I am trying to fix this issue for weeks now.
My laptop is g551j - the gaming notebook.
I wanted to set it up so that asus smart gesture disables the mousepad when mouse is detected, in the options I have that checked, but it doesn't disable mousepad at all, and when I try to manually disable my mousepad using fn+g9, nothing happens either.
I've tried updating all drivers, Ive updated the Smart Gesture from asus support itself, and I also uninstalled the ROG Mouse gaming program too thinking it may be causing the issue since I don't use the asus mouse and I use my own, so I removed that program.
I also reinstalled the drivers from support asus site
