In Topic: Black screen on boot after graphics card upgrade

Enable nVidia drivers http://www.insanelym...nvidia-drivers/


I dont think injection is required now that native nvidia drivers are released, but none the less i'll give it a try. btw i do not currently have a dsdt as i never needed one with my old graphics card. thanks though :)

You are using old release candidate of Chameleon, get newer 2.1 for starters


-v -f GraphicsEnabler=Yes PCIRootUID=1 npci=0x2000



@eep357 I updated to Chameleon v2.1svn r2069 and it still didnt seem to make a difference at all on boot. although now when I boot it shows a grey background with cursor and freezes shortly after :/

@iFIRE I just tried the boot command u mentioned gives me a black screen, however after chameleon update with the same command it displays something but only grey screen with cursor and freezes shortly after.

Personally I made the effort to reinstall the Nvidia drivers namely GeForce 295-1.00.05f03 for 10.7.5 and CUDA 5.0.36 which still makes no difference at all but grey background with cursor then freezes shortly after. looks something like this btw http://imageshack.us.../imag0418p.jpg/

So any idea whats preventing it from displaying? I meant booting from safe mode works but it freezes after some 3-5 minutes of use after flickering on the screen which fortunately gave enough time to install the Nvidia drivers thanks to SSD. As a note when booting from safe mode under -v I recongize a line going by very fast saying NVDAsomething recongized and loaded so the driver should be loaded but some how decides to freeze either in safe mode or not to display anything at all seemingly weird.

Again thanks for those who helped btw :)
