I'm starting to think that the difference between my laptop at home and
my work machine is not the graphics adapter, it's the fact that I
actively lock my desktop and generally do not on my laptop... the issue
is triggered when I lock the screen with CTRL+ALT+L... the screen never
turns off, until I unlock it... then it panics, turns off, and then back
on again... this does not happen if it is left to do it's own thing.

Perhaps the issue is that the lock screen blocks the power off, and then
everything happens suddenly when it's unlocked.... but if the power off
happens before the lock as it would if you just left it alone, it all
happens correctly.

Title:
  New Lock Screen in 14.04 disables power management

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Triaged

Bug description:
  It appears that there are some power management issues related to the
  new lock screen in 14.04...

  To me, it appears that the screen never goes to sleep while displaying
  the lock screen, yet when I unlock it the screen often immediately
  goes to sleep and is then woken back up because I'm now using it.
