I'm a Alex's colleague, with the exact same laptop and  I have tried several different boot/kernel flags.


The once I tried : GraphicsEnabler=Yes/No (both), PCIRootUID=0/1 (both), SkipNvidiaGfx=Yes/No, -x , -v (no resolvable errors) Still only output on external display (I tried every flag without the external display plugged in.)Does anyone know how to use the flags display_0= and display_1= ? Is there a way to figure out wich Hex key to use (or how to retrieve it) for the internal display, or are we forced to edit the DSDT, wich I have never done before, so hints are welcome.


I've seen a different post about making a change to the DSDT regarding Nvcap being wrong in de DSDT, I'll try to test this, when I can....

Also on my PC same issue.




Processor  2,99 GHz Intel Core 2 Duo

Geheugen  16 GB 0 MHz FLASH

Videokaart  NVIDIA GeForce GT 640 2048 MB

Software  OS X 10.9.1 (13B42)


Currently i have Mavericks installed with MyHack 3.3

There i have no issues.


When i start the Niresh Mavericks installation i see the boot screen and after that i like to see the white setup screen but instead i see a black screen.

It looks like a Niresh issue because other setups works,
