Using 635M Nvidia via Bumblebee on Ubuntu 12.10 64bit

After installing and re-installing the drivers multiple times the following order and packages worked for me. (Basically donig the same as most blogs advise but loaded the Nvidia current updates and configured Bumblebee to use it)

sudo apt-get install bumblebee bumblebee-nvidia linux-headers-generic

sudo apt-get install nvidia-current-updates

then edit /etc/bumblebee/bumblebee.conf

gedit /etc/bumblebee/bumblebee.conf
Driver=nvidia
KernelDriver=nvidia-current-updates
LibraryPath=/usr/lib/nvidia-current-updates:/usr/lib32/nvidia-current-updates
XorgModulePath=/usr/lib/nvidia-current-updates/xorg,/usr/lib/xorg/modules

reboot and test
