Asus GTX 580 Mountain Lion 10.8.1 - Not natively working

[Rampage Dev]

Black screen is the best thing that could have happened.

 

Now you are saying WTF? Right. Boot with GraphicsEnabler=Yes and post a new IOreg and I will patch the DSDT for the black screen issue.

I'm going to double check on my other installation, but on my new installation, doing graphicsenabler=yes has not gotten rid of the black screen... This was with the DSDT taken out, so maybe i'll try doing graphicsenabler with it back in. I'll have to do some testing.

Ok, so after installing the new drivers, I have tried the following on my new mountain lion installation:

 

Repaired permissions from my Mountain Lion installation thumbdrive to see if maybe they just weren't installed properly.

 

Booted without your latest DSDT with both graphicsenabler=yes and graphicsenabler=no

 

Booted with your latest DSDT with both graphicsenabler=yes and graphicsenabler=no

 

Using the HDMI port instead of the Display port thinking it just may not be initializing the correct port.

 

A Voodoo dance.

 

 

Nothing seems to have helped

 

 

It is important to note that when I check it in verbose mode it says the NVDAGF100Hal.kext is "loaded and registered" and there are no geforce related issues to speak of.

 

Also, when the screen goes black there is no hard drive activity afterwards. I would think that if the system was still booting properly - yet without working graphics - that I would still see some activity.

Do u have an old vid card u can try? And did u try installing kexts manually? The installer didnt work for me for whatever reason... Sounds like it installed properly tho. Hopefully someone w more exp than me has some input lol
