VAIO PCG-11211L Black Screen (Geforce 310m) ML 10.8.2

10 November 2012 - 05:23 PM

Hello,

I got this nice machine from a friend. After trying to install ML on it for a whole day with no success I decided to clone my already working 10.8.2 installation running on a GA-Z77X-UD5H onto a disk and plug it into the Vaio.

It boots without a kernel panic but to a black screen. If I boot verbose I can see the text freeze after the [PCI configuration begin]

I know the machine is up and running cause there is disk activity and it responds to keyboard strokes. I booted it into SUM and although the text was frozen on the screen it rebooted when I typed "reboot" and hit Enter.

So, I'm pretty sure this is a GPU detection issue.

It has an i5 CPU, Geforce 310m (ID=0x10DE0A75), Atheros Wifi, Realtek Audio, and a touch screen.

So far I have tried multiple boot variables such as PCIRootUID=0/1, npci=0x2000/3000, GraphicsEnabler=Yes/No, UseKernelCache=Yes/No both with and without -v/-f/-x/-r . But the result is always a black screen right after the [PCI configuration begin]

I have tried one NVEnabler.kext and it gives me some scrambling colours on the screen. This is the only way I'm able to see anything on that machine's screen.

I have also tried adding the device ID "0x0A7510de&0xffe0ffff" to both NVDAGF100Hal.kext and NVDANV50Hal.kext to no avail.

Any ideas?

Help is really appreciated.

Thanks
