I’m trying to set up a headless device and cannot get the system to boot without a display plugged in. I can boot the device with a display attached, unplug the display, and SSH in as normal; but if I turn the device on without the display plugged in, I can’t connect via SSH, and plugging the display in shows nothing but a black screen. I’ve tried disabling xserver
, but that had no effect.
Here’s the latest version of my configuration:
# Edit this configuration file to define what should be installed on
# your system. Help is available in the configuration.nix(5) man page
# and in the NixOS manual (accessible by running ‘nixos-help’).
