When I installed the latest raspbian, I couldn't ssh in.

You could simply restart from scratch with the latest (2017-09-07-raspbian-stretch ) release of Raspbian, which - in response to considerable dismay expressed in these forums - reinstates the 'unpredictable' sequentially numbered identification of network interfaces.

Maybe you should spell out what Operating System, version and date, you are running. I did not advise running startlxde-pi as root.

cp 2017-09-07-raspbian-stretch-lite.img /dev/sde Cp appears to work perfectly for me, is fractionally faster*, and simpler. That's a surprising insight. In case it is specific to your circumstances, what combination of hardware platform, Operating System and microSD writer has been used for this?

I'm so confused; VNC achieves this. You say because the Pi may not be connected to the network, but then just use an Ethernet cable and no network.
Maybe there was no simple implementation of vnc for Raspbian 5 years ago, which is the age of the topic you have chosen to ressurrect.

Re: Pi3 boot problem

I do have a spare 4Gb card I can try flashing to, so I'll do that as a next step.
A 4Gb card is not large enough to write Raspbian-stretch. You could try Raspbian-stretch-lite instead.

Re: Help starting GUI via ssh with RPI2!. so then I can use x2go for rdp connection...

Welcome to the Raspberry Pi forums.

Code: Select all

 startlxde-pi
should start the Raspberry Pi Desktop GUI.

But you will need an x-windows server running on your workstation to render the display. And you will need to have initiated the ssh connection with the X Windows forwarding option enabled.

And have you considered testing the microSD card to ensure it can reliably write/read all of its claimed capacity?
