How to perform first install on Raspberry Pi 3 without HDMI?

Hi,

I’ve just installed Ubuntu Mate LTS on the SDHC of my brand new Raspberry Pi 3. But I’m stuck…

I previously installed many RasPi 2 with RaspBian distro, and PuTTy was my best friend. I recently tested the latest RaspBian on the RasPi 3 : you first need a PuTTy-like tool to operate then Real VNC can be used to enable graphical display.

But I really don’t know how to proceed with Ubuntu Mate.

I can’t connect via PuTTy because I have no credentials.
I also need credentials for VNC session.
Real VNC connection is refused.
I have no HDMI device.
As I used Win32DiskManager to write an ISO file, I’ve not been asked for persistent write / install.

How could I proceed to make the first install ?

Thanx for help.

You won’t have the opportunity to connect from outside until you’ve done the basic install so-

  1. you need to have the cables and whatever to hook a display, so you can see what is happening. The 1B+, 2, 3 series of Pi all use the 4 connector 2.5mm jack for both audio and video - so you need to sort out which does what.
  2. you may then need to edit config.txt to convince the setup to use your display (NTSC/PAL etc).
  3. possibly you have need of a headless server configuration about which I think there was a forum question.
