Cannot change built in display resolution (Ubuntu 16.04)

 I have been frustated since I was not able to setup built in resolution in my Ubuntu 16.04,

it was stuck to 800x600 pixel.

I have tried to change the resolution by following this tutorial, but it did not work.


and finally  I found the solution by following below tutorial :


 in short the solution is to change the following line in the grub file :


I change it to 1920 x 1080 for the resolution and remove the # :


And after that update the grub and reboot the server.

sudo update-grub
sudo reboot
