f00b4r0 Posted December 21, 2020 Share Posted December 21, 2020 Hi, This is related to I am having the exact same problem, running 10.15.7 on my Hack #1. Since I upgraded to Catalina, every now and then my 4k display connected to the dGPU will fail to wakeup. If I edit my OC config.plist to add the suggested CFG,CFG_USE_AGDC, I boot to a black screen, that eventually turns into something like this: The pointer (visible in the top left corner) is working, but that's otherwise completely unusable. That's with OC 0.6.4 Is there anything else that can be tried to address this issue? Thanks Quote Link to comment Share on other sites More sharing options...
f00b4r0 Posted December 22, 2020 Author Share Posted December 22, 2020 Which one(s) are you referring to? The only one I'm aware of that would do something like that is igfxonln, but that's for iGPU as I understand it. Thanks Quote Link to comment Share on other sites More sharing options...
