Comment 9 for bug 1252121

I just modified /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service in the way you asked. Then I suspended using the Unity menu. However, the laptop never turned off (usually it does after 20-30s) - at least not for over a minute. So I pressed I key and was able to login (and post this). However, the network was already gone (without suspend!). The reason is in the log file:
env: annotate-output: No such file or directory

So I ran "sudo apt-get install devscripts" and retried. See the logfiles attached.
