I have GMA 0x2772 too, and I don't need any extra kexts because SL already has

Just modify your DSDT and it will works 100% Resolution+QE+CI

Method (DTGP, 5, NotSerialized)
 {
	 If (LEqual (Arg0, Buffer (0x10)
			 {
				 /* 0000 */	0xC6, 0xB7, 0xB5, 0xA0, 0x18, 0x13, 0x1C, 0x44, 
				 /* 0008 */	0xB0, 0xC9, 0xFE, 0x69, 0x5E, 0xAF, 0x94, 0x9B
			 }))
	 {
		 If (LEqual (Arg1, One))
		 {
			 If (LEqual (Arg2, Zero))
			 {
				 Store (Buffer (One)
					 {
						 0x03
					 }, Arg4)
				 Return (One)
			 }

			 If (LEqual (Arg2, One))
			 {
				 Return (One)
			 }
		 }
	 }

	 Store (Buffer (One)
		 {
			 0x00
		 }, Arg4)
	 Return (Zero)
 }

 

			Device (PEGP)
		 {
			 Name (_ADR, 0x00020000)
			 Device (GFX0)
			 {
				 Name (_ADR, Zero)
				 Method (_DSM, 4, NotSerialized)
				 {
					 Store (Package (0x1A)
						 {
							 "device_type", 
							 Buffer (0x08)
							 {
								 "display"
							 }, 

							 "model", 
							 Buffer (0x07)
							 {
								 "GMA950"
							 }, 

							 "built-in", 
							 Buffer (One)
							 {
								 0x01
							 }
						 }, Local0)
					 DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
					 Return (Local0)
				 }
			 }
		 }

 

Demo: you can open DSDT.dsl to see where to put 2 blocks of code,

DO NOT USE MY DSDT IT MIGHT WORKS FOR YOU BUT THE SYSTEM IS NOT STABLE, CREATE YOUR OWN FOR YOUR MB SPECIFICATIONS

DSDT.zip

Can you please explain a little more where in the DSDT this should go? I don't have any of these lines in my dsdt.

The hole Method (DTGP, 5, NotSerialized) you add at the beginning of your DSDT. For the Method (_DSM, 4, NotSerialized) search VGA, LCD, IGP and add it into the main device of these devices.

Guys,

Excuse my interruption, I'm also running SL on a GMA950, and I would like to know if there is a way to adjust the default brightness through DSDT editing.

 

Could you please help me on that ?

 

Thank you.

Guys, does anybody have an idea how to make GMA950(AE) to boot up normaly on DVI with resolution 1920x1200 (only less than 1600x1200 is possible for me). VGA on the same board (Intel D945GSEJT) does not have this problem. When I set two monitors, I can make both DVI and VGA to work full 1920x1200 when both monitors are attached, but only VGA can boot with that resolution, doesn't matter which is primary, or extended (DVI got black screen when boot up). I have Snow 10.6 4, and have tested a lot of kexts so far... Have Chameleon2 RC3.

Sorry to change the subject, but I'm interested in the D945GSEJT mobo. What did you use to get SL onto it? I haven't found much info for this model, and the ones I found have very little information.
