I am new to Linux and do not have much experience. I am going to do the best I can to explain my issue so please be patient with me. I am running Ubuntu 16.04 with a Logitech K830 wireless kybd. This is not a synaptics touchpad and when I use two finger scroll, stop and lift my fingers from the pad, it will then scroll several pages more. It's almost as if I was using a mouse wheel what has an off center oval wheel that continues to rotates a few pages. It does not always do it but most times it does. Also the touch sensitivity is extreme and hardware mouse and touchpad settings have no option o change sensitivity settings. Most of the time I don't even know that my finger has touched the track pad and I am jumping all over the place. This is very frustrating and need help. Same thing happens with Synaptic track pads also but I like the K830 because the track pad is more like the Mac in that it is smooth textured.
