Title:
  14.04. Resume from suspend with HDMI display, login/lock screen
  freezes.

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Hello friends. I have a Dell Latitude E7440 that came with Ubuntu on
  it. I am running 14.04.1 with all available updates as of today. I
  noticed if my laptop is in suspend mode and I plug in an HDMI monitor,
  then open the lid to resume, it freezes. The lock screen allows me to
  move my cursor around, but I cannot click anything, and the keyboard
  itself does not respond whatsoever.

  If I do these steps in any sort of different order, as in resume
  laptop first then plug in, etc., it's fine. It's just when the system
  is resuming with a new HDMI source plugged in that wasn't there when
  it went to sleep.

  Thank you for your time, dedication, and hard work!
