@israel-neves Check the tvservice command

i build a 3.5 tft with recalbox, the thing is, the tvservice -s with HDMI plugged and not, gives the same answer

[Israel Neves]

Here the script that i want to run with S99custom

#!/bin/bash


IFS='  ' read -r -a array <<< "$(tvservice -s)"   # THIS LINE ! tvservice -s give the same answer with or without HDMI plug
echo "${array[1]}"
if [ "${array[1]}" == "0x12000a" ]; then
	echo "Sem HDMI"
	if [ "$(cat /boot/tela.txt)" == "hdmi" ]; then
		echo "Sem HDMI e setado como HDMI, setando como LCD"
		mount -o remount, rw /boot
		mount -o remount, rw /
		cp /boot/configLcd.txt /boot/config.txt
		echo "lcd" > /boot/tela.txt
		sh ./recalbox/scripts/recalbox-save-overlay.sh
		reboot
	else
		echo "Sem HDMI, tela setada como LCD"
		start-stop-daemon -S -q -m -b -p /var/run/fbcp.pid --exec /usr/bin/fbcp -- -n
	fi
	else
		echo "HDMI Conectado"
		if [ "$(cat /boot/tela.txt)" == "lcd" ]; then
			echo "Sem HDMI e setado como HDMI, setando como LCD"
		mount -o remount, rw /boot
		mount -o remount, rw /
		cp /boot/configHdmi.txt /boot/config.txt
		echo "hdmi" > /boot/tela.txt
		sh ./recalbox/scripts/recalbox-save-overlay.sh
		reboot
		fi
fi
