After some point, I start having to remove /etc/X11/xorg.conf in order to move forward from "Booting without full network configuration". Thus what I do every time I reboot my Ubuntu is to login in safe mode, remove xorg.conf and reboot. Does anyone have any idea? Thank you so much.

$ dpkg -p xserver-xorg

xorg.conf looks like this:
