RaspberryPi with Roon Bridge and display

Hardware

Raspberry Pi 3 Model B with DietPi including Roon Bridge and display for my Home Assistant installation.

Installation

DietPi

After initial bootup, login through ssh: ssh root@dietpi

Password: dietpi

After confirmation DietPi will update itself.

1. Select Software
2. Software Optimized -> Desktops -> 133 Chromium
3. Software Optimized -> Media Systems -> 121 Roon Bridge
4. Install the software

Configure Sound Card

dietpi-config

Audio -> Soundcard -> hifiberry-digi

Rotate the display

In my configuration I had to rotate the display 180 degrees:

DietPi-Config -> Display Options -> Rotation (LCD)

Console boot up

There’s a way to configure DietPi to boot into a Chromium window. But with the following procedure you will get the following advantages:

• No cursor
• No scroll bar
• Turn your screen off after a given time
  • DietPi has disabled dpms by default. So you’ll have to remove /etc/X11/xorg.conf.d/98-dietpi-disable_dpms.conf.

1. As root, run the autostart configuration:
2. dietpi-autostart
3. Select Custom - /var/lib/dietpi/dietpi-autostart/custom.sh
4. Save and exit

System configuration

1. Modify the custom.sh startup script
2. nano /var/lib/dietpi/dietpi-autostart/custom.sh
3. Add this to the bottom of the file:

   # Run the custom kiosk script
   xinit /root/kiosk.sh -- -nocursor
   

4. Save and exit
5. Make the custom.sh script executable
6. chmod +x /var/lib/dietpi/dietpi-autostart/custom.sh
7. Create the kiosk.sh script
8. nano /root/kiosk.sh
9. Paste the following code as content:

#!/bin/sh

#######################################
#
# Start up script for running the
# Chromium web browser full screen
#
#######################################

# Set the X display
export DISPLAY=":0"
# Tune the screen blanking time - time in seconds (standby, suspend, off)
# All numbers are time in seconds
# default value
# xset dpms 600 600 600 &
# 1 minute blank time
xset dpms 60 60 60 &

# start full screen web app
# change the URL if Roon Web Controller is running on a different system
# set --user-data-dir to restore your login and Home Assistant settings
/usr/bin/chromium --kiosk --user-data-dir=/root/.config/chromium http://server:9330/display/

1. Save and exit
2. Make the kiosk.sh executable
3. chmod +x /root/kiosk.sh
4. reboot

ToDo

• Keep LEDs off

    # Disable the PWR LED
