That sounds like you have an Nvidia Optimus-enabled system. Unless you
are able to disable your intel or nvidia gpu via a BIOS setting,
you'll have both your intel and nvidia gpu enabled, but your intel gpu
will be the one driving your main display, not nvidia. Installing the
proprietary driver (with no additional configuration) will not change
this (and a nvidia-xconfig generated xorg.conf would be broken for

Your options include:
- just using your intel gpu and forgetting about your nvidia card
because optimus is still kind of a mess on linux
- installing and using bumblebee [1] - perhaps the easiest because
Debian has bumblebee packages
- sticking with nouveau and using PRIME [2]
- using nvidia-prime [3]
