[Guide] Intel Framebuffer patching using WhateverGreen

[namnnumbr]

I'm having trouble with displayport connectivity. I'm running a Vega56 with a headless device ID. HDMI works fine. With DP, it boots fine and shows the bios on screen, but as soon as it tries to boot past Clover, I get a blank screen. I'm guessing this has to do with the framebuffer? However, the framebuffer patcher app only seems to work for identifying ports if you're using iGPU.

Any suggestions? Thanks!

Try AGDP patch aka "Black Screen Patch" in Clover Configurator Kexts to Patch section.

Still can't solve an issue with my UHD630 working with both DVI and HDMI outputs working simultaneously after boot. Only HDMI works after it. But when I turn sleep mode on and then wake it up, they're both working fine. What's the problem ?

I believe I have the same issue as you with HD630 graphics on a i5-7500 with a Gigabyte motherboard that only has HDMI, DVI, and VGA connector options, so hopefully you can provide your experiences so that I know if I should continue. My HDMI and DVI work separately, but together, HDMI will turn on, and be stuck in a "gIOScreenLockState 3" loop, and so I can't login. In addition, my DVI does not receive a signal when I have both plugged-in at boot when I reach the login screen. I only tried changing the BUS id of my HDMI port following the Intel FB Black Screen guide. Did you try changing the BUS IDs and Types for both your HDMI port and DVI port? And if you did, did you try all the combinations? I want to try all the combinations, but if it didn't work for you, I doubt it would work for me, so I might as well not go through all the trouble.

Thanks! the 'agdpmod=ignore' boot flag for whatevergreen fixed the issue!

what's the resolution you are trying to achieve? that can be the issue when trying to boot if not using correct boot flag, kext and or patches. I just went thru the same issue when trying to use 4k screen on my dell 7573. after some very sound advice from @jaymonkey, its working perfect. post PR files, I'm sure you'll find a resolution soon

Have you tried with just setting the correct ig-platform-id along WEG with no additional properties? In a lot of cases this is enough to get it working.
