DP-MST support was first added to nouveau for precisely these kinds of
setups. It does, generally, work, so that means there's something
extra-special about your setup.

Or it has something to do with the I2C-bus, that seems to be used by some docks (AUX I2C)? Nothing is found on the i2c-busses provided by nouveau.

I'm not sure what NvI2C does anymore, but you probably don't want it.
Also nouveau.mst isn't a think anymore (it might have been for a few
releases while we weren't sure about it working).

This is the DP connector.

I think it may be interesting to boot with
drm.debug=0x1e nouveau.debug=i2c=trace,aux=trace,disp=trace
Also, after everything boots up, can you look at what "grep .
/sys/class/drm/*-*/status" produces?
I suspect figuring this out will require some amount of back and
forth, and I'm not really the best person for display issues. Try
#nouveau on irc.freenode.net on a week day.
Cheers,
