Note that there is currently no proper support for LMTX in PGF/TikZ.

mtxrun --generate

and you ned to use use m-tikz.mk* from the distribution

How did you install TikZ? The error message seems to suggest that tikz module is not installed. You can check by looking at the output of 

mtxrun t-pgf.tex

On my system, that gives:

/opt/luametatex/texmf-modules/tex/context/pgf/basiclayer/t-pgf.tex

(which I had installed the texmf-modules tree by copying from the context standalone tree.

By putting them in the right location in the tree (somewhere inside $TEXMF/tex/context ...).

Interesting... it seems that only a few features don't work. I regularly use pgfplots, and haven't noticed any compatibility issues in my examples.

What will be needed to add a LMTX "driver" for TikZ? Porting pgfsys-luatex.def to pgfsys-luametatex.def? Or is something else also needed?

Nowdays exagerating remarks like "lots of ..." just like "many buge ..." 
and "completely broken ..." and some more make me put something at the 
bottom of my list cq. dismiss.

I don't know. If you send me the examplex that don't work I can check 
it. I suppose that it there is a well defined interface layer we can 
provide the connection and maintain that in the context distribution. 
And we can also just decide that some features are not supported (for 
instance because they interfere with context resource management).

Yes, there would have to be a pgfsys-luametatex.def and some detection
code to switch the driver appropriately but that latter part is easy.
I'm not too sure what is needed for the former though for LMTX.

When I last looked at it about a year ago it was completely unusable
with the LuaTeX driver because position tracking primitives were
removed (\pdflastxpos, \pdflastypos) and box keywords had changed
(\hbox dir TRT). Some catcode trickery in pgfplots also had stopped
working (https://github.com/pgf-tikz/pgfplots/pull/353).

As Hans mentioned in another message, the PDF resource management has
changed (if I understand it correctly), so things like shadings and
patterns would have to be adjusted.

Cheers, Henri

keep in mind that luatex has no \pdf prefixes (i added these for usage 
like tikz but we have other ones in context)

in context we always used the 'direction' keyword because when we 
dropped many directions from luatex these weird three letter ones made 
no sense (basically they were sort of used as three constructor elements 
but that model was already dropped)

anyway, as i mentioned, somehow the intenet triggers exageration: 
'competely unueable' is also one of these 'move to bottom of todo list' 
things

nothing changed there (also because we never really used the engines 
stuff) ut any resource managament has to be intercaces to any macro package

that said: i have a few tikz test files and when they run ok it's fine 
for me ... if something fails users can ask on the list (with a mnew) 
and when they don't ... no reason to complain
