I just installed Ubuntu 12.04 on my Zotac box which has an Intel Atom D525 with Nvidia ION 2. I updated the software and after going to the additional drivers I installed the nvidia_current and nvidia_current_updates. After a reboot I still see a message that says "This driver is activated but not currently in use". When streaming online the video is very choppy and I see that the CPU usage is close to 70%. Also, in the System Settings-> Details the Graphics tab is shown as unknown. Any idea how i can get the driver to be used? Thanks for your help with this!
