My Mac OS X 10.6.6 is up and running, but only with an externel screen connected to my notebook. If I don't attach an display, I only get a black screen on my internal display. With the display attached, the internal display stays also black.

 

Thats what the system information shows:

dsdt edit the _DOD switch first to LCD 0x00000110 or 118

 

Could you share why you had provided this specific instruction?

 

I have a Sony VAIO VGN-AR840E, running 10.6.8, but get black screen whenever I attempt to enable GraphicsEnabler at boot or in apple.com.Boot.plist. The laptop has what others have called, LVDS. So, absent using GraphicsEnabler (or some other solution that noone has come up with), I can set the resolution within the plist file, but do not get QE/CE, and video files and online web is very choppy or non-visible.

 

Looking forward to your response,

Same problem here... since at least 3 years..! :P

I have a VAIO FZ21M with Nvidia 8400M GT.. When I use Graphics Enabler i can see (with -v option) that the graphics card is fully recognized but after system loads up, the internal screen goes black... Very bad..

I've tried almost everything, DSDT edit apart cos I'm not able to do that.

If someone has a solution PLEASE post it everywhere :)
