Okay, maybe I'm not quite up to speed on the latest... but what is the purpose of this?

Thank you for this post and links. I am interested in learning this. I have a question. Will this replace tonymac nvidia update for my gtx 470? Or should I continue using the your nvidia update? I am going to attempt your tutorial regardless. Thanks!

Using Chameleon's GraphicsEnabler=Yes is a great and most convenient solution for most. But some may wish to enable graphics through DSDT, in order to use dual cards, or tweak cosmetic settings. Also for HDMI edits, I've had better luck using these with GraphicsEnabler=No than with GraphicsEnabler and generic code. Finally, OpenGL scores seem slightly better when using this injection method.

This has nothing to do with drivers- you will need the tonymacx86 NVIDIA Update with GraphicsEnaber or with DSDT edits. It's simply the way the graphics are identified to the drivers by the startup routine.

Okay, thank you! I think I'll stay put... I'm way too afraid of editing the DSDT right now.

I tried to compile my DSDT by selecting copying and pasting your gt 240 with hdmi strings to my DSDT, i serched for PCI0 device and copied all your gt240 strings instead, when i try to compile, i get lots of errors, i get errors regarding devices that doesnt exist, i have a P55-USB3 MOBO and a gigabyte gt 240 1gb DDR3 graphic card, everything is working exept my graphics card which is recognized as a Nvidia GPU but with 32mb of ram, and i cant get resolutions above 1200*800 with my 22 samsung monitor, i tried nvenablers, i tried graphics enabler yes and no in apple.plist with no luck, i installed snow leopard versions 10.6.0 , .1, .2, .3, .4, .5 and .6, i dont know whats wrong, but it doesnt work out of the box, used newest iboot and multibeast.

PS: do i need to paste that enabling text on top of my DSDT in order for it to comile?

 

[Sudds]

Do not copy and paste the code from the forum as it will contain invisible characters, and cause your DSDT to compile with errors.

 

[Stork]

Good point, Sudds. Copy & Paste into a text editor such as TextEdit. But, before pasting into TextEdit, (open a new file and) change the format to text (Format > Make Plain Text), then paste. This will remove the non wanted extra characters.
