I have new information, booting in verbose mode, I noticed that the kext RadeonMonitor.kext I do not recognize the video card even if the kext correctly recognize all Ati6000controller.kext, I must see if not having the monitor configured correctly or if this happens I have to add something to the kext, tonight I will try to create a log file of the boot, about chameleon some settings may prevent proper recognition? I turned PciRoot because if you do not active the screen stays black.

Dude, I think you have a serious problem. According to this dump, you don't have laptop display at all!!! The laptop displays in the IO register are named "AppleBacklightDisplay", but according to the dump, you don't have object with that name in the register. I found object named AppleDisplay and usually this is the name for the external displays, this object has Vendor ID 0x756e6b6e and Product ID 0x717, but there is no IODisplayEDID key for this object. Honestly, I don't know what to say.

I thank you very much for your help, I was hoping that you could risolvermi the problem but I think there is too little support for these video cards in the family RadeonMonitor.kext 6400 series does not even exist, but I tried to create it no expert on mac and I could not do, I think you have to adjust several things to run well on my monitor.

I don't really know what to do with the DSDT edit. Where should I put it under GFX0? Can you do it for me? Another thing - I don't have QE/CI yet. Will that cause it not to work? This is my unedited DSDT.

Hello everybody,

I don´t know if this is the right place but i do not know where to ask else

I managed to run mountain lion on a notebook with an i7 3610qm and HD4000 with qe / ci.

The only problem I have is that my internal display is recognised as spdisplays_display and I cannot change brightness, no controls in system settings, the hardware keys fn+up/down also do not work.

I need to mention that my display only started working when I inserted an HDMI cable to my laptop on boot....now it is working all the time, but before I had to boot with -x and GraphicsEnabler=No because Osx did not know there to draw the window server and I got a black screen (seen in system.log)

Do you maybe have an idea?

I also have attached my ioreg.txt

You need complex dsdt edits to get brightness control and some patch needs to be applied to get correct output to LCD without connecting HDMI
