Over the weekend I had a functional booting RPI-4 using the 19.12 image. I had update the mirrors and even installed the mainline kernel. In the 20.04 release thread I asked if a minimal image will ever be released going forward and Darksky proved a a quick minimal spin.
I broke down my testing area, brought over another 4 imaged a new SD card with the 20.04 minimal image and powered on the Pi, nothing. I moved the SD card from the 19.12 minimal based image didn't boot. Put the SD card in with Ubuntu 19.10 and booted. I then downloaded and imaged the 20.04 xfce image tried again... nothing would display on the monitor. I then tried the kde image, again nothing. I tried the Ubuntu nightly and it booted. Tried to imaging SD card with the 19.12 minimal again it didn't boot. I then tried that card in Pi-4 I had working over the weekend... and no display out.
That last phrase is important as I know what the IP address of the boards should be.
Any ideas? None of my SD cards that I have imaged with Manjaro boot/have video output. While raspbian and ubuntu does boot/have video output. Using the same hardware/power supply/cables and monitor. The only difference is what has been written the the SD card.
I'm at a total loss.
UPDATE: I noticed the lights on the ethernet port where chirping, I can ping the Pi... so it appears as if it boots, just no video out. I also tried using a much older 19.04 minimal image, it boots and gives me video out.
New Update: I see I can ssh into the Pi root@IP and run the installer. I'll see what I can back backtrack from that point.
Solved: Apparently Ubuntu and Rasbian output to both HDMI:0 and HDMI:1 and I was plugging into HDMI:1. I was using those images to test my sanity that my issue was not hardware but with the image. Like they say 85% of statistics are made up and and 99.9% of tech issues exist between the keyboard and the back of the chair.
