Enable I2C Trackpad (VoodooI2C) - Not a Guide... not really

[onemanosx]

[ref]ameen[/ref], try a different count in the range of 40s. Reboot and check in DSDT XCRS location.

I can guide you but not count for you.

sorry for late replying

I couldn't get to work my trackpad in the range of 40

did you count with comment or without comment ?

when I put tableSignature 44534454 or skip 39 count 1 then stuck on this screen

https://i.imgur.com/o0eNeDB.jpg' alt='IMGUR>'>. I think my skip count is wrong

when I go to pre-edit system dsdt in _CRS location nothing change

[ref]ameen[/ref], Perhaps I did not make it clear enough.

1. TableSignature 44534454 is required.

2. You are unable to boot with your count 39 because the count is wrong and instead disables other _CRS method.

3. The idea is to be able to boot with effective _CRS to XCRS by injecting other random count and see in your pre-edited DSDT where that XCRS method is patched. From there, you are able to make an educated count towards TPD0._CRS

In your latest troubleshooting archive, clearly your XCRS patch is a failed attempt. Probably, you did not use the correct TableSignature I had mentioned in point 1.

Experimental: You can try using this SSDT

 

DefinitionBlock ("", "SSDT", 2, "1MOSX", "SDM0", 0x00000001)
{
   External (SDM0, IntObj)

   Scope (_SB)
   {
       Method (_INI, 0, NotSerialized)  // _INI: Initialize
       {
           If (_OSI ("Darwin"))
           {
               SDM0 = Zero;
           }
       }
   }
}

 

Make sure you disable all track pad renames

Hi I have a Lenovo ideated 330 with an elan touchpad, now the trackpad only works for moving the mouse around nothing else so can you help me with this please?

[onemanosx]

[ref]Titanium[/ref], Have you checked in BIOS options for advanced mode for track pad? I don't see anything peculiar in logs.

[Titanium]

On my BIOS I dont have any option referring to the trackpad [ref]onemanosx[/ref].

[onemanosx]

[ref]Titanium[/ref], You can try VoodooI2CELAN kext. Make sure you remove VoodooI2CHID kext.

hi [ref]onemanosx[/ref], thanks for your help on enabling my i2c trackpad before.

now my trackpad is working well, and my touchscreen is working too (as big trackpad ) but now i want to disable my touchscreen since the gesture is not as good as windows's touchscreen and its only drain my battery. so, what should i do to disable the touchscreen?

LOL!

You can easily disable the touchscreen by renaming _CRS to XCRS for TPL1 (assuming TPL1 is your touchscreen). You can do this either in DSDT or Clover hotpatch.

[aryaone]

thanks for your advice, will try it ASAP and hope this will improve my battery usage time

Meu trouchpad se move,

O botão esquerdo do trackpad funciona normalmente,

o botão direito do trackpad tá com a mesma função do esquerdo (Só seleciona e abre, a função certa para esse botão deveria ser: aparecer o menu)

Mas meu touchpad não está com a função tap ativa, não funciona rolagem de página, nem zoom.

Nas configurações do trackpad não aparece nada detectado, nem nas configurações de mouse.

Que treta devo resolver pra ela funfar?

1. You did not install I2C kexts

2. You did not use a patched DSDT

3. You did not implement kext to patch for I2C in config.plist.

Please read post 1 again.

Is your battery status working? Track pad preference will not show if battery status is not working.

I installed Catalina and battery is working but the trackpad isn't detected in the settings but it works as a mouse so no gestures are working can you help me to fix it

[ref]ahmedgamal09[/ref], Your DSDT is not patched to use interrupt mode. Find TPAD device in DSDT and change _CRS method to

Return (ConcatenateResTemplate (SBFB, SBFG))

as per the guide.

Make sure to read post 1, too.

Its also worth a try to static patch Windows emulation to recent version rather than Windows 10.

You only need VoodooI2C and VoodooI2CSynaptics kexts. Remove all other voodooI2C kexts.

Your _CRS patching is wrong. Change it back to native and try again. Please read post 1.

When I remove VoodooI2CHID.kext, my trackpad don't move

you need to add your trackpad device name in synaptic kext. And you also need to patch your _Crs return correctly

You have had multiple OSI patches but did not patch the latest.

Only latest OSI emulation.
