I will be moving to Xubuntu 12.x soon, before the EOL of Ubuntu 10.04. In preparation, I want to learn a few things. One is using xcalib, for inversing. I found this command: xcalib -invert -alter will invert the whole desktop. I am not going to use compiz with Xubuntu, but I presently use a feature of compiz with Ubuntu, for inversing the open pages singularly, much more than the whole desktop. Does xclab allow for doing this also. If so, can someone post back the command? Thanks. </body> </html>
