If there are no more sensors detected (just the virtual), it's a bad sign :-( Sorry, I'm out of ideas. Laptops are very customized/closed devices, I'm afraid they come ready for Windows (you'll see there are lots of tools for controlling fan speed and temperature measuring _inside_ win). Also, manufacturer's tools to handle this are designed for Windows. I know there are some linux packages for specific laptops (Toshiba, HP...) that allow to control/customize the function keys and do other fancy things, maybe you can find something similar for Acer :-? A BIOS update can (sometimes) help, but don't do it unless you know for sure what are you doing :-) Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
