That's what I did and it simply didn't work for a Ubuntu based image.

Most configuration switches for live-build script are not supported under Ubuntu and well, I don't remember every bits of what were working or not because I tried monthes ago but it was to tricky and except for Debian, it was simply unusable as is.
As for the git repos, I tried many combinations and nothing worked as expected so I basicaly decided to do this by hand and take inspiration from the howto on what to install/tweak.

I ended with something that was not that complicated to do, scriptable (mostly) and working (except for this dual head stuff) so I stopped going the Live Build way, at least, just the time to sort out things and get back with some contributions on that part.

You could probably set up a Debian changeroot using debootstrap 
(admittedly, I've never tried that, though), or a virtual machine with 
Debian as a dedicated build host. 

> Second : sorry to say that but the live build process documentation is pretty partial and based on situation where "it works" but outside that scope a lot of things "just don't work" and there are many forks for the setup scripts from many users so to be honest ... this is a bit messy and since there is nothing in the repo but everything in personnal github here and there, it was just to complicated 

Are you talking about the live-build project's documentation, or the 
X2Go-TCE-Live documentation? 

If all you want to do is build X2Go-TCE-Live images, you don't need to 
start by reading and trying to understand the live-build project's docs. 

Read our Wiki page: 
<https://wiki.x2go.org/doku.php/doc:howto:tce#starting_the_build>, run 
the three chunks of code given in the sections titled "Configuring the 
Build", "Live-Patching the Build", "Starting the Build", and you end up 
with a stable, i386 build ready for netbooting via PXE, TFTP, HTTP. 

Prefer one that boots from local/portable media? 
Change 
export LBX2GO_IMAGETYPE='netboot' 
to 
export LBX2GO_IMAGETYPE='iso-hybrid' 
in the first chunk of code, and you're done. Can't get much easier than 
that, can it? 

Kind Regards, 
Stefan Baur
