Activating second monitor with nvidia-settings/twinview crashes unity/compiz

[Christian Theune]

Just guessing that this might be a compiz issue.

When activating a second monitor I regularly find compiz (and/or unity) crashing leaving me with no window manager. Happens quite frequently. Sometimes it works.

Once it's broken I restart lightdm, login and try again. Usually it works after trying a few times.

Sorry for not following up - have been on holidays. However, after applying latest updates this doesn't happen anymore.
