Resolution switching but no CI/QE in Snow

macindude · #1 12-04-2009, 05:47 PM

Hey all, first post here... I'm migrating from a great working Leo System to snow... So far I have Snow retail installed with Chameleon 2.0rc3. I have everything working except graphics acceleration... CI/QE worked perfectly in Leopard with just an EFI string. I've tried the EFI string, Chameleon's Graphics Enabler, and natit x64... Each with the same result: I have resolution switching (which I don't have without one of the modifications), but no acceleration (no ripple effects in dashboard, translucent menu bar, dvd player won't work, etc.). NVDANV50.kext and NVDAResman.kext are loaded and have their dependencies satisfied. Any ideas?

My System:
Gigabyte EP45-DS3L
Intel Core2Quad Q6600
2x 2GB Corsair DDR2 6400
Asus Silent nVidia GeForce 9600 GT
PCI FireWire Card
PCI Atheros based 802.11b,g,n Card
Seagate 750GB SATA HD
LG SATA DVD±RW

The injector (out of a system directory) or EFI string- CI/QE does not work.
you will help DSDT patch

I'm sorry, I don't know if I understand... Are you saying that my method is known NOT to work in Snow Leopard? What do I need to add to the DSDT?

remove all injectors, EFI string, and put this into your DSDT

Code:

hey, thank you so much! I actually happened upon this method (something very similar) and modified my DSDT about a half hour ago. It's working like a charm! So, for the record, this was the solution to my problem...
