I got a bit further, so I think I've managed to do everything correctly however can not launch the desktop, I assume it should auto launch and it did not so I tried to log in via putty and I can.
When I Googled it said type in launchlxde but it won't open it says cannot open display.
Everything up to this point went OK and installed.

This is what I have done,
Wrote bionic to USB stick.
Boot image.
Log in via putty.
Expand image
Update / upgrade
Add user
Install xorg
Install lxde

Reboot

@hawsey,

The error might be arsing from the fact that you're trying to launch an Xwindows program (LXDE) from your SSH session, rather than from a session attached to your main display.

To specify the main display, try this...
DISPLAY=:0 launchxde

To be honest, I've no idea whether that will work or not - and you might run into further problems with permissions or Xorg/LXDE configuration. Graphical stuff in Linux is not exactly my strong point - in fact, it gives me a headache. If you found that getting to this point took a while, well, brace yourself - the next steps may prove to be even more taxing!

@roobarb / group,

Further to my post of last week, I'm going to attempt a build of Ubuntu Bionic with a 4.x kernel.

I've gone over the instructions at https://github.com/birdslikewires/openframe-kernel and https://github.com/birdslikewires/openframe-linux, but it's not entirely clear to me where the kernel packages I generate (according to the openframe-kernel instructions) come into play in the openframe-linux instructions.

Could you please give me a litlle guidance?

Thank you.

Thank you, I've still not managed to get to a basic desktop but will keep trying. I think I am almost there as my USB stick now says it is launching the desktop and I see the purple Ubuntu logo flash up on screen but it never quite gets there.
I'll try another usb stick tomorrow.
