My problems regarding the night light is due to the use of dual graphical cards (optimus technology with nvidia) on my notebook, all I needed to do is to install the latest nvidia driver and it worked on the next reboot.

There are lots of details about that, you can either install bumblebee or nvidia-prime, the latter I currently use. To make usage of that you have to type in your terminal:

sudo apt install nvidia-prime

Take a note, however, that this might be dangerous and you have the chance to get a black screen on the next reboot; in order to fix the problem you just log in another tty (Ctrl+alt+FX where x belongs to [1, 9] and remove everything related to nvidia.
