How to install NVIDIA GTX 950M driver in Ubuntu 18.04 LTS

Im using Ubuntu 18.04 LTS and GTX 950m I'm already installing GTX 950m driver, but when I check with lspci -k | grep -EA2 'VGA|3D', I see:

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530
(rev 06)
Subsystem: ASUSTeK Computer Inc. HD Graphics 530
Kernel driver in use: i915
--
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 950M]
(rev a2)
Subsystem: ASUSTeK Computer Inc. GM107M [GeForce GTX 950M]
Kernel driver in use: nvidia

I can see Kernel driver in use: i915, I want to change i915 to nvidia, because I think my Ubuntu use Intel Graphics (i915) although I was installed NVIDIA driver

UPDATE 1: I accessed a link, and I see my Ubuntu use NVIDIA. But I have 2 boots: Window 10 and Ubuntu 18.04. When I use Ubuntu I feel colors were not rights (it's mean colors between Ubuntu 18.04 and Window 10 it not same, color of Window 10 better than Ubuntu 18.04), and when I play a website game in Ubuntu, very lag ( my internet is good, it's no problem), so I think my VGU (FPS) very low, and to use NVIDIA play the web game, does it happen?

It looks liek you have hybrid graphics in your laptop. There are two video adapters Intel and Nvidia. The i915 driver is for Intel.

When you run in terminal

lspci -knn | grep -EA2 'VGA|3D'

you see both adapters (intel and nvidia).

Now follow this tutorial to pick which one you want to use
