XPS 9570 i7 4k touch blackout after big sur upgrade from catalina #48

Hello thanks for your time and work, much appreciated. I have a problem. I install Catalina using the repo, screen works fine and is not blackout. After that when I try to install big sure beta 9 with the installer on USB, when the laptop reboot to finish the installation I get the apple background and looks like it finishes but after that I can't see anything on the screen, it goes black. I'm using XPS 9570 i7 4k 1tb Toshiba m.2 touch.

P.S. I have read through the issues tab on you repo and see similar issues but when I make changes the laptop still blackout.

Have you added the EDID into your config?

I did last week, but I scrapped that. I added pci location from using hackintool. HDMI works with external monitor.

Fyobl commented 3 years ago

Have you tried to use verbose mode with the debug versions of opencore? Maybe something in the logs will help

jaromeyer commented 3 years ago

then you probably did the EDID patch wrong

gknyce commented 3 years ago

Using hackintool could I past my EDID here for you to patch it for me? The info from the tool says that the frame buffer matches with intel 655 and not the 630 iGPU.

@gknyce

send me the output of ioreg -lw0 | grep -i "IODisplayEDID"and ill give you a patched EDID that you can add here: Devices>Properties>PciRoot(0x0)/Pci(0x2,0x0)>AAPL00,override-no-connect

@gknyce

Im sure you just add 00ffffffffffff004d108d1400000000051c0104a52213780e522daa5335bc250c5155000000010101010101010101010101010101014dd000a0f0703e803020350058c210000018000000000000000000000000000000000000000000fe00464e564452804c513135364431000000000002410328011200000b010a20200009

reset NVRAM and try again

@jaromeyer is that correct?

gknyce commented 3 years ago

Thanks but it does not work. Should the upgrade to Big Sur from Catalina happen on the internal drive or external USB, meaning to copy it to the internal name or just from the usb.

Fyobl commented 3 years ago

I just used the system update tool... but I got the black screen issue but with the EDID patch It worked like a charm

jaromeyer commented 3 years ago

@gknyce Heres your patched EDID: 00ffffffffffff004d108d1400000000051c0104a52213780e522daa5335bc250c515500000001010101010101010101010101010101a6a600a0f0703e803020350058c210000018000000000000000000000000000000000000000000fe00464e564452804c513135364431000000000002410328011200000b010a202000da @Fyobl you have to patch it before injecting, otherwise it will do absolutely nothing because it will replace the original EDID with itself.

jaromeyer commented 3 years ago

also i did a normal OTA from Catalina to Big Sur.

Fyobl commented 3 years ago

@jaromeyer How do i patch it ?

jaromeyer commented 3 years ago

edit 4 bytes and then recalculate the checksum. heres a great python script

gknyce commented 3 years ago

Thanks @jaromeyer @Fyobl for your help, I finally got it working. I have EFI to boot Big Sur, I added vit9696 boot arg and also the patches EDID.

After patchid EDID, is it running at 48 Hz or 60 Hz?

gknyce commented 3 years ago

Resolution is 4k, but then UI looks like 1080 @48hz

jaromeyer commented 3 years ago

Pretty sure its 48Hz only for now

imraan-go commented 3 years ago

Pretty sure its 48Hz only for now

How does it feel with 48Hz? is it usable? i think i'll feel dizzy running 48hz for a long time 🤕
