<< Solved >> Trackpad stop working after sleep

[KVyDavid]

I'm running macOS Monterey on HP EliteBook 820 G2 with PS2 trackpad. The trackpad is very responsive and multitouch gestures working properly. But when I wake my laptop from sleep, the trackpad stop functioning until I restart the machine.

How do I fix that?



Kexts I'm using:

• VoodooPS2controller
• VoodooRMI
• VoodooSMBus

If I remove the last two kexts, touchpad still works after sleep but it's very sluggish.

Solved by myself: I don't know why I just read the readme.md file of voodoosmbus.kext and it says I have to disable VoodooPS2mouse.kext plugin in VoodooPS2Controller.kext. I disable it and now everything works!
