conditionnal auto-launch on boot error

[Lowlow]

Hi!

In this forum’s Ideas for “Further Enhancements” section i proposed on RPI’s boot a way to launch emulationstation only if some controller is plugged with a .sh file containing :

#!/bin/bash

if [ "users | wc -w" -eq 1 ]; then
        if [ -e /dev/input/js0 ]; then
                exec "emulationstation"                   # Launch Gaming platform if a controller is plugged
        fi
fi

launched with this cron job:
@ reboot sleep 15 && sh /path/to/AutoLaunch.sh

I thought this was working..ES launch w/out any error outputs, but when trying to launch a rom screen flip to console then back at ES main screen.

Afterward i get this message:

Subject: Cron <lowlow@RPiStation> sleep 15 && sh /home/lowlow/AutoLaunch.sh

TERM environment variable not set.
tput: No value for $TERM and no -T specified

    tty_fd = open("/dev/tty", "w")
IOError: [Errno 6] No such device or address: '/dev/tty'

Any idea on what i’ve done wrong ? ’til now i tried many ways to got it working but no luck so far..

Btw, when launched manually it works well..this problem occur only with the auto-launch attempt.

it expects a terminal to be attached – instead of launching from cron, why not adjust the existing ES launch script to check for this (/usr/bin/emulationstation) or /etc/profile.d/10-emulationstation.sh which is triggered on boot.

Ahhhh damn good !

this is working smoothly now. There wasn’t any 10-emulationstation.sh because i hadn’t activated auto boot option during ES installation but anyway, just removed my cron job, and moved my actual .sh script there.

Thanks !!
