Hey that second screenshot is so cool! How did you manage to get BAR1 on your MAC? What command did you use?
I will have a look to see why it's not working, but I may need some more screenshots from you (look at the screenshots by Felix Chan in the other brightness thread)


That screenshot is from RWEverything from windows when I saved as plane text just to show the value. What else do you need?

I finally got QE with your FB and the natit kext on my Thinkpad T510 {onboard GFX only model} .

The only thing not working is one of the built in screensavers on Mountain Lion: "Shell"

The other screensavers work, and my system shows all signs of QE being enabled such as

Zoom effect when logging on, chess game working, water effect when adding widget to dashboard.

I was wondering if the problem with the Shell screensaver indicates a wider problem with QE?

I should also mention that my LCD baklight doesn't come on when waking from sleep, but I am about to start fixing that one.


Not really sure what you are talking about. The Shell screensaver works fine.

For some reason I can't preview it, just stays black.

When I look at a report from OpenGL Extensions Viewer, it tell me there is

No support for compiled vertex arrays - means nothing to me.

All tests complete OK in OpenGL Extensions Viewer and my install seems stable...

I have the same problem! I wouldn't have noticed if you didn't say. Shell doesn't work at all.

Also, my graphics are really "loud" under OS X. Things like scrolling or editing pictures generate this funny squealing noise (coil whine). I don't have this under Windows.. any ideas anyone

HI all,
unfortunately I cannot make the FB working, I tried all FB from this post:
http://www.insanelym...-graphics-qeci/

but nothing gave me positive results. I post my system log hoping verteks or anyone else will have a look at it.

Ive found a diagram of what edp looks like, maybe it will help us better understand the problem

You sure you guys can't see the Shell Screensaver? That is very weird. And you guys suffer from coil sound? My computer runs more quieter on OS X than on Windows.

I mean I use an SSDT for power management, but as for the screensaver, I don't have a clue unless I did something but I just wasn't aware of it.

Can you post your SSDT please?

The chirping sound (coil whine?) only happens when the GFX card starts working on something.

Interestingly, the noise is twice as loud when running on battery, not plugged in.

When I open Mainstage 2.0 it gets stuck on "initializing graphics", but I can still open a new project.

Redrawing elements inside mainstage, eg. adjusting graphic eq. is laggy, but the cpu usage doesnt go up.

Going to fullscreen in Mainstage doesnt work (I get scrambled screen for a second, then full screen mode exits).

However, if I change resolution to 1024x768 and then reselect my native 1366x768, full screen works OK.

Just a quick update:

Mainstage 2.2.2 goes fullscreen without errors and no longer hangs on initializing graphics.

However redrawing the interface is laggy and makes the "chirping noise".

Everything working fine, but how can i change this "Uknown" os-info to correct "Intel HD Graphics"?

You guys need to check your installation because it is not normal to get these chirp sounds or coil sounds on your computer. You sure its not the HDD that makes these sounds? Well sometimes you will hear clicks but that is normal because OS X is reading the disk.

My power management is fine:

As for my SSDT, I attached it here but you cannot use it. You need to create your own.

I haven't added this information either in my guide (at one point I will) but all you have to go is add your Intel HD Graphics information under GFX0 in your DSDT. Basically you use a DSM method in there.

This sound existed prior to frame buffer, so i doubt its the culprit, try different resolutions i have a feeling a single link lane on x1 width is just to much stress on the gfx........

example in linux i'm using a single link with x4 width ,but that config don't work under framebuffer.

This is Close to some power issue,like frequency voltage or something

For now check temps make sure nothing is over heating as this happens when the gfx receives a work load whether small or big.

Well coil whine is "normal" if there is too much power load on coils, i.e. bad power management
And i'm pretty sure its not my HDD cos i dont have a HDD :D
I do use SSDT though
In early macbooks, the coil noise was present and could be removed by a work around by disabling C4 state, but that decreased battery life so it was never an ideal workaround. People made apps such as ShhMBP to remove the noise, but all those apps had side effects. I wonder if its worth trying those apps out

are you saying using a dual link fb instead of single link could possibly help ?

pentothal I think I have an idea: I remember you were having trouble with your EDID with the resolution module, and RemC helped you with it, hard-coding it to use your "magical" edid. However, the problem may not be because of the framebuffer not working, but rather it's picking up a weird EDID. Do you have networking set-up? If so, do you happen to be able to use VNC to see if the framebuffer's working? If it is, then try creating an override with this thread: http://www.insanelym...splay-problems/ This will override any faulty EDID and use the one that works for you. Work using Method B, and see if this fixes the problem. Be sure to use your "Magical" EDID.
