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.

Problem is X setup and its interaction with desktops. I have two VGAs: * intel embedded in my i7 CPU * external NVidia GTX770 Each of them drives 2 monitors for a grand total of 4. I managed to have partial victory in the sense: I can have dual monitor using *either* intel *or* nvidia or I can have all four, but then gnome crashes somehow ("Oh no! Something went wrong...") while X is ok. In the "working" cases xrandr dees only the two active monitors. I also installed Xfce which works happily with the same config where Gnome crashes, but shows only the nvidia monitors with mirroring and xrandr does not work at all. I am now writing from Win7 (with all monitors correctly working!) and thus I have no access to actual files. Can someone point me in the right direction, please?Use at least Debian 8, for a start.
