Good night everyone,

I've got most of my devices fixed, but I have a lot of trouble with the laptop display.
It's an HP EliteBook 8540w with Intel i5 and ATI FirePro M5800.
I'm on Mountain Lion 10.8.2, dual booting with Windows 7 from the same drive.

ID: 1002:68c0
Hardware Info does not recognize it, System Info says it a Madison, Mobility Radeon HD 5000 Series.
Wikipedia tells me its based on Mobility Radeon HD 5730, so that can be correct as that one has codename Madison.
I use ATIController5000.kext for it. I don't think I changed anything in the kext, my device id was already in there.

I can boot with GraphicsEnabler=Yes or with GraphicsEnabler=No, it doesn't make a difference.
After the verbose logging, when its finished starting up, it tries to display the login screen, in the right upper corner a few pixels start turning greyish like a quick sunrise.
After less than a second it all turns black. It only reaches a few centimeters.

After verbose logging the external screen (AOC 1080p display, VGA) is detected, I can also VNC when the external display is disconnected.

I have tried this:
http://www.insanelym...splay-problems/
And this:
http://www.insanelym...page__hl__ 68c0

That thread used a 1002_68a0.rom, I tried looking for a 1002_68c0.rom, but it was only available on a Chinese website, so I couldnt register to download.
I tried to rename it, but it did not work for me.

I'm really desperate, I don't know what I could try anymore. If anyone could help me out that would be great.

-tb

DSDT injection should work. I changed the device ID to match a ATI 5730 which is natively supported. Framebuffer Vervet seems to work the best but not always... You may have to mod the frame buffer. See guide in sig.

Thanks for your reply Rampage,

Ive added your piece of code to my DSDT and tried Vervet bootloader. It gives me 12 tiny screens, and it makes mac actually detect my display in displays.
I took a look at your blog, I tried to mod Zonalis because that one had 6 and my ROM told me I had 5 entries, no luck though. I even broke my VGA with Zonalis, which works on Vervet.
So Ill steal the VGA from Vervet soon, my display is an EDP, this is Embedded Display Port, I tried this as DP, is that okay or should I try the laptop screen?

Also if you could give me heads up on making 12 tiny screens one large screen, would be great, otherwise Ill try again tomorrow.

Really liked that blog post, very usefull, its hard stuff but very intresting.

Changing it to laptop port doesnt work for me either.

Went away on vacation for a few days so couldnt check any sooner.
I managed to make it show 4 screens instead of about 12 on one screen so I guess thats an improvement..

Was hoping someone could help me a bit further.

Original Vervet:
Personality: Vervet
ConnectorInfo count in decimal: 4
Disk offset in decimal 166224
0000000 00 04 00 00 00 04 00 00 00 71 00 00 12 04 04 02
0000010 04 00 00 00 14 00 00 00 00 71 00 00 01 12 01 04
0000020 00 02 00 00 14 00 00 00 00 71 00 00 00 00 06 03

0000040

Which I thought was correct:
0000000 00 04 00 00 00 04 00 00 00 71 00 00 12 04 04 02

You still do not make a laptop display connector in the Framebuffer.

I think you mean this part:
02 00 00 00 14 00 00 00 00 71 00 00 02 04 01 04
14 00 00 00 00 71

Anything but 71 there and mac does not detect my screen.
When I leave 71 there it is detected but black or 4-12 little screens.
I have tried the first four, all LVDS and DP possibilities, this one seems to be DVI but it gives only 4 little screens instead of 12 so I thought it was the best

Any ideas?

Laptop must be the first one. Make sure you follow my guide in my sig and you should not have any issues.

Ive given up on this laptop, cant get the framebuffer to work.
Best I could do was 4 little screens.
If there is anyone who gets this card working, please post it...
