Displayport issue

[ChewyJetpack]

I had this running perfectly for a couple of days on my T440p. Tried to connect an external monitor via the mini-DP port and the laptop screen goes blank, no signal on external monitor, and signal on the laptop screen does not return even after the cable is disconnected. For the last two days, external DP monitors have been working fine.

so it worked before and it's not working anymore?

[ChewyJetpack]

Yes, it worked this morning in fact. I've tested with multiple monitors and cables.

I really appreciate any help on this! Your repo has been extremely useful for me :)

[jloisel]

You should try to ask for help on hackintosh forums. I can't really help: if it worked before you obviously broke something which causes the issue now.

I have investigated this further and discovered that actually nothing had changed. It works with a mini display port to VGA adapter, however the problem is present when using a mini display port to DVI or HDMI adapter. In both of the latter cases, the laptop screen turns black and won't return until the machine is restarted.

Not sure what can be done, maybe it requires further ACPI patching or a fix in WhatEvergreen kext. Ask on InsanelyMac, they may have solutions to this problem. If any solution is found, i'll integrate it here.

[ChewyJetpack]

Thanks, I will look into it

I have a fix here:

KextsToPatch:

AppleIntelFramebufferAzul - 01050900 00040000 87000000 - 01051200 00080000 87000000
AppleIntelFramebufferAzul - 02040900 00040000 87000000 - 02041290 00008000 08700000

[jloisel]

Where did you got it? From my understanding KextsToPatch is no longer viable in Mojave (at least for Skylake cpus and above). Most recommend using WhatEvergreen + Lilu (that's the case here).

[ChewyJetpack]

I was recommended to me on tonymac86 in the t440p thread. Given the t440p runs Haswell, Skylake compatibility shouldn't be an issue. I've tested it and it works flawlessly. Also, there were other entries in KextsToPatch already, so your current config is using it.

[jloisel]

Can you provide the entries from your config.plist directly? It would save me some time to update the repo.

I also have problem with mini display port, on Mojave Thinkpad t440p. I did not display anything, and the OS freeze immediately and sometime got very lag . Can you help me to fix this problem ? Should I run patch code like above. or,... doing something to fix this....?

Add inside KeysToPatch in config.plist

Okay thanks!
