Dell Vostro 3250 xorg.conf

With Mint 18 display settings are working out of box, but in Mint 17.2 is needed to install packages linux-image-extra-4.4.0-36-generic and linux-image-4.4.0-36-generic and linux-headers-4.4.0-36 and linux-headers-4.4.0-36-generic

After installing the new kernel you need to make an /etc/X11/xorg.conf file via recovery mode or by hand.

1. Method Xorg -configure
– boot to the recovery mode and drop to the root prompt and run
mount -o remount,rw /
Xorg -configure
cp /root/ /etc/X11/xorg.conf

2. Method by hand
gksu pluma /etc/X11/xorg.conf
… the contents -> xorg.conf

… save and quit
