ELAN, FocalTech and Synaptics (Smart Touchpad) Driver

Hello, I have a HP DM4 2075BR with the touchpad ALPS, I have tested all kinds of kext and they all do not work multitouch, the strange thing is that any one that I place works, but without multitouch !! post I tested all 2: Smatchtouch, EllanTouchpad !! the touchpad always work, but never with multitouch!

Someone can help-me?

I have sierra!

I have the same issue HP Elitebook 810 g2 El Cap 10.11.6 Alps touchpad. I've tried every kext known to man for Alps and nothing except simple mouse function. This one has the best function and the trackpad pref pane is working, except no multitouch function. I suspect we are getting enhanced mouse function. I'm willing to do whatever it takes to get the ALPs driver supporter here. The latest version works great even the keyboard functions are right, no sound issues either.  Is there a way I could add my id into a info.plit inside the kext to allow me to test ? Truth is I would be happy with just 2 finger scroll.  There is actually quite of few Dell models also with Alps as well.  

 

Any help in this matter would be much appreciated.

 

Thanks

Also, brightness keys can be mapped to F14/F15 if your PS2 kexts allow for customization. For example, with my version of VoodooPS2Controller.kext, you can customize the mapping with ACPI. The following small SSDT can be used to map the Dell PS2 codes to F14/F15 instead of the codes normally used for brightness:

 

Code (Text):
// Custom ADB codes to change Dell brightness keys to F14/F15

// some SSDTs use a different path than _SB.PCI0.LPCB.PS2K, so adjust accordingly

DefinitionBlock ("", "SSDT", 2, "hack", "ps2k", 0)

{

    External(\_SB.PCI0.LPCB.PS2K, DeviceObj)

    Scope (\_SB.PCI0.LPCB.PS2K)

    {

        Name(RMCF, Package()

        {

            "Keyboard", Package()

            {

                "Custom ADB Map", Package()

                {

                    Package(){},

                    "e005=6b",

                    "e006=71",

                },

            },

        })

    }

}

//EOF

Is this possible with this kext? i really don't want to use Fn for brightness, everything else already works on my keyboard.
