[Bug 1767594] Re: Ubuntu-18.04 Installation/Upgrade freezes/does not work.

[Bhanu]

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.

Title:
  Ubuntu-18.04 Installation/Upgrade freezes/does not work.

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  Hello all!

  I have been tirelessly trying to install Ubuntu-18.04 since the last 2
  days, but every attempt turned out to be negative. Apart from other
  GUI based problems, which I am reporting here.

  When mounting the iso using the inbuilt Disk Image Mounter utility,
  and attempting the GUI base upgrade method (from within
  Ubuntu-16.04.1), I get a pop-up saying "Oops! There was a problem
  running this software. Unable to locate the program".

  When mounting the iso and attempting an upgrade through the terminal,
  the "gksu sh /cdrom/cdromupgrade" command leads to a blurred screen
  prompting for the password and then does nothing. Replacing gksu with
  sudo returns "cdromupgrade command not found".

  When booting from a live flash drive (created from the same iso), the
  installation freezes at the network page after I enter the password
  for my wifi. When using a wired connection, the network page does not
  appear. The installation freezes at the page where it asks for Normal
  or Minimal installation. It even has options for Install Updates and
  install Third-Party Drivers etc (the 3rd page of the installation). I
  have tried different combinations of options, but the installation
  never proceeds further. Sometimes, it even freezes at the keyboard
  selection page (the 2nd page of the setup).

  I have already verified the integrity of the downloaded iso through a
  checksum verification. It is perfectly OK.

  Current OS: Ubuntu-16.04.1 (latest kernel, as per apt-get)
  Machine: MSI GV62 7RD
