I've been trying to figure this out for a while now, I'm open to any and all suggestions including re-installing Lion.

So, I have Lion 10.7.3 installed and my Compaq NC6400 is hooked up to the docking station. With the laptop lid open I can use Dual Monitor no problem. I have set the external LCD as the primary so the Dock and Menu can be used from that display. If I try and enable Mirror, the display goes nuts and I have to manually delete the preferences file before I can boot properly again.

So I'm trying to run the notebook lid closed and in the docking station and simply using the external monitor as an extended display. If I run the laptop this way the monitor does initialize, at the correct resolution, but nothing but a desktop background. No dock, no menu bar.

So I tried enabling screen sharing so I could connect from my other Hackintosh and force it to move the display over, but it refuses to connect as if the other display is disabled or sleeping. I also notice if I run the notebook with display open I can hit the power button and it will prompt me if I want to shut down. But when the display is closed it won't respond. (Hitting power button will pop-up the shutdown message and activate the "Shut Down" button so all you have to do is hit enter.)

Any suggestions?

I'm not using a DSDT at the moment, but I'm not 100% sure it would help in this situation. Or maybe if someone had info on enabling video mirroring on the GMA950 without issues then I could use that approach.
