I'm trying to install a launch-file to run at boot on my odroid (lubuntu). It use face detection (opencv) and audio for pocket-shinx for speech recognizer. Looking at the log file my launch file is executed but I get warning/errors. The launch file works when I run it manually. The errors are:

(MyVideo:3247): Gtk-WARNING **: cannot open display: [face_detector-4] process has died ...

...

[ERROR] [WallTime: ...] Error processing request: no element "PulseAudio"

Seems like the display is not set up here and PauleAudio is not found. Do I need to wait until they have started? Synchnize in some way or do I need to setup some additional environment variables? Permissions?
