drivers - Can't use Nvidia GeForce 310m in Ubuntu 13.04

Okay so before anybody marks this as a possible duplicate or something along those lines let me say what ive worked on; I have used Bumblebee,Manually installed the drivers myself,tried a bunch of old drivers and new ones in hopes of something happening,re-installed drivers and bumblebee and done a re-installation of the OS and nothing...

Im dualbooting Ubuntu 13.04 next to Windows 7 (both are 64-bit) and the problem is that i cant seem to get my GPU running and i found that Ubuntu cant acces the gpu for some reason (this showed up while working with bumblebee in a terminal)...i have Intel HD Graphics (built in) and an Nvidia Geforce 310m (512mb)

These are my specs;

CPU; Intel Core i5
Ram; 4Gb (3.7 to be exact)
HDD; 500gb (divided equaly in half for both Operating Systems)
GPU; Nvidia Geforce 310m 512mb (as mentioned)
Computer/Laptop; Toshiba Satellite E205

:) Help is apretiated

i have the Samsung q330 and i have the same issue, i can resolved it with this.

Open synaptic and remove all nvidia drivers and nouveaun, like so:

sudo apt-get purge nvidia * nouvea* or sudo apt-get clean nvidia* nouvea*

Open terminal and install:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install linux-headers-generic nvidia-319
sudo apt-get install bumblebee virtualgl linux-headers-generic
sudo apt-get install mesa-utils
sudo reboot

And you can test with this command:

optirun glxgears -info

If all works out you can see something like this:

• GL_RENDERER = GeForce 310M/PCIe/SSE2


• GL_VERSION = 3.3.0 NVIDIA 325.15


• GL_VENDOR = NVIDIA Corporation

its run some 3D graphics and say you fps.
You can use too optimusrun glxspheres, and glxspeheres to test mxpixel/sec
Good luck
