hmm huh im confused now... can u do that epitorus in DSTD like mrroboto sayd

[macprodan]

I am glad to see some people working on this issue. I have a MacBook Pro but would like to get OS X on my parents Sony Vaio NR21 with 8400M GT for them.

[Milance]

epitorus is only one hope for us ! vaio users

Well, I'm impatient and I think I could possibly help at this point, so I'm installing OSX again. There's another thread where a person was able to adjust screen resolution, but (maybe) still no QE/CI. http://www.insanelym...amp;pid=1115065
I'll keep everyone updated.

Yep screen resolution can be changed, mine is set to the correct resolution that i should have, but of course the problem still remains with no graphics acceleration, thus QE/CI not working

Is there a chance that Epitorus' kext works...but we do not have the correct NVCAP value? Seems the best test would be with the kext and trying vary nvcaps

[anomie]

well, i followed "Code#"s steps from here

Post #9 (not his first one since that didn't work for him)

i am able to at least adjust the resolution and the special effects may be handled by the processor and RAM, rather than the video card. i am not 100% certain. i am about to mess with QuartzDebug and see what's going on. so far, i'm happy...better than my first attempt installed 6 months ago when i couldn't even adjust the resolution, or if i installed an nvidia solution, i wouldn't be able to see anything on my laptop..

Well, "Enable Quartz Extreme" is grayed out in Quartz Debug.

Under System Profiler, I get:

NVIDIA GeForce Go 7400:

Sweet!
This thread i going to the right direction!

Should the CI be set at Software?

Quartz Extreme is only supported if open GL is supported..right?
I would really like to get it fully Open GL support!
So I can run Autodesk Maya and other cool stuff!

Great job everyone who are trying to solve this issue!! Kisses to you all!

THANKS for THIS!

I'm looking into ways people not using VAIO's resolved issues with "Quartz Extreme Not Supported" with video cards that are capable of supporting it (nvidia 7xxx Go's should be fine). This may end up being a different path than the original poster (Krazubu) suggested. I think we're all looking for the same solution though.

Awsome! but the QE support is going under Display support..right?
How is it with the CI? It supposed to be hardware..right?

This is possible to make this work..right?



I'm a newbe, so I might say stupid stuff!..spare me =)

QE should say supported if its working, and yes i do think it needs OpenGL to work as well, and CI should not say software.
And yes, it will eventually be possible to work.. hopefully

alright!

Hopefully someone can fix these issues aswell!

In other QE & CI issues (other cards and brands) how where they solved? Is it harder than the working snc driver now?

I also wounder..can you clone the display to vga aswell without any problem?


and again guys! good work! keep it up!

[Suslo]

cross fingers and pray...

Hope you can solve this ...GL all who works on solution and THX ofc

Here's an option I just discovered.
http://www.insanelym...showtopic=64656

I was able to enable QuartzGL which seems to be an (buggy) alternative to Quartz Extreme for boosting visual performance. My windows move quick and smoothly now, the Genie effect works smoothly, dashboard flies in without any slowdown.

System Profiler after enable QuartzGL:
Core Image: Software
Quartz Extreme: Not Supported
QuartzGL: Supported

My next route to try to enable QuartzExtreme is uninstalling Macvidia (old solution, but the fact it works partially gives me hope), and messing with the 7400go EFI string installs.
http://forum.netkas....I...&topic=55.0

More info about QuartzGL:

The technical requirements for Quartz GL are are explained by Q&A 1536 <http://developer.app...07/qa1536.html>

What it does is it causes window contents to be rendered using OpenGL rather than the window being composited in software and then uploaded as a texture (which is Quartz Extreme). Depending on your window's drawing patterns, this can increase, decrease or not affect performance at all.

I have the same problem and tried all drivers. My monitor turns off if I try some good drivers.

[anomie]

The EFI string (and NVCAP) method is a bit hard for me to understand. The link I provided supposedly had the EFI string for 7400go, so I put that in the boot.plist file, uninstalled Macvidia, etc. but the display went back to 1024x768. There are 2 7400go though, one is 256MBVRAM, the other, mine, is 64. Not sure if they would produce different EFI strings. Need to take a break for a few days. Fairly happy with the state of my setup, it's just fullscreen video playback is terrible (tried Quicktime, VLC, and MPlayer) and a few of the CoreImaging features don't work, like a translucent menu bar, the ripple effect when adding dashboard widgets, etc.

[anomie]

why don't you try to modify DST with DSDT patcher instead of making a full kext? should be easyier at least for testing, isn't it?

Actually, I missed this post before, looked more into it and found this DSDT thread by "fassl"
http://www.insanelym.....pic=133683%22

He seems to believe this is the route to go, perhaps the only problem is the lack of people with VAIO's, like most of us following this thread, actually testing it out. I'll look into it myself after I finish my taxes.

[Blackshore]

Thank you guys for making progress on this issue.
I truly admire that!

[Enrico85]

I've try the kext for SNC and appear to work but for me the problem are the display driver. ok the switch work but leo not recognize the display because not find the display.
And now the secret for me are the overrides.
What do you think?
