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

You can try downloading driver from xorg edgers 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? Nvidia GTX 765m Optimus tech on ubuntu 12.04 Don't create duplicate each day with different id that doesn't help here to get good answers.

optirun firefox : [ 745.002097] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected. [ 745.002131] [ERROR]Aborting because fallback start is disabled. I tried to delete the question because server didnt let me log in for some I had to create duplicate question sorry. – Rui Sep 29 '13 at 9:57
I"ve just checked and it is no longer unclaimed. However bumblebee stays off and overview doesnt show graphics at all... – Rui Sep 29 '13 at 10:14

After many trials I finally found the problem related with the Kernel. For me this makes the VGA work, you can give it a try. Jump over to a terminal with Ctrl-Alt-F1 :

sudo apt-get install linux-source

sudo apt-get install linux-headers-3.5.0-18-generic

sudo add-apt-repository ppa:bumblebee/stable

sudo apt-get update

sudo apt-get install bumblebee bumblebee-nvidia

sudo reboot

good luck.

Following Web-E answer, after a reboot

   sudo apt-get update 

stopped working. I managed to get it going by following the solution here, in other words by using

   cd /etc/apt/sources.list.d/
   sudo rm xorg-edgers-ppa-trusty.list
   sudo reboot
