So, I installed Fedora-Minimal-33-1.3.aarch64.raw.xz on my RPI4, fully
updated it (05/03/2021) turned on root logins using ssh and turned off
It boots nicely and lets me login etc., until I try and boot without a
monitor on one of the HDMI connectors.
The LEDs cycle around the same patterns repeatedly, including lighting
the Ethernet LEDs.
But I can't login. I assume it is stuck looking for a non-existent
monitor on the HDMI connector.
Any advice, please?
