How to use Nvidia Prime or Bumblebee in 18.04 MSI Laptop

**ethanamm** · September 14th, 2018

this is my 3rd week using Ubuntu as my main system.
but my laptop has low battery life due to always running Nvidia driver.
i have read many tutorial across the web about how to use Nvidia Prime but i didn't found the solution yet.
i have MSI laptop with gtx1050 gpu and running 396 driver.
I want to know how can i make my Nvidia GPU turns off its power while using Intel mode.
i dont mind manual switching between intel and nvidia mode.
Thanks.

All I know is Nvidia in Ubuntu 18.04 always's going to work even if Intel is the Nvidia-prime selected. The kernel of this version drop the support, or something like that, of Nvidia prime/optimus.
