I Have installed several video drivers from the software centre and I have installed the official driver from Nvidia.com and none of them show up in the additional drivers application. I did what this suggested but they still do not show Nvidia driver installed successfully, but not activated . The reason I am trying to use a different driver is because when I use the nouveau or the nvidia 331 driver I can't use my nvidia card, when I use the kernal and VDPAU 340 driver I get graphical glitches.

the intel card goes to the monitor port but the nvidia card is for rendering
