Inverted colours on Firefox Ubuntu?

[Youbuntoo44]

Heyy guys I dropped something on my keyboard, it hit some buttons and now my Firefox window's colours are totally inverted! It's awesome and I wanna know the key combination to doing this and how to Un-Invert it back. I have a video on Youtube of this behavior... http://www.youtube.com/watch?v=YVZ4iGxKS1Y

Oo I figured it out guys It's Windows logo+M for all windows and +N for a single window.

That was totally weird and scared the crap out of me. Thanks for figuring this out.

This is actually a Compiz feature... very helpful for working at night.

oh, :) Is that what its for? I haven't realised, I just thought it was just another one of those pointless things for show

Install compiz setting manager for more such effects.

it's not just a compiz feature, if you have a better video card, the system will enable extra desktop effects (System->Preferences->Appereance->Visual effects)
this extra effect it's good when it's dark :)
windows key+M = invert ALL your colours
windows key+N = invert JUST your active windows' colors

Yes, and that means exactly that it's a Compiz feature. The "desktop effects" is Compiz.

Anyway, the purpose of this feature is that many people find white text on black background easier on eyes, even more so when working in dimly lit environments. While using a dark theme helps a bit, most of the web paes, for example, still use white background and black text. Changing to negative colors solves this.

Hello,

i have now 11.04 Ubuntu (fresh install). On Firefox and Thunderbird some images looks weird like this:

There is no problem when i view same page with Opera or Chromium.

Do you guys think that reinstalling firefox and thunderbird should help or is it something in settings?

Thanks.

Dat gummit! I just accidentally did this and thought my video card and dweebed out on me! I took a screeny to post on here, but it was normal, so I knew another pesky keybind had reared it's ugly head! Thanks for posting this... whew.

I am having a similar issue. It is affecting SOME (10%) images in firefox. Thus far it looks like it is only firefox. I just got this laptop, and I installed 11.04 on it. Some pages it displays everything inverted, some pages just a few images. The attached pic is a screenshot of this thread showing one pic inverted, and one not. Tried every shortcut I can think of. Please help...
