I am having trouble with my precision touchpad and I think some developers who work in windows drivers might have some insight.
I'm more an application level developer though I've done some Windows driver development many moons ago.
I'm hopeful the problem could either be better understood using the right software tools and maybe even fixed with a custom driver or filter driver. The problem is seen on recent Dell XPS laptops. Others have this problem too but Dell says it's engineered this way.
The problem is that the bottom left 1cm x 1cm corner has a weird behavior. I want to click a button on the screen, so I touch the touchpad with a finger and move the pointer over the button. If I then STOP touching the mousepad and press the bottom 1cm x 1cm left corner of the touchpad, as if to do a left mouse button click, no mouse click actually occurs. Had I instead pressed the touchpad 1cm to the right it would have worked fine. Or had I kept the pointer finger on the touchpad, the click would have worked. There are of course other ways to click a button with a touchpad, including using a single finger to move and then double tap, I know. I am looking to have the problem fixed, not avoided.
Dell is saying "It was engineered to prevent a false touch or button click while typing on the keyboard." I get that concept but I'm not convinced someone thought to mask off such a tiny part of the touchpad that's farthest from your hands when typing. Not to mention I can rest my hands all over the touchpad and get no false palm touches, yet pointing and clicking work as expected everywhere other than this square.
It seems to me me the 1cm x 1cm corner registers x,y movements fine, and clicks like a button fine, in terms of feel and when the pointer finger is touching as described above.
So I'm looking for some guidance in my pursuit of a solution. Can anyone here envision a way to investigate this issue through software? Like how can I see what values are being produced from the touchpad before being processed by precision touchpad driver. Could you see any possibilities like using a filter driver to solve it? Could that work?
Thanks for anything
