Black and white on my screen flipped

[mariourk]

Somehow I managed to flip the black and white in my screen. All the stuff that is normally projected in white is now black. And everything that is normally black (like text, for example) is now projected in white.

I suppose this is some kind of feature that is triggered by some key combination. The question is, how do I set it back to the normal setting?

Thanks anyway :)

<Super+N> or <Super+M> will turn your desktop back to normal.

*Super = Meta = Win

It's a Compiz-Fussion plugin called Negative. You can find it under CompizConfig Settings Manager in your menu or running "ccsm", where you can also configure or disable it.
