I run the board headless, using only the serial console, quite a bit -
so it is possible.  Not sure how you are trying to run headless, but the
firmware will output information to the serial port, and assuming you
have your Linux distro setup correctly (usually by adding
`console=ttyS0,115200 console=tty0` to your kernel boot parameters, but
I'm unfamiliar with how Ubuntu does it for sure), you should get serial
console data out.  Not entirely sure what you are seeing, but if you are
running headless can you confirm your setup with your serial port?
