I have been using xcalib -invert -alter to reverse the colors in my screen. The command works fine with the nouveau driver using the onboard graphics driver. However, when I switch to NVIDIA binary driver version 364, the screen color is not inverted.

My laptop is ASUS ROG-GL552VW. I am using Ubuntu 16.04 with NVIDIA GeForce GTX 960M. If any additional information is useful to fix my problem, I'd be glad to share.

Finally, I wasn't able to make xcalib work. Instead, I installed CompizConfig Settings Manager as instructed in the solution here and started using the shortcuts in CompizConfig Settings Manager -> Accesibility -> Negative. If you cannot see the Negative option, you have to install compiz-plugins:

sudo apt-get install compiz-plugins

This could be an alternative way. I've Ubuntu 16.04, Dell E6410, NVIDIA Corporation GT218M [NVS 3100M], nvidia driver 340.98. This works fine:

xrandr --output VGA-0 --brightness -1

Check for connection name and brightness support using xrandr --verbose

Screen 0: minimum 8 x 8, current 2720 x 900, maximum 8192 x 8192
VGA-0 connected 1440x900+1280+0 (0x250) normal (normal left inverted right x axis y axis) 370mm x 230mm
