djuby Posted October 3, 2021 Share Posted October 3, 2021 Hi all, I was able to install Big Sur with OpenCore and so far almost everything looks great, except for a few things that I need a little help with. I am ready to provide any additional info and files if needed. Here is the current state: - Graphics - OK - Screen brightens slider - OK - WiFi - OK - Bluetooth - OK - Audio - OK - Volume Up/Down keys - OK - Microphone - OK - Headphone jack - sound is distorted! - Keyboard - OK - External USB mouse on the USB-C port - OK - Build-in webcam - OK - Touchpad - WORKS AS A MOUSE. NO GESTURES! - Brightness Up/Down keys - NOT WORKING! - Sleep - OK - Wake Up - NOT WORKING! Any ideas how will be greatly appreciated. Thank you in advance.

Moderators Jake Lo Posted October 3, 2021 Moderators Share Posted October 3, 2021 Please post full system specs. What make and model of touchpad? Post your EFI folder plus IOReg file using IORegistryExplorer.app v2.1 only Link to comment Share on other sites More sharing options...
djuby Posted October 4, 2021 Author Share Posted October 4, 2021 Hi Jake Lo, Here are the complete system specs: 10th Gen 8-core Intel i7-10875H @2.3GHz Intel UHD Graphics for 10th gen CPUs, i.e. UHD 630 (dev id 0x9BC4) NVIDIA Geforce GTX 1650 Ti 4GB GDDR6 (unsupported) 15.6" Full HD+ 1920 x 1200 IPS WLED display 16GB DDR4-3200 RAM 512GB M.2 2280 Gen3 x4 NVMe SSD Widescreen HD (720p) webcam Killer AX1650 Wi-Fi 6 (11ax) a,b,g,n,ac + Bluetooth 5.0 card I was not able to find anything on the touchpad, except that is a HID device. I am attaching the IOReg file. EFI archive is bigger than the max allowed file size, so here is a link to it: https://ufile.io/5nvdatjv IOReg.zip ... and here is dump of IO devices from Ubuntu devices.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 4, 2021 Administrators Share Posted October 4, 2021 Erm... According to the Dell support web site, this XPS 15 9500 laptop is fitted with an ELAN touchpad: https://www.dell.com/support/home/en-us/product-support/product/xps-15-9500-laptop/drivers Link to comment Share on other sites More sharing options...
djuby Posted October 4, 2021 Author Share Posted October 4, 2021 When I use the service tag (hs32793) I don't see this driver. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 4, 2021 Administrators Share Posted October 4, 2021 Hmm, I do... Anyway, you know what you have now. Link to comment Share on other sites More sharing options...
djuby Posted October 4, 2021 Author Share Posted October 4, 2021 OK. Great. Now, which driver should I use for the Touchpad? Do I need DSDT patching? This is wired. When I use the service tag I get this: ELAN is not the one in this PC. Did you check the IO device dump I posted earlier? Maybe that will make it clear which one is it?

djuby Posted October 5, 2021 Author Share Posted October 5, 2021 Latest update. Tried VoodooI2C kext with ELAN and HID satellites, but with no luck. I guess some patching is needed to enable the I2C controller. How is patching done in OpenCore? Best regards. Link to comment Share on other sites More sharing options...

djuby Posted October 5, 2021 Author Share Posted October 5, 2021 One question. What is better to use with OpenCore - DSDT or SSDTs? Link to comment Share on other sites More sharing options...
