    If you really want power saving, try bumble bee.There is very good tutorials regarding bumble bee in this forum.
    Thanks for the reply. i saw it on ubuntu forums that it can be switched withing nvidia x server software but its not the case with kali it seems. are they any disadvantages using bumblebee instead of this method ?

    well i haven't really heard anything like that.as far as i know,nvidia driver starts up with xorg server,if you wanna switch then xorg.conf has to be changed and then the xorg server has to be restarted so it uses new config file.

    I haven't used bumblebee,so i don't really know. but bumblebee should be power effeicient since you can turn on/off dGPU like in Windows.
