Administrators Hervé Posted May 20, 2021 Administrators Share Posted May 20, 2021 Anything is possible, but that does not really help, does it? Did you check the info of the TrackPad driver for Latitude 5510 in the support section of Dell's web site? Edit: Ok, here goes... PCI id 0488:121f -> It's a Synaptics Touchpad.

ONRA Posted May 20, 2021 Share Posted May 20, 2021 @ Hervé Thanxalot for the info. So I need to uninstall the VoodooI2C kexts ? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 20, 2021 Administrators Share Posted May 20, 2021 No, I2C is not a brand of Touchpads... https://en.wikipedia.org/wiki/I²C Look up Synaptics I2C kexts... if that exist. Link to comment Share on other sites More sharing options...
ONRA Posted May 20, 2021 Share Posted May 20, 2021 @Hervé Yes I found a VoodooI2CSynaptics. Do I need to uninstall some kexts ? Or just add that VoodooI2CSynaptics ? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 20, 2021 Administrators Share Posted May 20, 2021 Look up the documentation that goes with those Synaptics I2C kexts; usually there are PlugIns for the various brands and you'd need to remove Alps Plugins if you used those for instance. Can't say more, haven't done much experimentation since the Latitude 5490 that I no longer have and I never spent much time on it. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 20, 2021 Moderators Share Posted May 20, 2021 @ONRA On my Precision 5510, it also has a Synaptics I2C touchpad and using VoodooI2C + VoodooI2CHID worked just fine. You could try removing VoodooI2CHID and replace it with VoodooI2CSynaptics and see how it goes. Link to comment Share on other sites More sharing options...
ONRA Posted May 21, 2021 Share Posted May 21, 2021 Hi you all, Finally, I have succeeded in an installation that is not yet 100% but almost. Shout out to @Jake Lo & @Hervé for your precious advices & technical helps. The only thing that is still not working is the trackpad which is quite basic. As soon as I touch the trackpad, the pointer goes to the left. I have to use a second finger to select something and a second Tap to open something. I tried various kexts (VoodooI2CHID & VoodooI2CSynaptics) but still no real working trackpad. Maybe there are still errors in my config.plist. I think I'm about at the same point as @denkteich is with his configuration. I'll keep looking on my side. If you ever think of something while checking my files, I'm interested HackBook-Latitude-5510.ioreg config.plist.zip Link to comment Share on other sites More sharing options...
ONRA Posted May 21, 2021 Share Posted May 21, 2021 I found this on github: https://github.com/VoodooSMBus/VoodooRMI Do you think it's related ? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 22, 2021 Moderators Share Posted May 22, 2021 You could try it. I have it on my Lenovo with SMBus touchpad, but that supports I2C as well. Link to comment Share on other sites More sharing options...
ONRA Posted May 22, 2021 Share Posted May 22, 2021 Is there a specific order to install VoodooSMBus & VoodooRMI ? Link to comment Share on other sites More sharing options...
