See Setup section in tfluna/README.md.

Autostart scripts

Run GUI script in lxterminal via XDG desktop entry:

mkdir -p ~/.config/autostart
touch ~/.config/autostart/museumlabel.desktop

add the following to ~/.config/autostart/museumlabel.desktop which runs thedisplay.sh script after the user logs into LXDE:

[Desktop Entry]
Type=Application
Version=1.0
Name=IntelligentTextLabel
Exec=/usr/bin/lxterminal -e /home/pi/museum-label/display.sh
Categories=Utilities

Using a wrapper script

Additional flags to display.sh can be added to the Exec line such as /display.sh --host. If the flags or configuration are relatively long, these can be put inside a wrapper script:

  1. Create a run script to call display.sh such as ~/rundisplay:
touch ~/Desktop/rundisplay
chmod +x ~/Desktop/rundisplay
  1. Add the following to ~/Desktop/rundisplay and call display.sh with the required flags:
#! /bin/sh
~/museum-label/display.sh --host localhost ...
  1. Edit ~/.config/autostart/museumlabel.desktop and set the Exec line to call the run script:
Exec=/usr/bin/lxterminal -e /home/pi/Desktop/rundisplay

Enable Screen Sharing

Enable the VNC server on the RPI for remote management:
