I just installed a fresh Ubuntu 12.10 64-Bit Desktop on my Lenovo W520. It looks like there are a lot of challenges around making it work with out of the box
Nouveau drivers or propriety
Nvidia drivers or
Intel GPU. I looked at couple of notes on how to make it work with
Optimus Nvidia. None of them seems to work for 12.10. Anybody has a solid answer on this? It seems like a lot of people are suffering from this.
Here is my
xrandr output. Let me know if you need any additional information.
