Sudden reboot after connecting laptop through HDMI to Dell P2421D

[TokerTheTalker]

and is this photo the same thing or more code to be disabled?

 

[Feartech]

So am I supposed to enable or disable the lines here, or delete them completely? which ones? all of the lines that include sharps in them? what about the double sharps?

the double ones are comments

the single ones are the ones you want to enable by removing, depending on your hardware

hence the reason to check over:

those are the boot arguments in your config.plist

 

[TokerTheTalker]

Then how do I know which ones are those that should be deleted? where is that explained in the Lilu guide? does it have something to do with Hackintool? I already have all of the Lilu kexts. Where exactly in that guide should I read and how would it help me?

 

[TokerTheTalker]

Sorry for posting many questions, I just want to understand precisely what I have to do.

yes, use hackintool to see which ports light up in green, also test the other 2 boot arguments

hackintool can also generate the patch required for your config.plist

hackintool, file export config.plist, if you point it to your config.plist, it will add in the patch for you

 

[TokerTheTalker]

And should I immediately try that config.plist? Is there anything else that must be done beforehand or afterwards? (besides testing the boot arguments)
