Try driver #3. Purge both nvidia and nouveau drivers from your installation, and ensure kernel cmdline does not include anything to defeat KMS. The result is the modesetting driver integral to the X server should be used automatically unless your nvidia gfxchip is too new or too old.

good hint, haven't even noticed this third way.
Nevertheless, I can't get the X modesetting driver working on my Optimus hardware (HP ZBook 15 G2, hybrid graphics Intel/NVidea), whatever setting I choose in BIOS for Hybrid Graphics (Enabled/Disabled/Auto). Maybe this is beyond the scope of this mailing list, but it might be also important to decide how and when to replace nouveau/nv by this built-in modesetting driver.
I don't think there is yet enough predictability as to which hardware works better with the built-in modesetting driver.
Even if I uninstall xf86-video-nouveau and xf86-video-nv and call mkinitrd the module gets into trouble:
[ 13.343] (II) modesetting: Driver for Modesetting Kernel Drivers: kms ... [ 13.361] (WW) Falling back to old probe method for modesetting [ 13.361] (EE) open /dev/dri/card0: No such file or directory ... [ 13.363] (II) UnloadModule: "modesetting"
I had no /etc/X11/xorg.conf and no extra kernel parameters at all, just to make sure. Did I miss something?
Maybe a key difference between OP's gfx and yours? René Krell composed on 2016-09-30 11:13 (UTC+0200):
Just forgot to mention: I got it working just when disabling Hybrid Graphics in BIOS, but just along with the intel video driver. But I want to activate the NVidia device.
I saw no evidence that the OP was using hybrid gfx. AFAIK, fully functional hybrid video demands special video drivers, Optimus, Bumblebee, Prime, or maybe something else??? -- "The wise are known for their understanding, and pleasant words are persuasive."
