I'm working on a project using a NanoPi Neo with OLED display, using the stock Ubuntu OLED image provided with the device. I'm trying to find which file is used upon boot to display information on the display.

I assumed it was: /NanoHatOLED/BakeBit/Software/Python/bakebit_nanohat_oled.py

However after making changes to this file they are not shown upon rebooting the device, which leads me to believe the file is elsewhere.
