NVIDIA driver installation on Debian 8.2

[Liu Gengdai <liugengdai@gmail.com>]

Hi

I'm a debian newbie. I installed latest Debian with xfce on my laptop. I 
used official DVD-ROM. My graphics card is NV Geforce GT 640M LE. I 
installed 360.65 driver for my graphics card following the instructions 
on wiki:
https://wiki.debian.org/NvidiaGraphicsDrivers#Debian_8_.22Jessie.22

The installation process went well. But once I created Xorg server 
configuration file and restarted, I cannot enter xfce. It says there are 
X-window server errors. If I delete the conf file, I can enter. But 
nvidia configuration setting reports the driver is not working.

Can anybody help me? Thank you very much.

Best regards,
Gengdai
