I've noticed several issues with Ubuntu 16.04 LTS (64-bits) and my Nvidia drivers. I have an Acer V-Nitro7 with a Intel® HD Graphics 530 (Skylake GT2) and Nvidia GTX 960M.

Two major issues

  • One is that the PC freezes and crashes (I must force reboot, nothing else to do) during 3D utilisation such as games.
  • The other one is that the scrolling is not smooth, unfortunately I could'nt explain it with my own words, so the best example I have is when, in graphic settings, V-Sync is not working properly, a line on the screen stays for about half a second before disappearing. I have this same issue when I scroll down/top on browsers and everything else. (basically it's not smooth)

This wasn't the case when I first installed Ubuntu, that's why I believe there are issues with the installed drivers.

I remember having a lot of troubles for the sames issues on Windows 10, that I solved after someone on Nvidia forums told me to never update the drivers on laptops, and only use the driver provided by the manufacturer website. Which I did and it worked fine since then.

Now, on Additional Drivers I have

- NVidia binary driver - 361.42 from nvidia-361 ....
- X.Org X server ....

On games, using NVidia driver (low or ultra quality), PC freezes and crash. Using the other one (I guess it uses Intel graphics ?), it doesn't freeze/crash on low quality, but obviously it's an awful quality.

I've searched on lots of threads for Ubuntu and Nvidia drivers, but since i'm novice to Linux, I wouldn't want to mess up with drivers that could do more bad than good for my case.

Quick question : Are Windows and Linux NVidia's drivers build numbers the same ? In that case should I look for the same driver that I was using on Windows ? (which I think was 359 or something)

I know Ubuntu is not the best way to play games, but I'm sure there's a way to fix it. I'd be grateful if someone could help me find the right driver for my case.

Linux and Windows Driver build Numbers are generally different. SkyLake architecture is a very new processor architecture and still not very well supported under Linux in General. I mean your laptop has Hybrid Graphics which is generally not very well supported under Linux. There are ways you could Improve the situation. I recommend that you Install Bumblebee and nvidia drivers on your Laptop with Ubuntu. So what you can do then is that you can choose to run a particular application on your Nvidia Graphics Card and use a primusrun from terminal to launch your application. For example if you wanted to launch firefox from your nvidia card you could use primusrun firefox and the firefox instance you launch this way would launch from your Nvidia Card. All other applications would launch normally from the Intel Card.

This way you will not have any screen tearing because you are running on Intel Graphics all the time and only the applications which require more GPU power are manually launched from Nvidia Card. This way there will be no screen tearing etc. and you can enjoy the power of Ubuntu.

I have answered this process for installing bumblebee in a few other questions on Ask Ubuntu forums already. However for your convenience you can got to.https://rajat-osgyan.blogspot.in/2016/04/how-to-install-latest-nvidia-drivers-on.html

for understanding the complete process. Again I am not trying to promote my blog, I have already explained this process once before on Ask UBunt. Below is the reference question.
