jonny Posted July 29, 2018 Share Posted July 29, 2018 @giang_asl_8, you can fix the graphics switching problem by doing the change via UEFI instead of navigating the Dell BIOS. 1 Link to comment Share on other sites More sharing options...
ericarthurc Posted August 20, 2018 Share Posted August 20, 2018 Can anyone help me with this?? So my 7510 has an AMD w5170m (R9 375x) and the Intel HD 530. Here is my issue: iGPU only: interal display works correctly, external video outputs (HDMI, miniDP) don't work at all; kernel panic on the miniDP dGPU only: using Ebi framebuffer and ATI inject (Verde kext too for power gates) the system boots but I am getting low color depth on my internal display, there is color banding, gradients look bad. But the HDMI and miniDP work and there is no color banding on the external displays, only my laptop display and I can't fix it... I tried EDID injection... Won't fix it. I tried injecting different framebuffers.. modifiying framebuffers.. (this was all done without whatevergreen.kext btw) With whatevergreen it's the same issue though, low color depth and color banding... iGPU + dGPU: Intel controls the laptop display and it works fine, good color depth. External video outputs only show black screens, but the Mac system recognizes they are there in system prefs. Just black. Ideally, I would just like to pick one GPU and disable the other, but have fully functionallity. If I can fix the video ouputs on the iGPU, or fix the color banding on the dGPU. Any help would be appreciated. Link to comment Share on other sites More sharing options...
Kernel_Pan1c Posted August 20, 2018 Share Posted August 20, 2018 So to continue this dual graphics discussion… For a while I understood that with Optimus enabled, the m2000m and iGPU both appearing in system profiler was relatively meaningless because apps I was running couldn't utilize it (adobe photoshop and illustrator showed only iGPU). However, I'm now testing a prerelease version of adobe illustrator that adds "eGPU" support and the m2000m now shows up in performance settings in illustrator. In addition, geekbench does appear to allow access to testing both cards. What I'm now wondering is if there could be a way to "trick" the OS into thinking the m2000m is an eGPU to use globally or maybe it already does now that apple has added support, but I don't know what applications I could further test this with. Just, to me, some interesting observations. Obviously still a power drain, but has it's advantages and could be switched by simple restart. As a side note, I don't use Intelgraphicsfixup or Nvidia fixup as they both disable one or another external port. Link to comment Share on other sites More sharing options...
giang_asl_8 Posted August 24, 2018 Share Posted August 24, 2018 @jonnyThanks a ton. This is the solution I have been finding for almost half a year!!! My hackintosh can now become more helpful in daily usage, that it couldn't before, due to the annoying steps when boot/reboot. Chose the 1st menu entry to disable discrete Nvida card, and now both the black screen after waking from sleep, and card switching disabled issue have gone. But I have 2 questions: 1. I copied your EFI folder to my existing hackintosh USB's to use the script. That causes my hackintosh rescue USB stop working, certainly. Is there a way to have both your booting script and clover booting on the same USB, that will be convenient to only maintain a single USB. 2. Because I both use may laptop as a Windows and Hackintosh, and it will be preferred to have both graphics card on Windows, so is there a way to acquire that without booting to choose the 2nd option (restore BIOS setting) before booting to Windows. Thanks in advance. Link to comment Share on other sites More sharing options...

giang_asl_8 Posted August 26, 2018 Share Posted August 26, 2018 Just to be sure before making everything a mess, I have a question. What does install_to_ESP actually mean? Will it not override or corrupt existing Windows and Clover boot item on my hard drive? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted August 28, 2018 Administrators Share Posted August 28, 2018 back up your EFI folder just in case.worst case you drop it back in. Link to comment Share on other sites More sharing options...

Need to choose option 2 to re-enable the dGPU if need it. If do the install_to_ESP then it's very easy to run before booting Windows as a F12 bootitem. May I have one more question. I successfully disabled the discrete Nvidia card using your guide, but I notice the script include setting DVMT buffer to 96MB, but I still cannot boot without the Clover's DVMT buffer patch (a panic related to AppleIntelSKLGraphicsFramebuffer). As my understanding, this script sets buffer size to 96MB and the DVMT patch should be unneccessary. Please correct me if I'm missing something. P/S: The issue above is on a Mojave setup.
