Did you get anywhere with this?

I am trying to get a similar system configure with Debian testing/buster
and not getting anywhere beyond having two monitors on a single card
recognised.  I have three monitors, two on first card and 1 on second
card.  Only the ones of the first card are getting managed by
Xorg.  Although the second card and associated monitor are found by
Xorg, I cannot seem to get Xorg to configure and actually use this third
monitor.

Details follow:

$ dpkg --list '*nouveau*'
libdrm-nouveau2:amd64                2.4.84-2             
xserver-xorg-video-nouveau           1:1.0.15-2           

$ lspci | grep VGA
03:00.0 VGA compatible controller: NVIDIA Corporation GM107GL [Quadro K620] (rev a2)
04:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2)

$ uname -a
Linux xxx 4.13.0-1-amd64 #1 SMP Debian 4.13.4-2 (2017-10-15) x86_64 GNU/Linux

but then nothing is connected to this monitor or this monitor is not
connected to anything...  The strange thing is that the output says that
output DVI-I-1-2 will use the "rotated" monitor section which has
already been assigned to the DVI-I-1 output.

I can post Xorg.0.log as well as my current xorg.conf if anybody is
interested.  Without an xorg-conf at all, I get the same effective
behaviour: two monitors working but third one ignored.

Any suggestions welcome.

Thank you,
