I'm new to Ubuntu, so I apologise up front for me being a bother...
Anyway, my problem:
I recently did some editing, using compiz (or I think that's how it's called).
Now there's nothing in the top bar any more (time, sound, internet, etc) it just tells me what program I'm using.
I also no longer have sound, nor does my microphone work anymore (tried skyping, failed horribly).
Here's a screenshot of the problem:
I hope you can help me,
