Hi everyone!

 

I hope that everyone is safe and ready for a more sane New Year!

 

I'm setting up an HP 15-AB, i5-5200U with OpenCore and I have mostly gotten everything working, including my DW1820A wifi, (Thanks to Hervé's work). However, I seem to be having a problem getting the Synaptics Touchpad working. I've tried a couple of VoodooPS/2 kext's, but I get nothing. Here my hardware:

Spoiler

 

cat /proc/bus/input/devices

I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input6
U: Uniq=
H: Handlers=mouse1 event6
B: PROP=5
B: EV=b
B: KEY=e520 10000 0 0 0 0
B: ABS=660800011000003

cat /proc/bus/input/devices |grep -i name

N: Name="SynPS/2 Synaptics TouchPad"

dmesg |grep input

[    2.086391] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input6

 

 

I've tried the following kexts:

 

VoodooPS2Controller.kext

VoodooRMI.kext

VoodooSMBus.kext

 

which should work for this trackpad. I'm including my EFI in case the error is in the way I setup my config.plist

 

Any suggestions?

 

Thanks and have a great year everyone!

HP devices, if you have CSM or fast boot enabled, like to put the Trackpad in a bad state and not allow it to work over SMBus. This breaks graphics for a lot of HP laptops though, and I never thought to check CSM - was quite the head scratcher to be honest :lol:

 

Recently put in a mechanism to reset the trackpad into VoodooPS2/VoodooRMI, though the next release with this code will be the first Monday of January (When Acidanthera does their releases). I'll attach a copy of these kexts w/ the modifications - they're just built off of the master branch in VoodooPS2 and VoodooRMI if you'd like to do it yourself though.
With these versions, make sure VoodooPS2Trackpad is enabled

Hi @1Revenger1. I went through my BIOS, (which is total {censored} compared to a Dell BIOS), and I didn't find any fastboot options:

Do you have any links where I can read up on this and learn how to do what you describe, (rather than just copying someone else work)?

Is this something I do with the actual kext or is it in the config.plist?

 

Thanks for your help!

Hmm, digging through my config.plist, I'm finding a lot of entries for voodoo:

Do I have to many voodoo references in my config.plist?

OK, I managed to solve this problem by going through my config.plist and removing all entries for voodoo and then adding them one at a time. It turns out that the VoodooRMI.kext was causing the problem... not sure why, but I will keep on digging to sort things out properly. "Just "working" isn't good enough for me, I want to know the reasons things didn't work like they are supposed to.
