I think I've run into the same or at least a very similar issue (see
https://bugs.debian.org/1040254, reported against
xserver-xorg-video-nouveau) and my fix was (unfortunately) to switch
from xserver-xorg-video-nouveau to the non-free binary-only driver
xserver-xorg-video-nvidia with nvidia-kernel-dkms.

(Using nvidia-open-kernel-dkms instead of nvidia-kernel-dkms did not
suffice for me as it had other issues, it made X show up on only one
screen and without any xrandr or nvidia-settings capabilities.)

HTH
