Title:
  Unity sometimes freezes after wake up from suspend

Status in Unity:
  Expired
Status in unity package in Ubuntu:
  Expired

Bug description:
  I couldn't find anything that can cause this, it is completely occasional.
  I use Ubuntu 12.04.2 64bit.
  Sometimes if I open my laptop's lid to wake it up from suspend, my whole desktop freezes. I'm reporting this to unity because with any other DE it doesn't happen (not even with unity-2d).
  In my case, after waking up from suspend, I can see the screen's lats state for like a second, with a notification saying "disconnected from network", but in normal cases, that notification disappears and then everything starts to work, for example nm-applet connects to the wifi-network again etc. But in some cases, the desktop freezes with that first notification on it. Sometimes I cannot even switch to tty1. But when I can, an "export DISPLAY=:0; unity --replace" doesn't help, only a sudo restart lightdm 'solves' the issue.
  No matter what kernel I boot (3.2 or 3.5), this happens sometimes.

  Sorry if it turns out that this is not related to unity, but that
  would be my best guess.

  Thank you in advance!
