12.04 - Nvidia GTX 765M with Optimus Unclamed

I have tried alot of different ways to get my pc working with graphics card but hasnt got me anywhere.
I started off with installing ubuntu 12.04 for the first time which left me stuck at black login screen. (solved now).

I have tried bubmlebee method and installing driver from Nvidia directly but both didnt work. (I’ve got removed Nvidia* now since it didnt work)
with bumblebee I could not run optirun or prium

PS: I used http://followthegeeks.com/a-noobs-guide-to-installing-nvidia-optimus-driver-in-ubuntu/ to solve black screen problem.

You can try downloading driver from xorg edgers ppa(https://launchpad.net/~xorg-edgers/+archive/ppa).

Add the ppa

sudo add-apt-repository ppa:xorg-edgers/ppa

upgrade your system

sudo apt-get update && sudo apt-get upgrade

Reinstall bumblebee.

If that doesn't solve your problem,

what is the error when you run optirun? include in your question.

A note : did you created this question yesterday? https://askubuntu.com/q/350922/35775 Don't create duplicate each day with different id that doesn't help here to get good answers.
