Refined ALPS TouchPad driver in Kernel Extensions Posted November 6, 2018 On 2/13/2017 at 7:50 PM, Bronxteck said: just checked Herve. yeah no plugins just container. hence no trackpad or keyboard kext inside. forgot to check lol. recompiled from source on post 582 VoodooPS2Controller.kext.zip This kext works on my E5250 I can see touchpad gestures in settings but it has some problems "Sometimes jumps when scolling with two fingers" "Only 3 and 4 finger swipe up (other directions are not working)gestures works" "Pinch in-out gestures not working "And cursor jumps sometimes"
