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/
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:

The issue does NOT occur when running these older kernels:

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.
