It just stopped working. After I boot Ubuntu it does not work. When I run unity --replace it works again, but after restart problem occurs again. And that happens on every reboot. I have some startup apps, but I don't think that can be the problem.

Any idea?

UPDATE:

Looks like I had some problems with firefox causing Alt+Tab to stop working. After reinstalling firefox and computer restart it works.
