Public bug reported:
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!
