Running Digital Signage on a Raspberry Pi 3 over WiFi through a web browser

Note: I am not sure there is a memory leak with Chromium in kiosk mode. I am testing that now. I have had the pi lock up. I have been experimenting with Firefox but launching from autostart isn’t as fully featured.

Also, I am conceiving of a Pi running over WiFi that can take a power outage an recover automatically.

Steps:

1. Get Hardware - raspberry pi 3 https://smile.amazon.com/CanaKit-Raspberry-Complete-Starter-Kit/dp/B01C6Q2GSY/ref=sr_1_1?s=pc&ie=UTF8&qid=1466021686&sr=1-1-spons&keywords=raspberry+pi+3&psc=1
2. Reset pi user password
3. Enable SSH http://www.instructables.com/id/Use-ssh-to-talk-with-your-Raspberry-Pi/
• SSH over Wifi built in is problematic https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=138631
• Disable wlan power settings: https://discourse.osmc.tv/t/pi-3-wifi-unstable/14171/7
1. sudo iwconfig wlan0 power off
2. sudo iwconfig wlan0 power off to /etc/rc.local
4. Turn of eth0: pluggy wrote:Turn off the eth0 in /etc/network/interfaces . Put a '#' in front of any line to do with eth0.
5. Keep Screen awake from blanking

CODE: SELECT ALL

sudo nano ~/.config/lxsession/LXDE-pi/autostart

add:

CODE: SELECT ALL

@xset s 0 0

@xset s noblank

@xset s noexpose

@xset dpms 0 0 0

Select All (from above code), then right click 'copy', then in '/autostart', 'paste' so it looks like this:

@lxpanel --profile LXDE-pi

@pcmanfm --desktop --profile LXDE-pi

@xscreensaver -no-splash

@xset s 0 0

@xset s noblank

@xset s noexpose

@xset dpms 0 0 0

save with 'Ctrl' + 'x' key, then 'y', then 'enter'

then:

CODE: SELECT ALL

sudo reboot

6. Set Chromium to automatically launch
• sudo nano ~/.config/lxsession/LXDE/autostart
• Add: @chromium-browser --disable-session-crashed-bubble --restore-last-session --kiosk
• Note: I am not sure there is a memory leak with Chromium in kiosk mode.  I am testing that now.  I have had the pi lock up.  I have been experimenting with Firefox but launching from autostart isn’t as fully featured.

• Add these extensions to Chromium: Check out "Remove Scrollbars": https://chrome.google.com/webstore/detail/remove-scrollbars/lkfmjedfjkmfmckgcadelnfjebccjdcf?utm_source=gmail

7. Set Static IP address via MAC address and DHCP
8. Setup cron job to restart at certain time
• sudo crontab -e
• Add this line (here reboots at 11:51pm every night)
• 51 23 * * * /sbin/reboot -n
9. Setup VNC viewer

How to setup remote desktop VNC viewer

steps:

install and set password

- sudo apt-get install x11vnc

- x11vnc -storepasswd

create autostart entry

- cd .config

- mkdir autostart

- cd autostart

- nano x11vnc.desktop

- paste following text:

[Desktop Entry]

Encoding=UTF-8

Type=Application

Name=X11VNC

Comment=

Exec=x11vnc -forever -usepw -display :0 -ultrafilexfer

StartupNotify=false

Terminal=false

Hidden=false

- save and exit (Ctrl-X, Y, <Enter>)

This start x11vnc when lxde starts
