Been searching a lot, but haven't found any posts describing this problem . . .

 

I have leopard installed on my new build and (almost) everything works great. I used the munky method for vanilla installation. I have a gigabyte motherboard, and a 8400GS 256MB video card. I am using the VGA output.

 

The issue is with the video card. I used EFI studio and have QE/CI working. I can change the resolution, but certain resolutions do not work. Whenever I switch to 1680x1050 (native resolution of display), I only get a blue screen. 1600x1024 works occasionally, but most of the time I just get blue screen. 1280x1024 works most of the time, but not always. I can be in 1280x1024 for many days, and then after a restart I just get a blue screen and have to search for a working resolution. Most other resolutions have never worked.

 

Also, It seems like text smoothing does not work. The picture doesn't look great. I can go into display calibration and move the sliders around and there is no change in the picture. Is this normal for a hackintosh?

 

Any ideas for solving this problem? Anyone have the problem? I have tried every kext/injector/solution I can find, but most just make video situation work. Soon I'm gonna get a DVI cable so I can test DVI out.

 

Any advice would be much appreciated. Thanks everyone for all the help on these forums!

After applying your EFI strings did you remember to remove ALL of your video injectors? Try using OSX86 tools to remove injectors if you haven't.

 

 

There is a wealth of information at the following link; http://forum.netkas.org/index.php?topic=222.0

 

EFI strings are picky sometimes. Let me know what OS version, kernel and modified kext's your using if the above doesnt help.

I had this problem as well, where after changing resolution I would get a blue screen with mouse pointer.

 

I think this happens when OSX or the video drivers get confused about where the primary display is. And you end up on the secondary display and there's nothing there because you didn't put anything there.

 

If you had already hooked up a microphone and activated voice recognition, at this point you could probably talk your hackintosh into switching resolution again and somehow end up back at the primary display. Or at least reboot in a less barbaric way.

 

Sometimes you can solve it for good by using the other output on your video card. Just plug your monitor into the other plug and reboot.

The above will almost certainly fix it if you end up at the blue screen when clicking 'detect displays'.

 

You might not need to buy a DVI cable - you can probably get away with using a DVI to VGA adapter. Not sure though. You should have one of those already, they usually ship with the video card. Try it.

 

Sometimes that won't work either. Then you'll have to modify your NVCAP value which is a little more work. The NVCAP value informs the driver about the order of your displays. It's part of your Device Property String, or inside your injector extension. There's a great thread started by krazubu in the nvidia subsection of the drivers forum about this.

 

/EDIT - Krazubu's guide can now be found on the ProjectOSX forums - thread title is "Guide for all nvidia boards".

Thanks a lot for the help.

 

I created a new EFI string (per the instructions in Searay's link), and got the same result. (I am adding the EFI sting to my EFI boot partition, which gets loaded at startup).

 

I also tried adding it to the startup disk Boot.plist file, but that didn't work at all (no QE/CI, only one resolution).

 

Beerkex: I normally solve the problem by screen sharing from my macbook pro and changing resolutions until i find one that works. I'll look into the voice recognition, might be useful.

 

I have the DVI-VGA converter that came with the MBP. I plugged it in once, and there was an image but it was very blue-tinted and dull. Changing color settings had no effect. Maybe I'll try again with some new settings to see if I can get a better picture. Does anyone know if this a standard adapter? I could see apple designing one that would only work with their hardware.

 

More info about my setup: Leopard 10.5.6, vanilla kernel, ASUS EN8400GS Silent video card.

Beerkex'd is right; OS X is "confused" about the primary during resolution changes and the NVCAP values are a good starting point.

 

TIP: You may already know this but the general rule is that the primary port is the one closest to the motherboard

 

A lot of cards have 1 DVI and 1 VGA port with the VGA being the one closest to the motherboard but many of the 8400's Ive seen have the VGA as secondary (furthest from the motherboard) - is this the case with yours?

 

I use the DVI to VGA adapter that came with my MBP on various machines with no issue so I don't think Apple has deviated from standard there (or at least with my version of the dongle).

 

Even if the picture is dull try the adapter anyway and see if you get the desired outcome (obviously with the exception of the bad picture) then at least you'll know for sure what the issue is and what you will need to do to fix it.

 

I will add this; I once had what appeared to be a somewhat bad VGA cable that would cause the screen to freak out occasionally and resisted resolution changes (black screen) because after I replaced it everything worked great.

 

Once again though, check for natit nvinject and nvkush to make certin none are loading. They can cause this behavior if your using EFI strings.

 

 

Regards,

If you scroll down to 'connectors' you'll see that there are 4 different types of DVI:

 

http://en.wikipedia.org/wiki/Digital_Visual_Interface

 

So I would say it's very possible that the MBP adapter isn't compatible with your video card.

 

You could try to find your 8400GS at the manufacturer's website, if you're lucky there'll be a photo of the contents of the box where you can see what the VGA/DVI adapter looks like (if it came with one at all). If you can see the DVI side you should be able to identify which type it is.

I can't get to this thread anymore for some reason (wtf insanelymac. So many good threads have disappeared..why?) but this was THE thread about NVCAP values:

Maybe google cache still has it.

i loaded osx with efi stings and nvinject and nvkrush, i removed nvinject and nvkrush and used UInstaller to load the EFI strings

 

I also had the same issue with the light blue screen, and had issues switching resolutions and i had issues with the vga port and even after rebooting with the dvi port the same light bluescreen but evently after rebooting and trying differnt things it evently let me back into OSX at the 800x600 and i was able to switch to any resolution with out the issue but a new folder appered in the main HDD DAMAGEDFiles with these files:

 

0000003c fseventsd-uuid

 

00032ac0 com.apple.Bezel.Services.plist

 

00032ac1 com.apple.loginwindow.plist

 

0032ac4 mdsObject.db

 

0032ac5 mdsDirectory.db

 

00032ac7 utmpx

 

00032ad2 configd.pid

 

00032ad3 diskarbitrationd.pid

 

0032ad4 DirectoryService.pid

 

0032Aad7 flatfile.db

 

0032ad8 index

 

00011200 SystemEntropyCache

 

but every thing works fine

@jig88

 

i don't suppose you could more explicitly explain what you did to get it working?

 

i have the same card as you and i'm a little stuck, if you could post your in.plist you fed to gfxutil that would be fantastic or even point me in the right direction.

 

:] thanks

I just did a fresh install of Snow Leopard using nawcom's ModCD (thanks nawcom). I have an nVidia 8400GS PCI with full QE/CI using only chameleon's GraphicsEnabler=Yes. Using the VGA port, if I change resolutions, the desktop gets stuck at a blue screen. After waiting over 20 minutes, I gave up and rebooted. Snow Leopard booted up normally, but whenever I try to change resolution, I get the blue screen.

 

When using DVI, I can change resolutions just fine. However, the monitor I'm using with this system does not have DVI. Is there any solution to fixing this for the VGA port?
