GTS 450 Updated to 10.7.2 Black Screen

[PooyaNabei]

Hi Guys,

I've been looking for a solution and can't find anything. 10.7.1 was super stable with no EFI STRING edits and no GraphicEnabler, updated to 10.7.2 and I got the black screen, even with graphicenabler=yes.

I found this solution but can't find a way to apply it. PLEASE HELP!

Replacing:

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

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



THANK YOU!

It's a DSDT fix. If you're using DSDT injection you can apply this fix.

Thanks so much replying, do you know of any other fix?

There's some user who was able to use the fix in efi strings by just changing NVDA,Geforce to NVDA,Parent before converting into hex. Didn't work for me though. Still can't use my DVI in any OS X version.
