Dell XPS 15z Multi-touch Odd Behaviour

view story

http://askubuntu.com – I have a Dell XPS 15z with 12.04 installed. Once in a while, when I'm using multi-touch scrolling (two-fingers to scroll down), the computer logs out. It's as if I clicked the log out button, but there's no pop up asking me if I'm sure. Also, my work is not saved and all open programs are closed. How do I fix this? It's really annoying! (HowTos)
