Title:
  X stops responding to input after entering idle power saving (screen
  off)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I recently upgraded from 12.04 to 14.04.  Since the upgrade I have
  been having issues with X freezing after the screen enters power
  saving.  The issue did not occur in 12.04.  If I boot up a raring or
  saucy kernel, the issue does not occur.  The 3.13 trusty, and 3.16
  utopic kernels are affected.  It also occured when I tested the latest
  mainline drm-intel-next and utopic-rc kernels.

  Symptoms:
  After waking the screen from power saving/screensaver, the primary display wakes but X stops responding to input (the mouse cursor can still move, but clicking has no effect).  Secondary display does not wake.

  Frequency/conditions:
  Occurs almost every time the screen enters power saving (possibly DPMS issue?)

  When did you first notice it:
  Immediately after upgrading to 14.04

  I followed the suggestions at this URL and tested a few kernels:
  https://wiki.ubuntu.com/X/Troubleshooting/Freeze

  The issue does NOT occur when running these older kernels:
    linux-image-3.8.0-42-generic (3.8.0-42.62~precise1)
    linux-image-3.11.0-24-generic (3.11.0-24.42~precise1)

  The issue does occur when running these kernels:
    linux-image-3.16.0-997-generic (3.16.0-997.201407120342)
    linux-image-3.16.0-031600rc5-generic (3.16.0-031600rc5.201407131735)
    linux-image-3.16.0-3-generic (3.16.0-3.8)
    linux-image-3.13.0-32-generic (3.13.0-32.56)

  Additional notes:
  I have a hybrid Intel/Nvidia GPU model (Nvidia optimus), however the error
  occurs whether or not I have invoked the discrete Nvidia card.

  I am running the most recent BIOS for my system.

  When running the 3.11 saucy kernel I still see error messages in dmesg
  after entering power saving, however X does not freeze.

  dmesg errors:
