I've had something really weird happen to my 12.04. I was installing new desktop environments, and now I have no sound through my headphones and the "pop up" theme has changed. by pop up, I mean the icons that appear when I use hot keys to do things like change volume, brightness, etc.

I first noticed this change after I left my computer on, but was away from it. I hadn't logged out of my session, but the theme changed when I woke back up from suspend. The only other thing I had done was the regular update stuff with update manager.

So, the question is how do I go back to how it was this morning? At the very least, I can deal with the icons being different, but I need sound out my headphone jack! here's a pic

What desktop environments did you install? – Seth Feb 2 '13 at 2:55
XFCE, Awesome, and I already had Cinnamon. I've since purged them. – jayb151 Feb 2 '13 at 3:06
Okay, that's a start. Could you post a screenshot of the notifications? That would help a lot. – Seth Feb 2 '13 at 3:13
I'm really sorry for being such a n00b, but where do I find the current notifications. I'm just using the standard unity DE – jayb151 Feb 2 '13 at 3:35
I'm sorry, I meant the "pop-ups". They are called "notifications" :) – Seth Feb 2 '13 at 3:37

I found the answer to the problem! I uninstalled all XFCE stuff using the terminal command found at this page: Remove XFCE. It completely fixed the problem! Headphone is back, and the theme went back to normal!

Thanks for the help anyway!

Yeah, this was a problem with new desktop environments overwriting the default applications for things with their own custom applications. I'm glad you fixed it :) – Seth Feb 3 '13 at 6:07
