Trackpad Elan meta issue

[Andrey1970AppleLife]

Currently broken on some machines

• Trackpoint on some Lenovo machines (Direction problem with Lenovo Trackpoint + Cursor speed inside texts #1226)
• No movement on some V4 machines like AsusPro P2540UA (voodoops2elan is loaded on Elan v4 but no move or click #1220)
• Failing to enable touchpad after wake (Elan touchpad does not work after sleep. #1307)

——————————

The trackpad Elan v3 works only as a mouse.
Doubleclick works.
Trackpad keys work.
Gestures don't work.
Trackpad preferens panel don't work.

What logs are required from me?

Seems like VoodooPS2Elan (and therefore VoodooInput) is not loading. Do you see VoodooPS2Elan in IOReg?

Wow. After the second bootloading the trackpad works now. VoodooInput is loading.

But there is a problems.
The pointer moves a jump in the screen edge.
And the pointer transfers for the edge of the screen and appears on the other side of the screen.
I will make video soon.

Use "Show Live View" in BetterTouchTool and make a video to show both cursor movement and reported finger positions, like this: https://www.icloud.com/iclouddrive/0GMkGsJJOEoW26feE-TTtZCcA#synaptics

I think FingerMgmt is enough. No need to use BetterTouchTool

@hieplpvip Live View in BTT works even after the expiration of trial license. But thanks, I’ll look on FingerMgmt too.

Hi Good day.

I also have issues with the latest release as my Elan trackpad doesn't work anymore. Previously, my trackpad only worked as a mouse without the trackpad preference showing up in System Preferences. After the v2.1.7 release, the preference pane shows up (I appreciate that) but my trackpad doesn't move, click or do anything anymore. Voodoo input and VoodooPS2Elan loads as I've seen in IOReg.

I have an Asus P2540UA Laptop. Tell me if you need more information.
Any help would be appreciated. Thank you.

Are you sure your touchpad is using PS2 Interface?? Most kabylake laptop of asus are using I2C Touchpad

I think mine uses the PS/2 interface as I saw on windows device manager (Trackpad BIOS Device Name: _SB.PCI0.LPCB.PS2M). Is there anyway to check if my trackpad uses the both interfaces?
I also confirmed it is Elan v4. Would I need to create a new issue thread for this too?

Try to disable ForceTouchMode. Either with control panel if available, or in Info.plist of VoodooPS2Elan.
