RX 6800 (Sleep/Display)

[rossi]

What does this mean?


Provide the GPU model and if possible, attach a real picture of the card. There are some cards which fails to realize if a display is connected/disconnected and a reboot is needed for the affect.

Some questions at this point:
- Are you using the cables supplied by the monitor/TV?
- Did you purchase the new GPU or is it some kind of refurbished/used/mined?
- What macOS version are you running? Include the build number.


Well, it could be either your GPU or the firmware itself. Somehow, your BIOS Settings might be affecting this. Provide the complete BIOS walkthrough.

It means I tried a display port (with DP to HDMI adapter).
GPU Model as in my profile. Bought on ebay. Tried all sorts of cables. Don't know if I even possess the original cables any more. Card looks like this:


MacOS build is 14.5 (23F79)

Will check how to create BIOS walkthrough later. In the end this is sort of getting out of hand. The effort spent troubleshooting this stands in no relation to the achieved improvement. Especially since I have a feasible workaround.

And please don't get me wrong. I highly appreciate your help. You are a very nice person who is kindly willing to help others. But this is a community - so maybe someone else jumps on this train. Or the problem is just too rare to bother at all.

Is the system root patched then?

Its upto members who either have interest in helping you or not. xD

The system WAS root patched with Ventura, then I bought the new GPU, reverted the root patch, swapped GPU and updated to Sonoma. I did a clean Ventura install without any root patching just to confirm it's not related to Sonoma but behaviour was always the same. OK - did all testing so far with my "bad" EFI and no VT-d in BIOS so - I can check if I still have that SSD with the clean Ventura.

And yes - I was not expecting thousands of users jumping on to this topic serving the perfect solution on a silver platter. Maybe some day someone will stumble upon this thread having either the same problem and/or a solution. As I said - this is not a mission critical issue. It's more a cherry on the top thing.

At least one (well there are a few more...) good outcome of this whole thing:

Driver: com.apple.DriverKit-AppleEthernetE1000

So I hope this means VT-d is enabled. Because sudo dmesg|grep DMA outputs nothing...
Either way - one "3rd party" kext more I got rid of.
