  Title: Sometimes system turns a black screen when resume from S3 via
  Lid Close

  [Impact]

  Sometimes system turns a black screen when resume from S3 via Lid Close
  It only has cursor on screen but still can switch to tty1.
  Failure rate ~ 1/5

  [Test Case]
  1. install Ubuntu 14.04.2 & 3.19+ kernel and boot to OS
  2. Close the lid
  3. Open the lid
  4. check the display status

  Expected results: System should resume to the log in screen when open
  the lid

  Actual results:
  System sometimes fails to resume back to the log in screen but blackscreen instead.
  (Failure rate~ 1/5)

  [Regression Potential]
  Low. Killing touchscreen mapping after 3 seconds should not affect any other input device.

  Details:

  unity-settings-deamon will call "xinput --map-to-output 11 eDP1" at background,
  and it's being blocked so only cursor will show on screen.

  1. Switch to tty1 when this happen
  2. Login with user account on tty1.
  3. Use "DISPLAY=:0 xrandr " on commandline you'll see it's being blocked.

  Since xinput is being blocked for some unknown reason (in gdb it shows
  polling on xcb_connect_to_fd() in XOpenDisplay() ),

  a possible workaround is to set a timeout for xinput in u-s-d.
