I run Debian 8 Jessie on my Sony Vaio Laptop. It has an Nvidia Geforce GT 640M LE graphics chip.
I followed the official Debian Wiki article to install nvidia-drivers instead of nouveau:
https://wiki.debian.org/NvidiaGraphicsDrivers
Now I am running Nvidia Driver 352.79 which should be compatible to my GPU according to the mentioned wiki pages.
After the installation I ran nvidia-xconfig which created an /etc/X11/xorg.conf for me automatically:

Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"

The problem is when I boot up, I do not get to see the desktop environment - here is the complete Xorg.0.log:
