Fedora docs have a pretty good description how to handle connections with Networkmanager on the console.
To connect the raspi to an wifi network (either provided by an on site router, or an access point running on your tablet), I ran:
> nmcli con add con-name nexus7-photobox ifname wlan0 type wifi ssid photobox
> nmcli con modify nexus7-photobox wifi-sec.key-mgmt wpa-psk
> nmcli con modify nexus7-photobox wifi-sec.psk '<your password>'
> nmcli con modify nexus7-photobox ipv4.dns "8.8.8.8 8.8.4.4"
> nmcli con up nexus7-photobox
nmcli dev status will display the current connection state.
If you configure multiple connections, they can have assigned a priority in case multiple of them are available:
nmcli -f autoconnect-priority,name c
nmcli c mod "mypreferred" conn.autoconnect-p 10
nmcli c mod "xfinitywifi" conn.autoconnect-p -10
The available connection are stored at /etc/NetworkManager/system-connections. Don't forget to restart Networkmanager (systemctl restart NetworkManager) after changging files manually.
To add additional fonts for the polaroid caption, use these commands:
fc-list: List available fontsconvert -list font: List available fonts for ImageMagickfc-cache -fv: Run after installing new fonts to/usr/share/fonts/
