
