Hi,
Use the latest Nvidia CUDA drivers

[Matias Kottwitz]

Hello and tried CUDA drivers  and not work

[mediamac]

Remove all other Nvxx drivers before installing.I have same problem and i have 8600GT.I removed all enablers and inject from extra/extensions and i removed all nvxx kext in system extensions.Then installed latest CUDA and it worked for me.You should try in -v -f mode.Make sure you get this NV50hal.kext loaded and registered.

[Matias Kottwitz]

Well I will try as you say

[mediamac]

You know this BACKUP before further proceeding

[Matias Kottwitz]

try the cuda driver as I said and did not work

[Gringo Vermelho]

Of course not.

Your advice makes no sense. CUDA drivers don't do anything unless you're running apps that make use of CUDA.

Gringo Vermelho is right, out to investigate

The problem is very simple to solve. Don't do nothing. After the fresh install of ML, just boot with "UseKernelCache=No"

If it works, add "UseKernelCache=No" to the Kernel Flags in your org.chameleon.boot.plist

Actually i attempted to install many NV kexts nothing works but after installing CUDA it works so i suggested that. May be i am wrong and missed the main part.

Thanks

What do you get? A desktop without acceleration or no desktop at all (just hangs)? What is the last 5 lines that you see when booting with -x?

Gets No nothing, no acceleration, no Quartz, nothing, only shows that the video card has been identified but not enabled ..

People already solved the problem by a user who helped us, one must place the "NVDANV50Hal.kext" of DP4 verify who is registered and loaded, then use the "NVENABLER.kext" with EFI strings in org.chameleon.Boot.plist and GraphicsEnabled = yes and it works perfectly if you have a kernel panic, put your device id in your "NVDAResman.kext" Thanks to all ...
