[ubuntu] Mousepad and keyboard not working on Dell XPS 15z

view story

http://ubuntuforums.org – Hi. I recently installed Ubuntu, but ran into the issue that my mousepad and keyboard are not responding when I run Ubuntu. I do have a USB mouse and that is working. Though, whenever I click on something (like the power button or anything at the top) it will automatically select what ever my mouse scrolls over. I don't even have to click. It also opens 20 or so windows if I click on something once. Please help, as I do want this OS. Thanks! (Hardware)
