Did you enable the GraphicsEnabler and have you put the PNLF device in DSDT?
Also the 2 kexts need to be installed in /S/L/E, removing the old 2 kexts in question...

Yes, I did. If I remove PNLF device from DSDT and use only your modified AppleIntelIntegratedFramebuffer, native resolution works. With PNLF in DSDT and/or using your AppleIntelGMA950, get stuck in black screen.

I have a new version...
Try this one and download the patched ACPI from the chameleon (VoodooProjects) forum.
Very welcome are any GMA VBIOS files I don't have yet (GMAX3100 style or GMA950 style...)

Can you provide a diff from your original DSDT? Mine is different.

Thanks.

Hi Andy.

It works on acer travelmate 2490 with gma 950(27a2).
Proper resolution is patched, i know that my vga bios doesnt have 1280x800, (used i915resolution patch on linux, and now grub2 with 915resolution).
Removed all lines from dsdt for graphics, enabled graphicsenabler,removed grub2 resolution fix and it works. I don's see any difference between dsdt patch and yours boot file.
Does mirror mode works for you?
Could you build boot file without debuging?

Thnx.

Haven't tested out mirror mode as I don't have an extra display around...
Could you also please dump your VBIOS and post it?
It would be handy to check if there is an extra id needed for your card... (it reads chipset id from VBIOS...)
I will make a boot file without debugging as soon as everything matures a little (will be integrated also fully in RC5 when it comes out).

Just my two cent ...

sh-3.2# kextload RadeonPCI.kext/
sh-3.2# ./RadeonDump -d
Found a device of class RadeonPCI: IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/GFX0@2/RadeonPCI
it matched on name "display"
Found a device of class RadeonPCI: IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/display@2,1/RadeonPCI
it matched on name "display"
sh-3.2#


I hope to you this is more informative than to me ... dump from 945 mobile ...

Gonna try the new boot now.


Cheers Goron

Edit:

new boot doesn´t change situation: still no .kext loaded and no resolution change ;)

Now a fix for GMA950! (Or is there one?)
----UPDATE

Or am i being stupid as on the picture it says GMA950? I have a D945GCLF it has a GMA950 but has 945 in the name? Im very confused?

----UPDATE

Im quite sure it will work with my system as i have the same model of stuff as on the screen shot ima do it!

How do you add this to DSDT? Using TextEditor?

As when i open it with text editor all the characters look werid and what you said to add is like normal abc type stuff.

You have to decompile it, edit using a text editor, and compile it again.

About mirror mode and new Framebuffer: all new Framebuffers have Macrovision (Hello iTunes Store).
Last framebuffer without Macrovision is v5.3.0.
I think we need modify vbios for mirror work. Someone can make a dump VBIOS GMA950 from MacBook or MacMini?

@Andy Vandijck
Your bootloader can shadow vbios for Intel?

I have an Acer ao150 with gma450, i got it to work in native resolution and QE (menu is transparent),
all works fine, except the external monitor. all garbled as some have mentioned.

I am not sure if installing this package would help anything?
Would it fix the external monitor?
Anyone knows?

Could you try latest boot file from Chameleon forum?
It makes all connectors visible (including 0x27A68086)...
I need to know which connector is used for this...
If it uses this also, I'll patch up the kext for this one too...

Will this fix work for 10.6.3?

Currently, I'm using AppleIntelIntegratedFramebuffer.kext from 10.6.2 (suppose, I download it from this forum), OpenCL works fine, but cannot wake up correctly. If use stock kext from 10.6.3, I got garble screen and a lot issues.

Here is the ROM dump

Hi, Thank you for replying, I thought i installed the latest chameleon, how can i know if i indeed did or not?
a version somewhere? a file size? a cksum i can run against a file?
Thank you
PS: The 2nd monitor works if i use it as a 2nd monitor, but if mirror mode, that's when it gets messed up.
