My laptop keyboard and trackpad aren't working on my Dell XPS 15z.

I do have a USB mouse and that works, but, whenever I click on something, it opens about 20 windows of that. Or, if I click something on Google, it'll keep going to it about 20 times. Plus, if I press on the power button (on Ubuntu) with my mouse, it automatically selects what ever my mouse hovers over (even if I'm trying to go down and select "power off").

I've tried this on an external and internal hard drive. Same results each time.

Please help. I'm very interested in this OS.
