I installed Ubuntu 12.10 on the Lenovo S206 of my brother and already spent hours on trying to get the graphic driver to work.
No matter which solution I used, in the end Unity crashes, after the login I can see files on the desktop and also open folders and so on, but there is neither a window manager nor any sign of Unity (no panel on the top, no sidebar).
I used this instruction to install the driver and I also tried generating distribution-specific packages.
My Brother wants to go to France in two days, I hope you can help me out.
