Setup: Boot to Browser (OctoPi or Jessie Light)

This is a guide for Jessie Light or OctoPi (0.13 and higher)

Follow this guide for Jessie Full.

If you're using OctoPi and the LCD-show drivers make sure you installed LCD-show-151102.tar.gz driver.

1. Make sure you've expanded your file system

2. Make sure all packages are up-to-date:

   sudo apt-get update
   

3. Install Chromium

4. Install all required modules:

   sudo apt-get install --no-install-recommends xinit xserver-xorg xserver-xorg-video-fbdev matchbox x11-xserver-utils unclutter
   

5. Register your touchscreen to X11 by creating a new config:

   sudo nano /usr/share/X11/xorg.conf.d/99-fbdev.conf
   

   • If your touchscreen is connected with HDMI, paste the following code:
     Use this if you're using the Official Pi Touchscreen

     Section "Device"
       Identifier "touchscreen"
       Driver "fbdev"
       Option "fbdev" "/dev/fb0"
     EndSection
     

   • If your touchscreen is connected with SPI, paste the following code:

     Section "Device"
       Identifier "touchscreen"
       Driver "fbdev"
       Option "fbdev" "/dev/fb1"
     EndSection
     

   Save and exit (CTR-O, enter and CTR-X)

6. Allow X11 to run as anybody by running the following command:

   sudo sed -i 's/allowed_users=console/allowed_users=anybody/' /etc/X11/Xwrapper.config
   

7. Get the TouchUI boot files:

   wget -P /home/pi/ https://github.com/BillyBlaze/OctoPrint-TouchUI/archive/autostart.zip
   unzip -d /home/pi/ /home/pi/autostart.zip
   

8. Copy service file and register it as auto boot:

   sudo cp ~/OctoPrint-TouchUI-autostart/touchui.init /etc/init.d/touchui
   sudo chmod +x /etc/init.d/touchui
   sudo cp ~/OctoPrint-TouchUI-autostart/touchui.default /etc/default/touchui
   sudo update-rc.d touchui defaults
   

9. Reboot

• You can also safely remove autostart.zip. Do not remove the directory ~/OctoPrint-TouchUI-autostart and if you change the path of this directory then edit the file /etc/default/touchui with the new path.

• Don't forget to turn on Touchscreen mode in the TouchUI Setting dialog to enhance performance.

• Troubleshooting:

  • Calibration
  • Inverted Axis
  • Webcam image not working
