BIOS function to disable touchpad not working

[Hadmut Danisch]

Hi,

I have an ASUS notebook with - like virtually all notebooks - a touchpad in front, which generates bogus mouse input when using the keyboard due to hand movements. Therefore the notebook has - like most notebooks - a special function (press Fn + blue symbols on keys) to disable the touchpad when using an external mouse.

This worked well with 14.04, but doesn't work with 15.10 and 16.04.

Since the mousepad is rather sensible, it makes using the notebook under Ubuntu rather difficult. Cursor quite often jumpst to arbitrary location while typing text.

regards
