yeah me too please post the actual kexts that work for you,Idon't have dp2, old 10.7 kexts work for installation but don't work after replacing them when system boot.
do you replace "NVDANV50Hal.kext" only or "NVDAResman.kext" too !!!
also what about changing our dev id in DSDT to "GT 330M" , i think this will load the new kext

thanks

[Peter_sm]

OK, here are the kext from DP2

If we help out each other we might solve our issue :-)

Thanks will try these and report back.

So far I have tried the following:
1. if I remove the NVDAResman.kext then It boots quiet fast to the desktop but resolution stuck at native1280x720.
2.I added my device and vendor id to the info.plist of applegraphicspowermanagement.kext using the macbook pro6.1 smbios but no go.
3.injected the device id to info.plist of NVDANV50Hal.kext at pcioprimary match string but still no go.

Irritating thing is that for me,it sometimes boot out of the blue after 7-8 attempts sometimes even without the kernel commands and runs perfectly fine to fail at next boots.

So I guess graphics do work but they are not loaded or its a kernelcache issue ,mine is a gt320m


PS.
some other thing could be;

change in graphics card injection in dsdt like we had from snow leo to lion (m lion has a native and scaled display option)

@Yehia
you need to replace all 4 as the dp ones are are twice the size cos they seem to be both 32 and 64 bits extensions.

And good news ,,with the dp2 kexts everything works as before ,no boot flags needed,boots in 30 secs.
But this has to be a temp fix,as the 10.8 kexts are pure 64 bits and should work as is in our systems.
Need a pro like taptun or nixin to look into the dsdt part for mount lion.

This problem is being reported by a lot of folks and even on desktop systems so hope some one fixes it soon.
Any more suggestions are welcome.

[Peter_sm]

Remove the 5 NV kext and replace these with the 4 from DP2 ;-)

i updated to ML it works good after replacing Kexts thanks to Peter
but it's very slow in booting, anyone face the same problem !!

[chrispypatt]

I am having problems booting my install USB. I keep getting a black screen after everything loads. I replaced the Graphics kexts with the ones forrm DP2 and am using all the flags to boot. Anyone want to share how they got it to work?

Delete extension.mkext from your Extra folder and any of its backup ,
then generate a fresh .mkext using kext utility
install this chameleon--
http://www.insanelym...ch_id=111668---
Repair permissions on both Extra/E and S/L/E usig kext wizard.
Reboot
Remove any unnecessary kernel flags in org.chameleon boot.plist

use -x -f -v graphics enabler=yes usekernelcache=no , to boot, will need a usb mouse as -x wont load voodoops2controller kext.

try a couple of boots if you still fail then boot with -v alone,

you will need cpus=1 if booting with vanilla kernel or replace vanilla with the lapic fixed kernel on the usb itself to boot without cpus=1

. use dsdt,smbio.plist and org.chameleon.plist as in lion on the usb.

hope it helps

I tried to install original NV kext again, this is how it works

1: From LION install all 5 original kext from Kext Wizard
2: fix permision and rebuild
3: boot to ML it's OK good FPS about 55fps
4: reboot to ML again
5: It's STOPS!!!


with kext from DP2 my fps is about 35fps.....


What can be change between this reboots ?

[chrispypatt]

I got ML installed on my laptop and I can boot using -x as my only boot flag. The problem when not booting in safemode is that the boot hangs at the grey screen. I have my mouse on the screen and can move that but the screen is stuck on the grey background. Any help?

As I said before it could  be a kernelcache issue,cos you were able to boot once that means graphics are ok(for me if I keep trying it does boot,all vanilla  kext,but not always).
So some how the cache is lost at next boot .

[Peter_sm]

is this a issue in ML

No Kernel Cache File '/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache' found

In LION I have a kernelcache

Solved: After running manually, i saw some kext thar prevent to build the kernelcache

How can you tell what kexts are preventing kernel cache? And so with those kexts can you repair the original kexts and run smoothly? How do you build a kernelcache.

Boot with -v and give us the last few lines. It will probably be "dsmos has arrived" in any case it will help us to help you.

@Kasi99
use graphics kext from dp2,the ones posted in post 1323 above on this page,use kext wizard to install them backing the original kexts and repair permissions and reboot.

@Peter_sm,

after generating the kextcache manually,are you able to boot properly with subsequent boots using 10.8 vanilla kexts.

[Kasi99]

Hello @macp!

I have Intel HD graphics!

and not NIVIDA!
