I’m trying to use the raspberry pi 3 in kisok mode on a 27" hdmi/touchscreen display on portrait mode
I’ve managed to rotate the display with the configuration
BALENA_HOST_CONFIG_display_hdmi_rotate=1 (equivalant to putting
but I struggle to rotate the touchscreen inputs.
should it be possible with configuration in
/boot/config.txt? I tried various
display_rotate=...but it changes nothing
should I be able to do that with udev rules ? if so how do I figure how to write the rule (selector and transformation matrice) ? and, can I try to apply a rule from the command line without restarting the device ?
