Custom Splash Screen

src

In /boot/config.txt, add:

disable_spash=1

optionally:

disable_overscan=1

In /boot/cmdline.txt, add:

logo.nologo consoleblank=0 loglevel=1 quiet

By hand run

systemctl disable getty@tty1

apt install fbi

Create /etc/systemd/system/splashscreen.service:

[Unit]
Description=Splash screen
DefaultDependencies=no
After=local-fs.target

[Service]
ExecStart=/usr/bin/fbi -d /dev/fb0 --noverbose -a /opt/splash.png
StandardInput=tty
StandardOutput=tty

[Install]
WantedBy=sysinit.target

With /opt/splash.png


Might need to kill fbi when starting the kiosk.

Packages

sudo apt install -y sox espeak mplayer ffmpeg alsa-utils

Sound

Use raspi-config to force audio through the 3.5mm audio jack.

There's an issue with the HDMI 'going to sleep' and cutting off the first two seconds of the audio if nothing is being played through it. The 3.5mm jack seems to not have that issue.


The 3.5mm jack has a lot of noise on the line. The fix looks to be using a USB speaker. For now we'll go with the 3.5mm jack but this will eventually need replacement.

Monitor

To get monitor resolution:

fbset -s
