Custom xorg.conf in ubuntu 16.04

Unluckily my monitor not correctly recognized by Xorg and it has never been so the very first thing I always do after a new install is to copy my custom xorg.conf to the directory /etc/X11. It is very basic and looks like

Section "Device"
    Identifier  "Configured Video Device"
EndSection

Section "Monitor"
    Identifier  "asus"
    Vendorname  "Asus"
    Modelname   "VW198S"
    Modeline    "1680x1050" 147.600 1680 1784 1968 2256 1050 1051 1054 1087 -hsync +vsync
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Monitor     "asus"
    Device      "Configured Video Device"
    SubSection "Display"
       Depth    24
       Modes    "1680x1050"
    EndSubSection
 EndSection

This does not work any longer in 16.04: what am I supposed to do?

Solution 1:

The new location seems to be:

/usr/share/X11/xorg.conf

Not sure if that will help though.
