i have UBUNTU 16.04 (had 18.04 with the same problem), and the problem is, when I select intel graphics by sudo prime-select intel
, my system fails to boot. It starts booting, Ubuntu loading animation appears, then it throws me back to a boot console, where underscore is blinking and then it stops blinking, which as I think is a system crash.
I can't use my tty (any of them), i downloaded the drivers for intel graphics, but it makes no difference. And also i've installed nvidia drivers (396) and bumblebee.
I have only 2 ways to load system with intel graphics:
nomodeset
in grub loader, which makes my screen 640x480, but still manages to bootacpi=off
in grub loader, which turns off my touchpad, but works as well.
I am an user of ASUS FX503VD laptop with Intel Core i5-7300HQ and NVIDIA GTX 1050 (4gb).
Any help will be appreciated.
