[SOLVED] [EDIT] Dell XPS 13/15 Problem (Brightness, Single Tap, Touch Scroll)

Well, I just bought a whole new XPS 13 and installed Ubuntu 12.04 Precise Pangolin 64 bit. But I was having some problems like the brightness didn’t worked as I expected, single tap that used to click made me a sad guy and Touchpad scroll weren’t working. But I love to know that there are people who love to solve problems that quick. I would like to thank to Kamal Mostafa who has been contributing us for the Drivers/Kernel patch for XPS versions.
