In the new version of Ubuntu, I cannot find the application to reverse the color of my screen. It has been in the Ubuntu 10, when I pressed the button Win+M or Win+N, the color of the whole screen would be reserved. What's the name of that application. Can I find it in new version?

Compiz method

Its a Compiz plugin, Firstly install ccsm if you havent already

sudo aptitude install compizconfig-settings-manager

Then go to 

System > Preferences > CompizConfig Settings Manager

Opening CCSM

Tick the plugin Negative. If it is not listed, then install the compiz-plugins package, and reopen CCSM:

sudo apt-get install compiz-plugins

Ticking

Now it should work But in Natty, You will face a problem, Pressing Ctrl+M Brings up the messaging menu So the key association of the Negative Plugin should be reassigned to another combination

To do that: Click the Name of the negative plugin You should encounter such a page Negative Plugin Click the key combinations and change them to something else Clicking Now it will work

Non Compiz method

Either you can use

magnifier -z 1 -fi

or
sudo apt-get install xcalib
/usr/bin/xcalib -invert -alter;

  • @Oxwivi I think so there is a command backend for Compiz.

  • @Amith kk It seems that the negative cannot be enabled after I do what mentioned in this post.

    Also, remember to run sudo apt-get install compiz-plugins in case you don't have the compiz-plugins package already installed for some reason.
