2. Install unattended upgrades
sudo apt install unattended-upgrades -y

sudo nano /etc/apt/apt.conf.d/50unattended-upgrades
add to
Unattended-Upgrade::Origins-Pattern {

"origin=Raspbian,codename=${distro_codename},label=Raspbian";
"origin=Raspberry Pi Foundation,codename=${distro_codename},label=Raspberry Pi Foundation";
"o=Syncthing";

run sed

sudo sed -i 's/^\/\/Unattended-Upgrade::Automatic-Reboot "false";/Unattended-Upgrade::Automatic-Reboot "true";/g' /etc/apt/apt.conf.d/50unattended-upgrades
sudo sed -i 's/^\/\/Unattended-Upgrade::Automatic-Reboot-Time "02:00";/Unattended-Upgrade::Automatic-Reboot-Time "02:00";/g' /etc/apt/apt.conf.d/50unattended-upgrades

2. update system
sudo apt update && sudo apt dist-upgrade -y

3. Install feh
install the dependencies:
sudo apt install libcurl4-openssl-dev libx11-dev libxt-dev libimlib2-dev libxinerama-dev libjpeg-progs libexif-dev libheif-dev libimlib2-dev libde265-dev -y

check out the git version:
git clone https://git.finalrewind.org/feh
cd feh

Now, compile and install feh:
make -j4 curl=1 xinerama=1 verscmp=1 exif=1
sudo make install

https://feh.finalrewind.org/
4. enable HEIC support

git clone https://github.com/vi/imlib2-heic.git
make
sudo make install

https://github.com/vi/imlib2-heic
3. Setup Wireless

place wpa_supplicant.conf in boot with EOL in unix style

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

https://www.raspberrycoulis.co.uk/hints-tips/raspberry-pi-multiple-wifi-networks/

4. Create directories
mkdir -p /home/pi/photos-copy

5b. setup ssh-copy-id
Copy your public key to your Raspberry Pi

ssh-copy-id <USERNAME>@<IP-ADDRESS>

https://www.raspberrypi.org/documentation/remote-access/ssh/passwordless.md

6. Install Syncthing
wget -O - https://syncthing.net/release-key.txt | sudo apt-key add -
echo "deb http://apt.syncthing.net/ syncthing release" | sudo tee -a /etc/apt/sources.list.d/syncthing-release.list
sudo apt update
sudo apt install syncthing -y

Create config files by running 'syncthing"
then Kill the syncthing process with Ctrl+C in the Terminal

create systemd entry (look @ pimylifeup)
sudo nano /lib/systemd/system/syncthing.service

[Unit]
Description=Syncthing - Open Source Continuous File Synchronization
Documentation=man:syncthing(1)

autostart syncthing
sudo systemctl enable syncthing@pi.service

4. Setup .xsession / feh

.xsession

# disable screensaver
xset s noblank
xset s off
xset -dpms

# use PIR sensor to turn on/off display
# /home/pi/pir-control.py &

# start slideshow
feh --auto-rotate -d -F -r -Z -z -R 3600 -D 30 photos-copy/

https://www.splitbrain.org/blog/2018-05/12-diy_digital_picture_frame

run raspi-config to adjust locales and boot into desktop (must auto-login) by default

5. Turn the monitor on and off automatically (optional)

wget https://gist.githubusercontent.com/SirCrocker/937d06f8f2c1227a83802b9b77f60ba0/raw/3f9c9558d7d15dfdb035e77bc6a77ad0d1abd5ea/rpi-hdmi-tv.sh

sudo apt-get install cec-utils -y

To turn the monitor on/off on a daily schedule, grab this script and put it in /home/pi/rpi-hdmi.sh. Next, make it executable:

chmod +x /home/pi/rpi-hdmi-tv.sh

Add a cron entry to call this script at the desired time

crontab -e

And add the following lines at the bottom of the file:

# Turn HDMI Off (21:30)
30 21 * * * /home/pi/rpi-hdmi.sh off >/dev/null 2>&1

# Turn HDMI On (9:00/9:00am)
0 9 * * * /home/pi/rpi-hdmi.sh on >/dev/null 2>&1

vcgencmd  works. the other will turn off the monitor but wont show anything when turning it back on
