therefore, i had to reset my box and enter recovery mode and choose xfix in order to be able to log into my account graphically.

but it is obvious that my box is not using nvidia driver rather default linux graphic driver eventhough i have disabled "nv nvidia" in /etc/default/linux-restricted-modules-common. here is the xorg.conf:
