# DSKY launcher for Orange Pi
# - Starts `next-dsky` (server + UI) and opens Chromium fullscreen
# - In appliance mode (default): sets up display, black screen until ready
# - Cron mode: re-opens Chromium if it crashed

# Display overrides (env vars, set in ~/.xsession before calling this script):
#   DSKY_XRANDR_OUTPUT     xrandr output name        (default: HDMI-1)

#                          For the 800x480 LCD use:  0,-1,480,1,0,0,0,0,1
