The topic title is self explanatory: let's post here descriptions of our problems and possible solutions. Try to describe using the most details you can, posting complete specs, kernel, boot flags, pics and videos.

P.S.: ATI users also have been experiencing some issues, yet they actually have an usable system. Since it's not the case with nVidia users, let's keep this particular thread about nVidia-specific problems with Mountain Lion and Lion 64-bit legacy kernels. Thank you.

Have you tried switching to an Imac SMBIOS? Ive always had good luck with Imac 12,2 with my GTX550 TI however some reason typing in a SMBIOS manually doesnt change the system for me.

I suppose you could always just mess with the applegraphicspowermanagement.kext and manually add your card in for whatever your system is being read as.

Can your AMD system boot 10.8.2 with a nVidia card without -x? That's amazing, because you must be the only one, seriously. Congrats.

I did some experiences using nVidia kexts rollback both to 10.6.8's stock kexts and 10.7.5's.

With 10.6.8 nVidia stock kexts (i installed all of them, regardless if they are specifically for my G210 or not), i could boot without -x, but i got no QE/Ci, only native resolution (in my my case, 1080p). The System Information and System Report both reported my card correctly as a G210 1024MB, and told me the drivers were up and running, yet i had no graphics acceleration, much like as i boot in safe mode. Here's some pics:

With 10.7.5's stock kexts, my system boots straight to a white screen with the mouse pointer cursor frozen at the top left corner of the screen, plus a pin wheel spinning at the center of the screen (not to be confused with that rainbow colored Beach Ball of Death, this one is the same that appears on a white/blue screen when you start or shut down the system). Obviously no pics here.

In both cases, i was using the latest amd_kernel from Andy Vandjick with this org.chameleon.Boot.plist:

One perhaps useful information: every time, with every kernel or kext set i used, that i tried to boot without GraphicsEnabler or with it set as "No", i boot straight to a black screen. That happened regardless i used safe boot (-x) or not (maybe the kernel or something else is not reacting properly to the boot flags at all, who knows?).

Here are my observations from an XFX nVidia GeForce 7600GS 256MB.

Mac OS X 10.6.8 32-bit kernel 64-bit userland: QE/CI works perfectly.
Mac OS X 10.6.8 64-bit kernel 64-bit userland: Untested.

Mac OS X 10.7.5 32-bit kernel 32-bit userland: QE/CI works perfectly.
Mac OS X 10.7.5 64-bit kernel 64-bit userland: frozen cursor on white screen.

OS X 10.8.2: hangs before loginwindow.app opens.

No, sorry for the confusion. Mine, much like your machine also has issues. My post was just an idea to get it to work and to see if your system would respond to a SMBIOS change(as mine doesnt) then in that case possibly you could test it and post your findings....Im not sure about your video card but for mine with lion there was edits with AppleGraphicsPowerManagement.kext that could be put in for proper QE/CI.

Now as for my findings in detail...

I can only boot with -x, when doing so I have full native resolution, also 1080p in my case, but no QE/CI. It lags and chops between screen animations such as launchpad and showing notification center(shows quite a bit of red)

When doing "GraphicsEnabler=No" its supposed to be Vanilla, and it should work for us(at least me, im not sure how your card works in ML and I cant speak for all) and it should run just fine, so there is a communication error between the kext and the kernel.

So until that is...fixed...we have to use Yes.

I see that Spakk has the same video card as me and they posted in the Working builds section a ML kext for our cards...i reached out to them to see if it is worth messing with or if they are in the same situation I am still in (only can boot -x, GraphicsEnabler=Yes, no QE/CI[even though the card is recognized and natively supported, however Is there QE/CI in safe boot? im not sure?])

Anyway, thats my ramblings.

Edit:
Hey quick question, when you boot with GraphicsEnabler=No what happens? mine loses signal to my monitor.

EDIT2: I see you have a wake parameter...what is that exactly? do you have sleep working properly? I thought that would have to be re-done with sleepenabler since ML on AMD is so new. Does an old one work with this? Sleepenabler works great with ML on my system.

Please don´t forget that ATI Users have also graphic issues.

[Deltac0]

Lol, posting about ATI @ NVidia thread

The NVidia is more critical IMO, they can't even boot without safemode.
I feel sorry for them.

Has anyone tried Lion with ATI / NVidia and the x86_64 kernel? Same issues?

[wastez]

No, Lion is working very well

[Andy Vandijck]

Has anyone tried using the gfx drivers and bundles from Lion on ML?
10.7.5 has the same graphics family as ML so it could work.
For NVidia users that are the NV and Geforce parts...

[theconnactic]

I tried, Andy! See please post #3.

Yes, like theconnactic tried with the 10.7.3, I also tried using Spakk's linked GTX550 TI kexts in the AMD working build thread which is a collection of Nividia and geforce kexts. I looked them over for differences, they were a bit different but they didnt work any better than the stock kexts.

Tryed that on ATI Drivers ended up switching form a white to a black screen !

After what i found inside NVDAResman.kext, i'm almost sure the nVidia issues are cupid-related. What a joke, since all macs have Intel CPUs...

What about IOGraphicsFamily?
Have you tried switching that and the IONDRV one,also?

[theconnactic]

Didn't understand, Andy: you mean switch from ML IographicsFamily and IONDRV kexts to Lion's ones? Do you think this by itself can be a solution, or it should be done alongside replacing ML nVidia kexts by Lion ones?

I think the best solution, perhaps, would be replacing the CPUID instructions inside NVDAResman by nop instructions, but i confess i don't have that much experience with binpatching, so i'll try your idea first.

Best regards!

[Andy Vandijck]

Also the bundles and graphics kexts (NV* and Geforce*)
It could work...
I'll check the use of cpuid in NVDAResman later..

[theconnactic]

Testing now, will report back in a couple of minutes.

[wastez]

I took the IOGraphicsFamily from Lion.
Doesn´t change anything.....

[theconnactic]

First test (only -f): the desktop never arrives;

Second test (-v -f): i cannot see any sign of the NVDA kext loading, console output continues forever, no desktop;

Third test (-v -f GraphicsEnabler=Yes): panic with kextd. As it happens randomly, i'll perform the same test again. Done: same as above;

Fourth test (-x -v): as extensively described before, the system cannot reach the desktop without the graphics kexts even in safe mode with AMD ML kernels.

Now i'm going to try the following: since i installed the Lion kexts on the ML HDD when running Snow Leopard, i'll boot again, repair permissions in the ML HDD (one step i missed before trying to boot) and perform the same tests again. Done, no luck.

[akimoa]

well i had another test on ati with all kext from 10.7.5 http://cl.ly/2s021m3S0q1T

got in this time (cause i forgot some on the 1st go )

only non Lion bit in ATI is the new Accelerator !! .. but GUI probs havent changed sadly

not ment to spam the nvidia forum

rite did another test with Lion kexts got rid of the AMDRadeonAccelerator.kext

device in Slot 1 was back at boot

and i got in without qe ci but full resolution wich didnt work on ML kexts !
