Bug description:
  SRU Request:

  [Impact]
  Some systems don't play well when the dGPU is disabled. It should still be 
possible to use the Intel iGPU without disabling the dGPU.

  [Test Case]
  1) Enable the -proposed repository, and install the new 
"ubuntu-drivers-common"

  2) Make sure the nvidia packages are installed, and enable power saving mode:
  sudo prime-select intel

  3) Restart your computer and attach your /var/log/gpu-manager.log. see
  if the system boots correctly. If unsure, please attach your /var/log
  /gpu-manager.log and /var/log/Xorg.0.log

  4) Install the mesa-utils package:
  sudo apt install mesa-utils

  5) Check the output of the following command (which should mention Intel):
  glxinfo | grep OpenGL

  
  [Regression Potential]
  Low, as the feature is disabled by default. This is only for hardware 
specific workarounds.
