balena-pihole: Problems after FBCP changes

Hi there,

I’m having a couple of issues that I believe started after the recent FBCP changes. I can’t be 100% sure because they problems didn’t actually appear until after a power cycle (recent power issues in TX).

I’m having two issues:

1. My LCD no longer displays anything (black screen). This is the official RPi touch screen with the same configuration that I’ve had in Balena for a couple of years.

The only related thing in the logs is this.

18.02.21 16:35:40 (-0600)  fbcp  WARNING: FBCP_DISPLAY variable not set.
18.02.21 16:31:29 (-0600)  fbcp   Set the value if you are using an SPI-based display.
18.02.21 16:31:29 (-0600)  fbcp  Idling...

There are so many different guides/posts out there about LCD screens, so I hesitate to change anything that was working until I have some idea of where to go, but I have tried setting FBCP_DISPLAY to adafruit-hx8357d-pitft and ````adafruit-ili9341-pitft``` to no avail.

Again, I’ve got the “Official Raspberry Pi 7-inch display” so I don’t even know if this is required. My other settings more or less match what Chris posted here.

1. This issue depends on what my above settings are. By default (before I started trying to get the display working), all services start and everything looks ok, but pihole does not respond to DNS queries until I restart the container. No issues in the log.

This has happened to me before, btw - years ago when display settings were all over the map, I would have to manually restart the pihole container after a device reboot so that it would work. I don’t remember what ended up resolving the issue, likely fixing the display.

Please let me know if I can share any other settings or logs.

Thanks! Roddie
