How to use Nvidia Prime or Bumblebee in 18.04 MSI Laptop

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.

Code:

---

sudo prime-select intel

---

log out and back in>>>or reboot

i did it but nvidia driver is still running :( any fix ?

Did you log out and back in>>>or reboot?
Also what shows for this:

Code:

---

apt policy nvidia-prime

---

This link might add some light: https://github.com/stockmind/dell-xp...espin/issues/8

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.
