java - No X11 DISPLAY variable was set -


i running raspbian fadecandy server, using vncserver load x11 instance , running java app drive fadecandy controlled leds. need load during boot process.

in /etc/init.d/ have bash script called fadecandy:

#! /bin/sh # /etc/init.d/fadecandy # start fadecandy server  sudo fcserver & sudo vncserver & export display=":1" /home/pi/fadecandy/runstopturn/runstopturn &

runstopturn fails execute. if logon system , manually run error "no x11 display variable set..."

by typing following @ prompt:

export display=":1" runstopturn

then works fine.

i need setting display variable or passing java script on boot.

hard without more logs, why running vncserver root? start of problems.

try running less-privileged user (create 1 if necessary), or if have to, run entire script root - mixing , matching users make environments , config hard right.

edit: additionally, check /bin/sh points to. on small installs, less bash-like first think (i.e. might need use setenv - some details here).
