GMA950 GraphicsEnabler and Lion
« on: July 12, 2011, 12:56:04 AM »
Been searching for this for days really. Nothing currently works, and my final hope is that a branch of chameleon supports it with graphics enabler. I have found
http://forge.voodooprojects.org/p/chameleon/source/tree/HEAD/branches/azimutz/trunkGraphicsEnablerModules/i386/modules/GraphicsEnabler/IntelGraphicsEnabler
but how can you know if it has been compiled and added to the trunk release?
My dev ID is 0x27A2 which is supported according to gma.c but, like I said, GraphicsEnabler=yes currently does zero on lion, and all the boot loaders I could find that state explicitly that they do support 27a2 with GE=yes don't boot lion.

Any help would be hugely appreciated, I think I am in the minority with not only a GMA950 27A2, but also one capable of booting Lion.

Hi!
I have a macbook 2,1 with Intel GMA 950 running Lion.

I can try to provide some info if that is needed?

There is no onboard display connected, it´s a long story, but I use a external trough display port/vga.
AppleTV on PS3?

Thanks very much, no idea how I missed that. After some fiddling, it works. Well to an extent. QE/CI enabled, but part way through boot, screen dims to a very low setting, then stays that way. Its usable, but not somewhere well lit. Been trying to fix it with various kexts and DSDT edits including PNLF but to no avail. Also, on a side note, it only works with arch=i386. Which I think is to be expected, as I am pretty sure that the GMA950 drivers have no 64bit component. However, rather than not loading at all, they try to load but encounter an error of "malformed Mach-O File error: 0xfeedface'

Hi Rory,

Did you get a fix for the Dim display for the GMA950?

My system also goes dim a couple of seconds before going into GUI mode and then the GUI is terribly dim.  This is only on LION as on Snow Leopard it was fine, albeit needing the ScreenSleeperSolution to wake the display up.
