Trying Ubuntu HardyHeron on my laptop. Almost everything is working except for video and wireless. I think I have found the answer for the wireless, but the video is driving me crazy. It shows up under hardware drivers in the system menu, but it shows, enabled but not in use.

I have an HP dv6636nr with a Nvidia 7150go card...?

Any ideas oh Ubuntu/linux experts?
(PS, I am a complete n00b to this stuff, so KISS would be appreciated! )
