Launching an GUI app with udev rule after plugging in usb?

so Im trying to run gui app with udev but with 0 success,

I read somewhere that i have to find Xauthority file, and put display variable in scripts, Is this right, and if yes could someone write an example script?

Thank you in advance :)

MY CURRENT SETUP :

SUBSYSTEMS=="usb", ATTRSidProduct=="1337", ACTION=="add", RUN+="/usr/local/bin/New.sh"

Script New.sh

#!/bin/sh
./New2.sh & exit

Script New2.sh

#!/bin/sh
vlc v4l2:///dev/video0

First problem is that current directory is undefined. So ./New2 sh won't look in the right place. You'll need to change that to an absolute path. I'd suggest you use logger to provide a trace of what's going on. You'll see the output in somewhere such as /var/log/user.log. Try logger 'This is a test' and then grep -l 'This is a test' /var/log/* to find out for sure.

Second problem is that there is no permission for vlc to write to your display, and it doesn't know what display to use. Take a look at similar questions here asking about running a GUI app from cron. It's the same set of issues you need to address.
