when I press Fn key + button for touchpad, I get popup as you can see on image, but touchpad is still working.
When I go to the Setting > Mouse & Touchpad, touchpad is disabled. I check to turn on, and uncheck again, and touchpad is disabled. Can you tell me how I can fix it? I want control tochpad with my default touchpad button with Fn key. My OS is Ubuntu Gnome 16.04 and laptop Asus N56VJ. Thanks.
