I'm currently running a dual screen setup where one of the screens is running off my old dGPU and the other one is running off the iGPU. I was able to swap the old dGPU by just adding agdpmod=pikera, however, I'm trying to stop using the iGPU for a display output but changing initial display output to PCI results in a black screen.
Things I tried that didn't work:
- Updating WhateverGreen
- Removing WhateverGreen
- https://github.com/acidanthera/bugtracker/issues/901
- MacPro7,1 SMBIOS
Specs:
- i5-9600k
- ASUS DUAL-RX5500XT-O8G-EVO
- Gigabyte H370M DS3H
Configuration: https://github.com/dimitarnestorov/Gigabyte-H370M-DS3H-i5-9600K-R9-270X-UHD-630 (it doesn't have the agdpmod=pikera boot flag yet, and also I'm changing the ig-platform-id to 0300913E, also I updated to 10.15.5)
Any ideas and suggestions are appreciated!
