Hello. I have a problem with trackpad. Movement is very unpredictable. I have Laptop Samsung R730. I install latest Clover and El Capitane OS. Almost everything is working. Trackpad is working well with VoodooPS2. But I try SmartTrackpad kext for keyboard extension and keyboard Numpad keys is working like I expect. But Touchpad - some time cursor move itself after sliding. Some time its position jumping. I try to change some values like Acceleration and another but no result. I turn off many boolean parameters like 2 3 4 fingers and so. Can I use for example just keyboard features? Or turn off any features for Trackpad ? Thanks.... Sorry for bad english.
