Thank you Lluís for your suggestion.
So, I suppose I have to add to xserver.conf a line like this one:

   modeline "1440x900 at 60" 106.47 1440 1520 1672 1904 900 901 904 932 - 
hsync +vsync

How can I explain this to my /etc/nixos/configuration.nix ?
I tryed to look inside the nix scripts in /etc/nixos/nixos but I'm lost.
