blindmankind Posted November 26, 2018 Share Posted November 26, 2018 Hello, I own a XMG P722 Pro Laptop which is similar to Clevo p370em. The graphic card is a SLI GTX 680M and the built-in display is a 3d laptop screen. My problem is that my laptop screen stays black when I boot without nv_disable=1 flag and with this flag, I have in System Info Nvidia Chip Model 7MB. When I connect an external monitor using DVI Port, this display works great but the laptop screen is still black. With HDMI port, the external screen is black too. I would like to have full acceleration QE/CI on my built-in display but what is the problem exactly ? I don't know. Sorry for my English I speak French Link to comment Share on other sites More sharing options...

styrian Posted November 28, 2018 Share Posted November 28, 2018 Hello! Are you using Lilu and WEG? Have fun. Link to comment Share on other sites More sharing options...
blindmankind Posted November 28, 2018 Author Share Posted November 28, 2018 Hello, Yes I put Lilu and WhatEverGreen kexts in /Library/Extensions, I used Kext Utility to repair permissions and rebuild kext cache, but no change. I verified that these two kexts are correctly loaded with the kextstat command by booting with nv_disable=1 flag. Link to comment Share on other sites More sharing options...
styrian Posted November 28, 2018 Share Posted November 28, 2018 Hello! You could try it in this way: https://www.insanelymac.com/forum/topic/323010-please-help-me-fix-brightness-control-nvidia-graphics-only-laptop/ Try at first only buiding the injector.kext with the script and install it to L/E. This tool is nice to install kexts. Give it a try by using it's advanced options: https://www.insanelymac.com/forum/files/file/397-easykext-pro-a-minimal-and-super-fast-kext-installer/ Also injecting with clover the id of the Nvda GT 650 m of MBP 9.1/10.1 as fake-id could help a bit. (Sorry don't know the mentioned ID) Have fun. Link to comment Share on other sites More sharing options...
blindmankind Posted November 28, 2018 Author Share Posted November 28, 2018 The AppleBacklight kexts don't solve the problem. Still black screen without nv_disable=1. I found the device-id of the GT 650M, it's 0x0fd5. So do I have to inject in the devices section of Clover the fake-id 0x0FD510DE ? Link to comment Share on other sites More sharing options...
blindmankind Posted December 1, 2018 Author Share Posted December 1, 2018 Isn't it a problem with 3D screens and Hackintoshes ? I have read in another forum that It could be that. Link to comment Share on other sites More sharing options...
styrian Posted December 1, 2018 Share Posted December 1, 2018 Hello! Normally not. The only thing is, that the Edid has dougle length 256 instead of 128. You should try to ad in CLover thekey Edid Data and leave it empty. More problems give SLI-GFX. Have fun. Link to comment Share on other sites More sharing options...
blindmankind Posted December 2, 2018 Author Share Posted December 2, 2018 Hello, Yes I have ever tried with and without EDID but still the same problem. I think the problem isn't related to EDID because with nv_disable=1, the bdmesg command shows me the EDID is the same as Windows. In fact, to precise the problem, without the nv_disable=1 flag, I have two issues: - With default macOS Nvidia driver, I have a black screen (the monitor seems to be turned off) after verbose boot. - With Nvidia web driver, I'm stuck at the end of verbose boot. I would like to try patching DSDT as explained in the link you sent to me but I don't find the area of my graphic card in the DSDT file. Link to comment Share on other sites More sharing options...
styrian Posted December 3, 2018 Share Posted December 3, 2018 Hello! Yoou can also add the properties in Clover/Devices/Properties. You have to get the adress of your NVDA with gfxutil. Have fun. Link to comment Share on other sites More sharing options...
blindmankind Posted December 31, 2018 Author Share Posted December 31, 2018 Hello, Sorry for the delay. I did some researches about EDID and I have seen in boot.log that Clover finds the correct 256 bytes EDID but in ioreg command there is no IODisplayEDID entry. So I have read this tutorial to override EDID in Displays/Overrides folder, I have modified the ProductID-717 file with the EDID from Clover boot log, and after reboot still the same problem, no IODisplayEDID entry in ioreg. I noticed too that there is no AppleBacklightDisplay entry in ioreg, but there is AppleDisplay entry. Can you help me a little ? Thanks. Link to comment Share on other sites More sharing options...
