Title:
  kernel 3.13.0-83 regression : screen resolution not detected

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After upgrade from linux-image-generic-3.13.0-77 to 3.13.0-83 the
  screen resolution is reduced to 1024x768.

  Rebooting in 3.13.0-77 solves the problem.

  The screen is a IIYAMA ProLite E2207WSV, VGA Only, 1680x1050 60Hz
  connected to a Nvidia Graphic card.

  Some more information (with the working version of the kernel).
