10.6.3 Update + 9800GX2 = Black Screen!

Smith@@™ · May 13, 2010

Hi All

I've just noticed when I set my display settings to 'mirror' I get an output from one DVI port and a blue screen out of the other.

Just thought I'd share in case this is linked to your problem.

NB:- when not set to 'mirror' I have no problem, main desktop on one monitor and desktop 2 on the other!

You need of these two for your vga, or in dsdt or in evoenabler:

"@0,display-cfg",
Buffer (0x0B)

{

0x03, 0x01, 0x00, 0x00

},

"@1,display-cfg",
Buffer (0x04)

{

0xFF, 0xFF, 0x00, 0x01

},

thanks smith I'll give it a go.

thanks smith I'll give it a go.

No joy I'm afraid - I have add this to DSDT, note I still have to use GraphicsEnabler=Yes or I get no video output.

           }

Although I have noticed that I get far smoother GFX with the DSDT addition. Video playback is notably less jittery !

D.

EDIT ... NB - GraphicsEnabler=No and GFX string also works for me but still same issue .. no big deal for me just thought it might be relevant here!

I have this:

"@0,display-cfg",
Buffer (0x0B)

},

not this:

"@0,display_cfg", ---> underscore? Why?
Buffer (0x0B)

{

0x03, 0x01, 0x00, 0x00

},

Anyway look here and here

Your problem, mirror on desktop, for my 9800gt, 8600gts and 8800gt, i resolved in this way. And it is strange that with your vga this "way" don't resolve the mirror mode.

Try other combination!

macbook pro 8600GT : 03010000 - ffff0001
macbook pro unibody 9400 : 03010300 - ffff0801

macbook pro white 9400 : 03010300 - ffff0201

mac pro 7300GT : ffff3600 - 00ff3e01

mac pro 8800GT : 03010000 - ffff0001

imac 24" 7600GT : 03035000 - ffff3601

Apple TV 7300Go : 01ff0000

powermac 6800GT : 00ff3e01 - 00ff3600

Ciao;)

You know I've bee using DSDT for my GPU for a long time but have never managed to get this GTX260 to work with only DSDT .. Only EFi string as per PCWIz guide here or GraphicsEnabler=Yes

I've seen that barnum clames a DSDT fix here

But it doesn't work for me ..

Having looked at PCWiz's properties.plist for the GTX260 the major differance i see is that he has the rom version set to : 3172a (actual) not "nVidia GeForce GTX 260 OpenGL Engine" as everybody else seems to have ..

Anywho 3172a - is the fix - currently booting DSDT injection for GPU and guess what .... mirror displays works !!!

This works for GTX260:

Ok, i don't understand many your english, but this:

Having looked at PCWiz's properties.plist for the GTX260 the major differance i see is that he has the rom version set to : 3172a (actual) not "nVidia GeForce GTX 260 OpenGL Engine" as everybody else seems to have ..

it makes not difference, nothing, it's only "esthetic".

The only noticeable difference is that I have posted, on my, if i write to rom-revision: blablablablablabla god is good, instead "nvidia geforce etc." all works the same, the mirror works the same.

This is the right:

"@0,display-cfg",
Buffer (0x0B)

{

0x03, 0x01, 0x00, 0x00

},

and this:

"@1,display-cfg",
Buffer (0x04)

{

0xFF, 0xFF, 0x00, 0x01

},

Differences that you have correctly as I have shown;)

You do not show me "air", I realize this

Ciao

LOL looks like you're correct ... I was a little bit drunk when i did this

+1

I too have just upgrade to 10.6.3 and I have the same problem.

When I connect to the TV via the DVI / HDMI connection the system boots to a black screen.

When I connect the video out to an old CRT monitor the system boots normally.

I am running a EN9800GTX+ DK/HTDI/512M Asus card in an AMD system.

This setup worked 100% under 10.6.2 with EFI strings.

10.6.4 is now out, has anyone who had the graphics problem updated to this one? I would like to know if it will work with XFX GeForce 9800GTX 512 before I do it because cant be bothered reinstalling...again :rolleyes:

cheers!

defn · June 18, 2010

EVGA GeForce 9800 GTX+ here and I'm getting the black screen under 10.6.3.
