Files on the Pi

Where Pi Display keeps its program, settings, and media.

Path What
/usr/local/bin/pi-display The installed program
/etc/pi-display/config.json Media folder, SMB login, and settings from setup. Readable only by the user the slideshow runs as.
/etc/systemd/system/pi-display.service The service that starts the slideshow at boot
/var/lib/pi-display/media The mirrored copy of an SMB or Drive folder
/var/lib/pi-display/override A pi-display on or off override and when it ends
/usr/share/plymouth/themes/pi-display The boot logo, on Pis with the boot splash

Setup also installs mpv and v4l-utils (for HDMI-CEC TV control) with apt, and may switch the Pi to boot to the console instead of a desktop. Uninstall covers undoing both.
