I am looking for the drivers for Integrated Display on Lenovo 420s Core i7. This computer has the nvidia optimus option. Can anyone point me in the right direction?

Ubuntu version: 10.04 LTS

Thanks,

Did you check the window Additional Drivers? Maybe your system has detected an appropriate driverm but it hasn't installed it.

I have already checked that. Nothing shows up in that list.
