mouse and keyboard freezez on DELL XPS 15z laptop

Asked by reza shirali

Hello all,
I have tried the latest ubuntu 12.01 LTS and 12.1 on DELL XPS 15z laptop wit Windows 7 preminum, but when I restart ubuntu the mouse and keyboard are frozen and not responsive. The only way I can use the ubuntu is by using external usb mosue and keyboard. Is there a configuration file i need to change? Please be specific and detail, since I am new with linux. I also, tried version 10.04. In this version the keyboard and mouse work, but the wirless connection does not. I have added the wirless MAC address shown in dos mode cmd (ipconfig /all) in VPN configurator, and still can detect wireless.
Thanks,
R
