Comment 21 for bug 1767594

Hello guys,
I have an MSI GF63-7RD Gaming Laptop with i7-8750H and NVIDIA GTX-1050Ti.
I am able to install ubuntu 18 on my laptop following the instructions here(https://gist.github.com/mari-linhares/cef4cb3440408e44963d1447a7db5ae0) . But after installation it was always using NVIDIA Graphics and draining the battery so fast. So I tried to change it to Intel HD Graphics in nvidia-prime. I changed it and when I rebooted, everythings broken. The system not loading nvidia drivers at all. Only Intel HD Graphics is working.
