Not able to invert colors | xcalib -a -i stopped working

[harsh-a1]

I used the command xcalib to invert the colors on my screen and it was working fine for a long time till suddenly somehow it stopped working.I am unable to diagnose as to what has caused this.

Now when I run the command it has no effect on the screen and I get the following message :

xcalib -i -a
Warning - Unable to get display calibration

What could have gone wrong? Could this be a bug?

Following is the output of "xcalib -i -a -v" command -
