Comment 12 for bug 980298

Well, all the nux packages came down on main finally
but that made little difference, and unity plugin became disabled
so I reset everything as is on my working installs, compiz still crashed.

So I uninstalled nvidia-current and lo and behold I was able to log into
Unity 3-D Then just to make sure that was the culpert I reinstalled nv-current
and sure enough compiz and unity broken again.
Uninstalled again and have a working unity desktop.

Not entirely satisfactory, but hey, it's working for now.
Will be keeping an eye on things as they progress.
