Ok, and I start..
I own a Dell Vostro 3450 from Dell last year. This Laptop has a 14 inch screen, 4 GB of RAM and a Intel core i5-2430M. This processor has an integrated GPU Intel HD Graphics 3000. The lapto also have an AMD GPU (6630).
I tried first Ubuntu 11.10 and when I tried to install the alternative controllers, after the restart the screen goes black.
Now I'm using Ubuntu 12.04, I just try to install the propietary drivers and after reboot the system works, but I got Unity 2d. When I tried to use an specific xorg file to use the ATI GPU after the reboot I got a message that my X server configuration was bad (the tutorial to fix problems), so I uninstalled the drivers, reboot and got again Unity 3D working under the Intel GPU.
This is the info of my laptop:
