I am currently on "stretch" (testing).
Same behavior.
I seem unable to activate two cards at the same time.
With no /etc/X11/xorg.config I see the internal (Intel) card (no signal on nvidia monitors).
If I add explicit NVidia setup then the other two monitors come to life *after login*; gdm3 always displays on the intel monitors; after login the intel monitors go dark (but they have syncs).
I can't be more precise at the moment because I'm on Win7.
