Dell Inspiron Hybrid Graphics - getting NVIDIA card working

Dell-Inspiron-Ubuntu-Nvidia.txt

sudo apt-get remove nvidia* && sudo apt-get autoremove

This went well, no errors. Then I added a new file, /etc/modprobe.d/nouveau.conf

    blacklist nouveau
    blacklist lbm-nouveau
    options nouveau modeset=0
    alias nouveau off
    alias lbm-nouveau off

sudo reboot
sudo stop lightdm
sudo apt-get install dkms fakeroot build-essential linux-headers-generic
sudo apt-get build-dep nvidia-361
sudo apt-get install nvidia-361
sudo reboot

*Also, remove nomodeset command-line call from Grub!
*Also, note:  using 16.04, linux kernel 4.  Have a feeling this helped over my previous tries with Ubuntu 14.04
