Title:
  UHD resolution not found when logging in, can select after login

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  After updating from vivid to wily I noticed my screen no longer boots
  in UHD resolution. I can set the resolution during the session, but on
  next login it returns back to full hd. This is a regression from
  vivid, where the resolution worked without problem.

  This happens with different window managers.

  In cinnamon I get an additional error, which is solved by removing
  .config/monitors.xml

  none of the selected modes were compatible with the possible modes:
  Trying modes for CRTC 63
  CRTC 63: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0)
  CRTC 63: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1)
  Trying modes for CRTC 64
  CRTC 64: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0)
  CRTC 64: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1)
  Trying modes for CRTC 65
  CRTC 65: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0)
  CRTC 65: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1)
  Trying modes for CRTC 66
  CRTC 66: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0)
  CRTC 66: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1)

  I'm willing to invest some time in trying to find a solution.
