DESCRIPTION
The display utility is used to set the content for a visual display, such as the Pimoroni Inky pHAT eInk module. Content is gained from several sources:
- The display_conf settings
- System status
- Input from stdin or a Unix domain socket
- MQTT client and GPS receiver report files (if available)
SYNOPSIS
