I recently bought a Dell XPS 15z. It came with Windows 7 Home Premium, but I really wanted to try out Ubuntu on it. I ran the Windows installer and was surprised how smooth the process was. Within 10 minutes, I had a dual boot setup with Ubuntu 11.10. It boots into Ubuntu just fine and everything seems to work. I've read a lot about problems with touchpad and wireless, but honestly, I've had none of those issues. The only thing that's really bothering me is the fan constantly runs fast. Under Windows, it rarely ever came on and when it did, it wasnt spinning that fast. What could be going on under Ubuntu that would cause this? I want to get that under control because I want to use Ubuntu as my primary OS and screw Windows.

Any help would be much appreciated!

Note: I've read that others have set acpi=false, but I have not made any changes to the default installation. Should I make that change?
