10.7.2 Black Screen

[PooyaNabei]

Hi guys,

I just updated to 10.7.2 and I'm geting black screen after restarting. I found a few solutions

Replacing:

"device_type"
Buffer (0x0D)
{
"NVDA,Geforce"
}

with:
"device_type"
Buffer (0x0C)
{
"NVDA,Parent"
}


but I can't find the line in my dsdt.aml


Any helps please?

Thanks so much,
Pooya

Yes, it is the solution for solving black screen, you are on the right track. However, It is not inside DSDT.aml

It is EFI String that you need to convert it to hex code using GFXUtil and but inside com.apple.boot.plist.

Try to google some tutorial about how to use GFXUtil.

EFI String solved my Graphic Card Black Screen problem for my ASUS EN210.
It also solved my iCloud "Valid but not iCloud account" problem by Ethernet EFI String

Hey,

Thanks for the reply, but I'm completely lost. Is there anyway you, or someone can guide me through it. I never messed with EFI STRINGS.

Thanks,
Pooya
