(ARCHIVED) Ubuntu Xenial Image (BSP Kernel)

[sihil]

Hi all,

I've observed a weird issue with the xenial-pine64-bspkernel-20161218-1.img image whilst trying to get it to run headless on my Pine64. Based on an evening of flashing and re-flashing SD cards I have concluded that:

• If an HDMI display is connected on the first ever boot then it seems that the OS will NEVER boot without an HDMI display. 
  
• If NO HDMI display is connected on the first ever boot then the OS will boot happily - with or without a display for ever more.
  

This has tripped me up on an OpenHABian derivative image that exhibits the same behaviour (see issue at https://github.com/openhab/openhabian/issues/105).

I figure there is a script that is running on the first ever boot that sets a piece of configuration differently depending on whether a display is connected or not. Thus far I've not figured out what that is or how to fix it so that a system booted with HDMI the first time can later be booted headless.

Sadly I do not have a serial cable for my P64 so am unable to see the console and figure out what's happening.

Sounds suspiciously like unintended behaviour - if anyone has any suggestions then I'd be glad to hear them.

Many thanks,
Simon
